May 29th - San Antonio back to Vidor via Austin.

We woke up and hit the road, we decided to drive back to Vidor via San Marcos (large outlet shopping malls) and Austin, where we toured the campus of the University of Texas and saw the Capitol building. After leaving Austin we drove back to Vidor, and stopped and ate in Bastrop Texas, where we saw a nice thunderstorm (not severe, but alot of lightning and heavy rain.) On a side-note while we were in San Antonio, parts of the Beaumont TX area received up to 15 inches of rain in less that 24 hours. So on our way back through Beaumont we saw a lot of flooded fields, (one of which housed an Alligator farm, and some of them escaped due to the flooding). We finally arrived home, and went over to another friends house for a meal of deer-wraps (Deer-meat wrapped in bacon, cheese and peppers and soaked in honey, mmmmm).

May 28th - Travel to San Antonio

We got up and made our way to San Antonio Texas (about a 5 hour drive from Vidor). It was a fun day, we saw the Alamo, a lost battle for the Texan army but inspired a turn in the war that saw Texas win its independence from Mexico in 1836. We also ate a very good Mexican food place in the Market, and walked around the Riverwalk that night. San Antonio is a fun place.

May 27th - Crawfish Bowl in Vidor TX.

A much needed rest day, (NO CAR TRAVEL).

We decided to stay near my house and had a swim (in which I got a severe shoulder sun-burn). After that we had a crawfish bowl and played some pool.

May 26th - Galveston Texas

We decided that since the weather wouldnt be exciting we would make the most of our vacation time. We drove from Vidor to Galveston via Crystal Beach Texas taking us on the ferry that carries cars from the Bolivar Pennisula to Galveston Island. While in Galveston we tested the waters of the Gulf Of Mexico, (warm enough to swim), and had some food. From a weather perspective we visited the Great Storm museum which catalogs the events of Sept 8-9, of 1900 when a hurricane swept over Galveston Island killing an estimated 6,000 people, still the worst natural disaster in US history. On the way home we at some good sea-food at a resturant along the Inter-coastal Waterway which is a protected in-land canal that carries barge traffic from south Texas to Florida.

May 24th - night in Wichita Kansas

Well after an exhausting 24 hours of driving we had a nice rest in Lincoln NE before what we hoped would be another chase day through parts of south-eastern Kansas, however, it wasnt to be. We tracked the dry-line across much of Kansas through the day, but the cap was just too strong, no storms fired along the boundary, and it was a quite day. After the spending the day hanging out with some old friends that were with the Mississippi Storm chase group in Gas, Kansas, we decided to follow them back to Wichita, Kansas to hang out. We had a few drinks and a nice catch-up that evening. It was becoming pretty obvious that our storm chasing days were number (well up). So we decided that we would get in the car and make the long trek back to southeast Texas on the 25th.

24 hours and 1240 miles.

Well the first chase day arrived.

It became obvious that the 23rd of May would be a chase day across the northern plains with a potent 500mb trough swinging through the northern plains, and a surface low pressure system moving through southern SD. Strong southerly wind flow and strong surface heating due to sunny skies allowed for the opportunity for convection to form from Kansas, Nebraska and South Dakota.

To make this area from southeast TX, me and two friends left at 9pm on the 22nd. We drove through the night and arrived in Columbus, Nebraska (central NE) around 2pm. After meeting up with some other friends and looking at data we decided to move back to southern NE around 4pm to intercept. Supercells did not really ever get going, instead a Mesoscale Convective System formed which we watched move over us with 40-50mph winds and heavy rain. The only thing that was exciting about this storm system was the nice shelf cloud that formed along the front edge of the squall line. Otherwise from a storm chasing perspective this was a dissapointing day.

We finally arrived back at the hotel in Lincoln, Nebraksa around 9pm on the 23rd after 24 hours of continous driving and 1240 miles being logged during that 24 period.

Quick outlook for the 24th. Only viable chase opportunity will be through western Illinios. At this point the risk of tornadoes is small, and storms will likely evovle quickly into another MCS. Unsure of whether this will be a chase day, so stay tuned.

More detail to be edited in later - as well as non-weather related chase notes.

Flight and first two days...

