11/23/04 NOW: TX, LA, MS

Might as well shift the discussion over to a now thread, as two T boxes are already issued along with active supercells. Of particular interest at the moment is the cell west of Austin, TX which could have the potential to become surface based over the next hour. In fact, I see a tornado warning was just issued for this cell.

Just a reminder to all:
Target Area Rules:

3) Prohibited content. Stormtrack strives for a very high signal/noise ratio in Target Area since many chasers use this forum on the road and can't sift through pages of fluff. These items are prohibited and will result in Target Area privilege suspension:
-- NOAA/NWS products or bulletins posted in their entirety. If you post such a product, trim it to the bare minimum and always include informational comments.

So, just a friendly reminder to not post NWS products in their entirety (or almost entirety) and to always make a comment on the product being posted...
 
earlier discrete cells near Austin have merged into more of a convective complex, yet ion the NE side an HP type cell has recently developed very strong rotation (including TVS). Torn warn for Robertson county, looks to be headed toward Franklin. A few weak tornados were reported earlier from this complex.

Just got back in from chasing for work.

In Smith County, with the tornado warning, I was able to observe a good part of the storm after it passed my position. No rotation or ominous features observed.

Hail was the problem. We were at I-20 and Hwy 69 in Lindale and got wind-driven quarter sized hail, and went to a home just to our east where we shot some 1.5" hail. That hail dented cars, but shattered no windows.

News flash! "SantaLand" on I-20 in Smith/Van Zandt county has been seriously damaged. This is one of those drive through christmas light places. It's one of the biggest in East Texas. We just got off the phone with the owner who is in tears.

Add: Video will be on KLTV.com later today.

Situation becames more interesting: SPC has issued a PDS tornado watch on the border Luisiana-Texas. The convection from the radar seems to be more "sheared". Let's see what happen.
 
New torn box of the PDS variety. I'm surprised there is so little interest in today's event. Is this entire area unchaseable? I'm familiar with the Piney Woods, but thought today has been west of the thicket. That said, the most favorable region is sliding east of College Station, so maybe trees are starting to become a factor for viewability.

I think the heavy precipitation is reducing visibility and accessibility to the point that it is almost unsafe to chase if someone is not absolutely familiar with the area.

Some of the small storms developing around the Houston metro are rapidly developing strong shear signatures. This may be the start of a big show.

I was telling the same thing: moreover in that zone there's the best combination between low level shear and MLCAPE.
 
Looks like the HOU area is really exploding with tornado warnings....
 
Newton TX

Tornadoic storm moving toward the the town of Newton TX Tornado Likey Tornado Warning Newton County at 5:12 PM. This is a bad one.
 
Tornado Damage Just South of Newton TX

I talked to the Newton county sheriff’s office damage reports are coming in at this time SSW of the city of Newton at 5:29 PM.
 
I screen shot some radars from the Ft. Polk, LA radar site. There was a tornadic storm about 10 miles to the north. I can't remember the last time I saw this kind of definition on a radar. I can pinpoint the circulation on base velocity, so it must be pretty big. The shots are base level, which works out to about 600 feet of elevation where the center of the storm is. It's either a really low wall cloud, or a tornado that's pulled quite a bit of debris into the air.

Why I'm up right now, I have absolutely no idea...

but the tornado outbreak continues with RAPID rotation over downtown New Orleans, LA visisble per local radar. No reports of damage so far, but deaths, serious injuries, and damage reports from TX to MS extending to AL in this significant nighttime event.

:(
 
As noted I was stuck on business travel on this chase day. On the way back from Seguin on Interstate 10 we encountered some straight line winds at about 7:40 pm. The winds top at about 45 mph and seemed to align with the passage of the front. I heard reports of tornadic cells to the north and saw one good cell to the south. The only good thing to say about this day is that I learned, for future reference, that east of San Antonio to Houston could be excellent chase country. Its fairly flat, the trees are not to tall and I10 is an excellent east/west root outside of the urban areas. So now I have three chase directions to plan for, west into the big bend region, north along 281 up to Dallas and east on I10. South is limited on 16, 37 and 281. I35 south is not a great option due to road limitations. Oh well there is always next spring.
 
I've just had reports on the news here this evening that at least four people are dead in LA now — most of the damage they showed looked about F2, possible F3 (making the big assumption that all the homes they showed were well-constructed — but there's another thing: they were all homes, in a residential neighborhood, not trailers). Odd how much this is going like that whole 11/21–23/1992 outbreak . . . that had a big one — a long-track, F4 event over N MS — at night. THis now could have a while to go, and it sure doesn't sound like chasing weather — y'all watch yourselves there, y'hear?

EDIT 11/27 — my quoted death toll is too high; only seems to be one death.
