Looks like another round of potentially deadly weather is on the way for the middle of the week across the same areas that just got hammered a couple of days ago. A major tornado outbreak is possible Wednesday afternoon and into the nighttime hours across eastern Texas, eastern Oklahoma, Arkansas, southern Missouri and Louisianna.
It's still early and things could change as we closer and closer to Wednesday afternoon. But as of now most forecast guidence suggests that as the upper level energy that will be responsible for creating today's severe weather along the dry line swings into Oklahoma a similar dynamic set up as to what we saw last week will develop. This means that the potential exists for thunderstorms to produce large hail, damaging winds and tornadoes. Some of these tornadoes once again may be large and very destructive.
Keep it tuned to your local news source and myweatherlive.com for the very latest on this developing severe weather situation.

Technical Severe Weather Parameters
Little Rock, Arkansas
CAPE 1211.7
LIFTED INDEX: -3.8
SWEAT INDEX: 449.7
SHOWALTER INDEX: -3.2
0-3 KM HEL: 547.2
For Little Rock its the 0-3 km Helicty values and the Sweat Index that really has me concerned. Both suggest tornadoes.
Texarkana, Texas
CAPE: 1650.9
LIFTED: -6.9
SWEAT INDEX: 498.1
SHOWALTER INDEX: -5.2
0-3km HEL: 350.9
Out of all of the reporting stations that I have looked at today for the potential of severe weather on Wednesday, Texarkana has the highest numbers. This means that this was one of the areas that not only had the greatest chance of seeing severe weather but the greatest chance of seeing the worst of it as well.
Shreveport, Louisianna
CAPE: 809.7
LIFTED INDEX: -6.7
SWEAT INDEX: 465.5
SHOWALTER INDEX: -4.2
0-3 KM HEL: 501.6
The numbers look pretty impressive for Shreveport Louisianna on Wednesday evening as well.
Once again its the SWEAT and the Helicity numbers that have me concerned as they're both well within tornado range. Surface instability is running very high as both the Showalter and Lifted Indicies are -4.2 and -6.7 respectfully.