(may be edited for more content later - im tired)

May 21 - Woke up and drove to the airport, flew from London Gatwick to Houston. Flight was good, a bit of turbulence associated with an occulded low pressure near the British Isles, the trek across the Atlantic was smooth...bumpy again over Nova Scotia, but smooth over the rest of north america. Landing in houston the afternoon was a bit bumpy with daytime heating thermals near the surface...Saw the family, had a meal, watched a movie, then picked up my friend from the airport and arrived home around 2am...

May 22 - Woke up at 9am -- hung out around the hometown -- then went shopping and bought stuff for the stormchase...which i will detail in the next post.

Friday, May 19, 2006

Model Analysis, May 19th.

12z GFS - not looking pretty i must say, this run is a little depressing.

This may be the last one before the flight, so here it goes.

May 22 - Ridge over the plains, but a trough starting to dig some vorticity over into UT, maybe a good sign? - we will see.

May 23 - Flow across the plains become more zonal - with a small trough through SD, could trigger a few thunderstorms along the ND/SD border.

May 24 - Whats left of a minor trough slips through IA, allowing for a few storms i would imagine, but nothing to get too excited about.

May 25 - Ridge returns to the plains, as a trough moves into the mid-west, through southern IL model suggest a few storms would be possible across MO, we shall see.

May 26 - Another trough beginning to affect the west coast, this throws another bit of energy across the northern plains, with the GFS surface analysis firing a few storms through the Dakotas again.

May 27 - Trough stays put over the western CONUS, scattered thunderstorms across the northern plains, doubtful they woudl be too severe.

May 28 - not much change from the previous day...

May 29 - again, a few thunderstorms possible across the Dakotas, but nothing worth chasing.

May 30 - broad ridge across the plains with a little weakness across the northern plains, gfs puts some storms through IA, but again, not worth chasing.

May 31 - this woudl be my last chasable day, but there is nothing to write home about in terms of storms...

Other Global Models, Analysis, May 18th.

Here is a look at what the other big 3 models are thinking right now - they only go out till the 23/24th, but have a look.

http://meteocentre.com/models/modelsgem_e.html

GEM (Canadian) - 12z

May 23 - upper trough approaching the rockies, with some hint at storms across the western part of the northern plains, through eastern WY and western NE and SD

May 24 - Shows a good upper trough swinging through SD and into northern NE - this is good to see, and in line with GFS thinking...

ECMWF (European) - 0z

(last panel)
May 23 - Seems to be a little quicker with the trough than the GEM and GFS, arriving it more on this day than the 24th, it also seems a little weaker...

UKMO (UK Met Office) - 0z

(last panel)
May 23 - Looks like this one is in line with GFS/GEM thinking having a decent upper trough over the Rockies setting up for a trough in the upper plains on the 24th.

Model Analysis, May 18th.

12z GFS:

This is an interesting model run...the 24-26 look interesting across the northern plains and then some type of short-wave, vort max gets left behing over the southern plains on the 29th and 30th...either way, its give some hope (more than previous days)...see the details below:

May 21 - Ridge over the plains - no storms.

May 22 - Continued ridge over the plains, upper low nearing the northwest coast.

May 23 - Ridge beginning to weaken slightly, with a little southern vort. digging into southern NV and CA, giving hope of something to come, but not much...

May 24 - Woohoo - Trought swings through the northern plains, energy from northern KS to SD Surface low showing up in northern KS as well, this could be a decent severe weather outbreak in an area from northern KS through southern SD (mainly over NE (the cornhusker state baby).

May 25 - A decent vort max remains over the Dakotas, allowing for another (all be it smaller) shot at severe weather through eastern Dakotas and into MN.

May 26 - Interesting day here...through begins to dig back into Kansas (although very positively tilted, there signs of heavy precip through eastern Kansas and southwest MO), also a look at the 250mb level shows (if you try hard enough) you could say there was some right rear quad of a jet streak in the area -- Im not sold on this set up, but hey, it better than a ridge!

May 27 - Still a bit of troughiness left through the eastern plains, but nothing really to support severe weather - fun time looking like its coming to an end.

May 28 - Omega block beginning to return to the plains - no svr wx.

May 29 - Not sure what it is on this chart, but there appears to be some kind of shortwave showing up in Kansas, I think this is spurious, but the precip and 850mb field could hint toward some dryline activity through the TX and OK panhandle...doubtful though.

May 30 - hmmm. that same piece of energy is again showing up through western NE - this will be something to watch as the precip field does show something through eastern NE and KS...

May 31 - broad weak trough across the eastern half of the CONUS, with a ridge beginning to build back in the plains...(its my last chaseable day anyway, - so time to head home and see the family).

