The warm sector east of the cold front today will be characterized by very high wind shear but marginal instability due to modified lapse rates and cloud cover. It appears that a vast majority of the convection today will be disorganized and "junky" in nature, but the extreme low-level shear values could result in a few significant tornadoes over the Piney Woods of Texas into the jungles of Louisiana. More will be posted about this event as it unfolds, as well as pictures from the beautiful supercell from yesterday intercepted near sunset west of Coleman, TX.

PDS out for NE Texas, SE Oklahoma, and most of Arkansas. Take cover Heidi!!!!
Im currently in Hot Springs, AR on vacation, just for reference.
Second PDS watch out now!! Looks like its going to be a big day!
I can almost guarantee that we're end up with a HIGH risk now... this is CRAZY!!!
ok, new day 1 out... And I stand corrected, they've just extended the Moderate rick farther to the north.

Im in lafayette, louisiana .. and the weather here is soo windy i can barely stand outside and the sky has a odd color to it.
Last night about 7:30 we had a tornado warning. No reports of touch down. However it looks like things might start to fire off here in about an hour with a lot of heavy stuff to our south west.
The DFW area ( They have just stopped all flights till 4:00 pm due to weather)looks to be priming up at the present and tracking our way. Also considering storms typically strengthen just before hitting Lamar county ( Could it be all the lakes and the red river help to feed these storms by having natural boundries in place to help storms in this area. As far back as i remember Lamar has always had very active weather but with this said i lived in Texarkana for 8 years and heard the sirens only twice but in this area in the same amount of time warnings where issued on 13 different occassions )so it could well be a very active afternoon here.
Everything is set for the outbreak, except the Lapse Rates, which are currently unacceptable. Dont expect much with the current rates, but if they go up, then this could get interesting.
I don't like the orientation of the shear. VERY surprised at the massive PDS watches issued.
The hodographs do not look very favorable for large tornadoes...but I've seen crazier things happen.
Reporting in for Shreveport, LA: Tornado watch, 20 mph gusts. Looking kinda dangerous out here, I think we can switch into high as well. We'll see...
that would scare me to be where you all are hope everyone is ok
I'm in Shreveport la, Looks like some good cells will soon begin forming
My grandmother live's in Conway Ar. she said the tv weatherman are all over the tv . Seem's they are still shook up from super teusday outbreak. On another note , we are up to 6.5" of rain with more on way.
I agree with Reed. Thought all along this thing for the coastal plain of TX was being way overblown by SPC. Seems to be panning out that way. Good call to chase yesterday and sit out today. Calling a PDS when one dosen't exist is not the way to improve public attention to severe weather.
just like after the may 3 outbreak , they will be jumpy for awhile .
I'm starting to like this one more.. I keep hearing Reed and everyone saying not to expect much, but when I walk outside, the air has a very oppressive feeling.. the last time I remember that feeling was November of '05, though this is a weaker feeling, I think it will be enough.. Time will tell!
Cells are starting to pop around me, might get interesting!
Downgrade to a Slight risk now... This is odd, it feels like a Moderate+ Risk day outside, and yet they keep downgrading... anyone feel like explaining?
Um, My guess is because there has not been one tornado report, yesterday, there were at least two or three that I know of. I left to chase at about 7:45 this morning, and stationed in Tyler Texas, I waited, Nothing happened. I was VERY surprised at the massive pds watches over Louisiana, Texas, and Arkansas, I chased the first cell that developed at about 4:00 pm, it was NOTHING! Just some darker clouds, lightning, thunder, and very light rain, I then began to head towards another cell, that fell apart before I made it to it, I am almost home to Shreveport now, where there is a weak thunderstorm, Looks like I should of agreed with you guys reed and went out yesterday.
I dunno... 2 tornado warnings out now with a Severe T-Storm in the mix, and several bands of strong/severe storms heading my way.

Looks like something no?
Lapse rates were poor in the moderate risk area. Also LI values were not that high. Just something I noticed.
