2/24/07 NOW: LA / AR / TX / MS

New tornado warning up on the cell SE of Shreveport. nice rotation is evident on SRV and there is a decent hook developing too. what happened to the original NOW thread?

EDIT: NWS says this cell is moving NE at 60mph!
 
I am sitting at the Comfort Inn in Greenville, Ms.

I want to go after the storm south of Pine Bluff but do not want to take off after an embedded storm and miss anything isolated that might pop up in the next couple hours. Plus if I left now it would be close to impossible to catch.
 
Yea, that cell appears to be developing a hook echo on the Soutwest side, and SRV1 is showing a weak couplet forming Southwest of Star City right near Cornerville on State Route 11.

brandon if i were you i'd ignore the embedded stuff in AR and pay close attention to the tail-end charlie NE of shreveport. its starting to look pretty intense!

EDIT: there is rotation now associated with the tail-end charlie and also further up the line in the embedded cell approaching el dorado!
 
Does anyone have a live web link to any of the TV stations in Shreveport, LA?
 
really nice hook echo now present with the tail-end charlie. looking really impressive on radar!

EDIT: thats definately the best radar presentation i've seen all weekend! i'd be surprised if there isn't a TOR on the ground.

I am watching the area from Greenville to Monroe, LA and southwest hoping to see some discrete cells firing. A couple looked like they were going to go but the updrafts are not strong enough and they are getting torn apart. I do see that this area to the Ms river is getting a little better clearing and hopefully something will take off. I don't feel like chasing a tail end unless I have to.

I heard that! but right now the tail0end is THE most impressive storm in the nation. IMO the cells across far Srn AR and LA will pose the best threat for tornadoes. aols, just noticed tha SPC has issued a new PDS TOR watch for a large portion of MS until 9:00. looks like it'll be a long day.
 
This cell is really cranking... GR2AE's new Rotation algorithm is picking up some intense circulation... here is a 3D view

One big problem is that this cell is about to pass into radar no-man's land. It's rapidly moving away from KSHV and there really isn't another one close enough to the northeast to give a good view. One can see it on KLZK but it's not going to get any closer to that one, and it's not close enough to KJAN yet to be visible. Looks to me like the south-central US could use an extra radar station, right in the middle of a triangle between those three!
 
currently at tupelo public library...fixin to head west on 278...man, a PDS watch, and just look at the sounding...probably going to see my first tornadoes today...hope so

BR248 out of Shreveport will not have a problem picking it up for a while still.
 
LZK should cover it good enough for us to see any mid-level rotation until it gets closer to Memphis!
also, it looks like the cell south of Shreveport is trying to rotate a bit now.

SPC mentions in thier latest MD that the section of AR that our potentially tornadic tail-end is going to be moving through is also the area of highest risk for strong/violent tornadoes.

nice meso still evident with potentially tornadic superdell between pine bluff, ar and greenville, ms. curious to see how this cell merger will affect it over the next couple min.

EDIT: appears that the intensifying cell NE of shreveport and just N of I-20 is trying to develop rotation! T-storm warning up for it now but expect a TOR in a few min.

SPC is reporting a tornado touchdown near bradley, ar. g2g shear ~40 mi. SE of pine bluff is looking real impressive. i wouldn't be surprised to see this storm drop another tornado or two.

EDIT: TOR warn now in effect for the cell that i pointed out earlier now S of el dorado just across the state line.

numerous reports of Buildings damaged around Dumas, AR due to tornado touchdown.

the big storm appears to be weakening as it gets closer to Memphis, however, the cell SE of El Dorado looks like it could drop a tornado at any min. if it hasn't done so already.

EDIT: the cell NE of El Dorado appears to be quickly gaining a TVS. warning should be issued shortly.

I just heard a report of "cars in trees" in Dumas, AR along HWY 65, to go along with the building damage.

CNN is also reporting injuries in Dumas, though the severity or how many is unknown at this point.

I also believe I heard them say the damage path there may be as much as a half mile wide.

Unfortunately it looks like Dumas may be getting hit by a second tornado at this time. From KLZK:

...A TORNADO WARNING REMAINS IN EFFECT UNTIL 445 PM CST FOR
NORTHWESTERN DESHA COUNTY...

AT 416 PM CST...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE A TORNADO. THIS TORNADO WAS LOCATED JUST SOUTHWEST OF
DUMAS...MOVING NORTHEAST AT 45 MPH.

The storm has a very intense circulation and in all likelihood is producing a tornado. What are the odds of one town getting hit by two tornadoes within four hours of eachother?
 
Offical LSR report does indeed quote cars in trees near to Dumas.

TORNADO Feb 24 20:55 UTCDUMASDESHAARTRAINED SPOTTERRECEIVED REPORT OF CARS IN TREES NORTH OF DUMAS ON HIGHWAY 65. TIME REPORTED IS APPROXIMATE.
 
The tail end charlie storm has officially gone tornadic in Ashely County, Arkansas as of a few minutes ago:

AT 431 PM CST...THE PUBLIC REPORTED A TORNADO. THIS TORNADO WAS
LOCATED NEAR NORTH CROSSETT...MOVING NORTHEAST AT 70 MPH.

The circulation is very tight and very intense and in all likelihood this is a strong or violent tornado. It should pass over the town of Hamburg, Arkansas momentarily. I hope everyone gets to shelter in time, as this 'nader is hauling at 70 mph! It also looks like this storm may eventually affect Greenville, Mississippi in about forty five minutes. This is a very dangerous situation, to say the least.
There is also another intense couplet over central Desha County west of Rohwer, Arkansas which probably has a tornado on the ground attm.

Nader motion is not 70mph, it appears to be a met just taking the storm icon output. If you look at radar, actual motion is closer to 45-50mph. I'm not sure that you can classify this as violent based on radar returns - SRV and NROT are not too high up the scale.
 
I'm not saying the Ashely Co. tornado IS violent, just given the environment the storm is in and the fact that there's a PDS watch out with specific wording about possible significant tornadoes in the area, I'm just saying that it's possible. The SRV is still fairly impressive, so maybe not a violent tornado, but probably a strong one. Now the couplet in Desha County, on the other hand... check that out!
 
DP In West Alabama...

Dewpoints have been in the 30's and 40's across much of Alabama today, but the DP here has been moving rapidly north... We are at 52 now just after 1700. It appears that things may be heating up in West Alabama later this evening.
 
With the rain showers increasing over much of MS it would make sense that some of the tornadic potential will be on the decrease as the line moves eastward...
 
Tornado warnings now for Bolivar and Washington County, Mississippi as the supercells will cross the Mississippi River memomentarily. Cleveland and Greenville are included in the warnings. With the aforementioned shower activity in northern Mississippi, these storms should weaken as they move into the less favorable environment.

Further south, it looks like the storms on the southern end of the squall line are really beginning to get their act together. A tornado warned cell with a decent hook on base reflectivity is just northwest of Bastrop, Louisiana attm, and should cross into Arkansas in a few minutes. A very nasty severe warned supercell has exploded just west of Monroe, Louisiana and will likely become tornadic shortly. Other supercells are forming along the dryline from southwest of Monroe to northeast of Jasper, TX. The latest MD from the SPC hints that a tornado watch may be issued shortly for central and southern Louisiana given the recent convective trends, the strongly sheared environment and the fact that boundary layer moisture is increasing significantly across the area. Louisiana's undoubtedly going to have some pretty rough weather the next three to five hours as this line moves through.