Wednesday, May 17, 2006

Model Analysis, May 17th.

0z GFS:

May 21 - Omega block over the Rockies, northwesterly flow through the northern Plains, if anything does develop - it will elevated and not great for chasing.

May 22 - Blocking pattern continues, to whos surprise?? not mine...

May 23 - Continued ridging with the axis almost directly over the Great Plains -- its like the big man is laughing at stormchasers...

May 24 - Rigde starting to transition to a more zonal flow, but still nothing of note to the west to hope for.

May 25 - Almost complete zonal flow across the plains, -- there is a small surface low showing up in SW KS, could be 1 dryline storm, but thats not even worthy of a slight risk, I doubt.

May 26 - SEVERE WEATHER possible...a shortwave through swings across MT and ND, providing a chase day for central and eastern ND - would I drive for it, Im not sure.

May 27 - Vorticity begins to move out over the Great Lakes region, and yet another ridge begins to build back over the northern Rockies, with the Great Plains still in zonal flow.

May 28 - A flattened ridge back across the nations midsection (insert sad emotiocon)

May 29 - Zonal flow

May 30 - A small shortwave trough showing up across northern MO, slp suggest there could be some storm development, but i feel this is a reach, plus, this is my last chasable day.


SO IT ENDS, ANOTHER TERRIBLE MODEL RUN, its beginning to look like my family will see alot of me over this visit, this makes the moms happy, but i wish there could be at least a couple of chase days...

comments if you wish.

more later if i have time.

Tuesday, May 16, 2006

Model Analysis, May 16th.

6z GFS:

May 21 - Rigde Block over the Great plains, no good.

May 22 - Still significant blocking.

May 23 - Still a ridge, vort max trying to sneak into the upper Great Plains, but not really very significant.

May 24 - again ugly - this aint looking good.

May 25 - zonal flow across the plains - bad.

May 26 - another little piece of energy running along the jet stream across the northern plains, not very significant, and not worth chasing for sure...

May 27 - This is a chase day vort max does swing into the western part of the northern plains, and would probably trigger severe t'storms across eastern ND and SD as well as MN, thats a loooong way to drive, doubt i would do it.

May 28 - Another chase day across ND and MN, starting to get my attention for possibly driving that far, as the trough becomes a little more neutral.

May 29 - negatively tilted trough could cause a severe weather outbreak over eastern parts of Canada, hahahhah...NO THANKS!

May 30 - Storms move furthern off into eastern canada along with one of the better peices of vorticity i have seen on the GFS since i have been keeping up, too bad its not about 800 miles further south!

We will continue to hope for something better tomorrow. I must say, it is a little disheartening from a storm chase point of view. Since I have been writing the blog on may 7th, there havent been too many chaseable days show up in the model...The ridge that is there now, surely cant last forever, if it does, it could be a long dry summer for the Plains, and that could equal Dust Bowl....

Monday, May 15, 2006

just an update...

i just wanted to state my "againstness" to todays 12z GFS...

it can take the ridge and go to the hot place...

Quick look at the ensemble runs, dont do much better, with most memeber not really putting a trough into the west until the end of the run (around May 30) -- one member though, which I am in favor of, has a decent trough swinging through the middle of the plains during the mid to end of May...that means there is still a percentage chance..(not long to go now though) - May 23 will show up on the Day 3 SPC risk (not that they are tell all of severe weather) in 5 days.

goodnight.

Model Analysis, May 15th.

0z GFS

Some Excitement!!!

May 21 - Ridging still prevelant through the plains on the 21st, but a quick look off the west coast gives some excitement of whats to come...

May 22 - Trough begins to dig into southern California and AZ, still significant ridging through the plains, but this looks like the last day, before the pattern starts to break down.

May 23 - This is the day, trough swings through northern NM and southern CO allowing for a severe weather possiblity through western KS , panhandle TX and OK. This is the best day I have seen on the GFS in this period since I have been monitoring its progress around may 7th.

May 24 - The trough swings through the northern plains giving the continued risk of severe weather through MN...at least its something.

May 25 - Vorticity begins to move away over the Great Lakes, with ridging beginning to move back over the plains.

May 26 - Ridging over much of the plains, but trough swinging across the northern plains could bring the risk of some severe weather across ND. (a bit too far north for me probably - unless it looks nastier than this)

May 27 - Probably the 2nd best chase day I have seen as this vort max treks a bit further east, providing a good severe weather risk through northern MN.

May 28 - Omega block over almost all of the plains.

May 29 - Still a ridge through the plains, not a good chase day.

May 30 - ridging, not good for chasing.

What to do, what to do...

Sparked by the latest GFS run, it got me thinking, what in the world will I do if there is nothing to chase....

Here are some thoughts.

I will see the family quite a bit, which will be nice.

And then hang with some old pals, incorporating some road trips in there as well, here is what I had in mind on places to go.

1. San Antonio/Austin area - Riverwalk, Alamo, UT area in Austin, food, markets, etc.

2. Dallas / FW area - Have a bunch of buddies in this area, good places to eat, and maybe take in a Rangers game.

3. Galveston/NASA - always a fun day, go see NASA first thing in the morning, then just spend the rest of the day in Galveston, walking the beach, eating some food, and generally catching some sun.

4. Houston area - Friends and alot to do around the houston area...

5. Baton Rouge/New Orleans - I havent seen the area since the destruction, I wouldnt mind getting to New Orleans early, and eating at Cafe Du'mond, then seeing the French Quarter, and Bourbon, and maybe driving around some of the affected areas. The head back through Baton Rouge on the way home and see the old school, and maybe eating a one of my fav. resturants in the ara, (Superior Grill, Canes, Ingas, etc.)

6. Amarillo - A long drive, but if there really isnt going to be anything to chase, what the hell. Could take in a hike at Palo Duro Canyon and maybe camp there, as well as a meal the Big Texan Steakhouse.

7. Oklahoma City - try to meet up with the MSU storm chase group and see some old friends, or maybe meet them a little further down the road at Elk City (always a fun night at the Holidome there) - OKC woudl be nice for some food, and seeing the southern Plains for my buddy.

8. New Mexico - (Carslbad Caverns, White Sands, etc.) if we are feeling a little more adventurous, this is a cool drive, with lots of places to camp and hang out, we will see.

9. Florida/Bama coast - white sands, sun, drinks, and general fun (if there is anything left of all that?)

Let me know your thoughts, if you have any...

Model Analysis, May 14th.

Im not even going to justify the 0z GFS with comment.

It looks so bad for chasing for pretty much the entire run, with a very large ridge over the nations mid-section, if this verified, I would be hanging with the family for the majority of the time.

Ill look back on later runs today, and perhaps post again if anything pops up.

Saturday, May 13, 2006

Model Analysis, May 13th.

Sorry - I missed a few days....

May 21 - Northwesterly flow over the northern plains, could provide for some MCS development across IA, WI and IL - but wont be chasing anyway.

May 22 - Vort max over the northwest - but slight ridging across the plains could allow for some northwesterly flow convection, but not likely to be a good chase day.

May 23 - Zonal flow

May 24 - Zonal flow

May 25 - Yuck, zonal flow continues across the plains.

May 26 - Ridge over the plains not looking good - troughing beginning to show up off the west coast though - could be signs of good things to come??

May 27 - Upper low beginning to affect the west coast of the US - but still significant ridging across the plains, unlikely to allow for any severe development.

May 28 - Large trough setting up in the west at the 500mb level, but slp chart shows not significant precip in the plains, this is looking better for the last couple of days of May though.

All in all, I am not impressed, hopefully things will change, or that at least the last few days of May could get active with this low in the SW.

Wednesday, May 10, 2006

Model Analysis, May 10th.

0z GFS:

May 21 - Nothing to chase.
A large upper trough camped out over the west coast and ridging through the Great Plains will supress any real convection, although there could be some elevated lee storms over the northern plains, this looks like a bad day.

May 22 - ???
This is a tough day to figure out...looking at the slp panel, there is a bulls-eye of heavy rain over the bootheel of MO, however, the 500mb shows ridging through the Great Plains, with a stalled upper low still back over the west coast...I cant really figure what would cause precip in this area, maybe diffluence aloft, maybe warm air advection, I dont know, either way I dont think this looks like a set up for severe weather.


May 23 - North Dakota?
The upper trough over the southwest finally begins to swing out however, the Vorticity rides up the ridge into the extreme northern plans, allowing for some thunderstorms to develope over the US/Canadian border, yuck!


May 24 - Minnesota?
Again, any severe weather that could form would be along the US/Canadian border associated with some PVA and a surface low driving through Minnesota, thats too far away for me...


May 25 - Ohio valley?
A short wave appears to be possible just west of the ohio valley, along with being in the front left region of a jet streak, this could aid in enough uplift for some severe convection, but I am not holding my breath...

Tuesday, May 09, 2006

Model Analysis, May 9th.

May 21st: Elevated storms in eastern CO?

Zonal flow at the 500mb level across much of the central US would keep storm development at a minimum, lee troughing to the east of the Rockies could produce some elevated thunderstorms, but this doesnt look like much of a chase day.

May 22nd: Storms in MT and ND?

C0ntinued zonal flow over the southern plains, will produce little in the way of thunderstorms, but again, some lee side troughing over the Rockies could provide the focal point for a few storms over eastern CO and western KS, and with any backed suface winds I guess one or two storms could trigger. The more interesting feature on this day is the large vort-max over the northern plains (MT, WY, ND and SD) PVA and southerly flow at the southerly flow at the surface could potentiall aid a thunderstorm outbreak over eastern Montana and western ND (no thanks to driving that far the day after I get off a trans-atlantic flight)...we will hope for something better.

May 23rd: MCS in KS?

Getting better - The vort max that was across Montana will slide southeastward through teh day, and some PVA associated with that would aid for thunderstorm development a little further south - unfortunately the forcing with this looks northwesterly, ie. MCS and linear developing. So I am not getting my hopes up if this situation pans out.

May 24th: storms in the upper midwest?

Vort max continues to hang out over western IA and eastern NE, an amplified ridge over the rockies would help to shove this PVA into the uppper mid-west, however, at this point the model doesnt really show signs of sigificant development of storms. -- to lead on from this, the big amplified ridge is being aided but a trough digging into the mid-west, hopes would be that this trough continues to develope and begins to spit waves out into the southern plains in the period after this...

Monday, May 08, 2006

Model Analysis, May 8th.

GFS Valid 0z, May 8th.

May 21st: Not good.

Uh-oh, not such good news with todays GFS. As per norm, the GFS is undergoing its radical swings in the 10-15 period. Todays swing takes it in the wrong direction for exciting chase material. During the day on the 21st a large ridge (Omega block) is in place over much of the western Plains leaving for some northwesterly flow (and weak at that) so there wouldnt be much to chase at all.

May 22nd: Not good.

Unfotunately the ridging (blocking) in western Plains continues, a little more in the way of northwesterly flow out of the northern Rockies, and the model hints at some rain/thunderstorms in the northern Plains, but as we all know, that flow in that area means elevated bases and almost no risk for naders...

May 23rd: Something, but not much.

SIGNS OF LIFE, albeit, not great signs, but hey, its beter than nothing. 384 hours out, a small trough begins to show up on the 500mb chart over the desert southwest, while northwest flow continues in the northern Plains. The SLP/Precip chart shows a bulls-eye of rain over SW Kansas, but I can not tell if this is an MCS from the northwest flow or if it could be due to some PVA from the trough that is developing in the SW...I guess it doesnt matter too much, because I doubt it will be there in tomorrows run.

Now you are up to date! ha.

Comments are welcome.

Sunday, May 07, 2006

Model Analysis, May 7th.

0z GFS Run:

May 21:

A trough starting to build in the SW will move out into western New Mexico during the morning hours on the 21st. Good PVA and WAA into the southern Plains would make for a decent chase day across southeasternKansas and NW Missouri (although it looks like itwould go linear pretty quickly with decent forcing)(Either way - this is the day I am flying in - so its not like I could chase it anyway)

May 22:

This is the last day showing up on the Model at this point, another trough will push a vort max into SW Kansas - causing another shot of severe weather across much of central Kansas [this situation seems better for sustained supercells]...(this would suck though, as I am not sure if we would have time to getthere before the afternoon/evening outbreak.

The good news is though, that while much of the middle part of May is looking pretty bad for chasing in the plains, the pattern starts to become more interesting right around the time I arrive in the states...lets hope this trend continues and it could be a fun time toward the end of May!

Its been a while...

I have not done my blog justice, I created it, left a few posts and then neglected it...I will try to do better. For now, I will turn my head to Severe Weather Season and my upcoming Great Plains Stormchase...Starting from today - I will be updating this daily up to and during the chase with model analysis and reports from the road when the chase starts on May 22. Thats it for this post, more to come.
