Day 4 The Outbreak Continues On Tuesday

The severe weather outbreak will continue today, Tuesday with the threat moving more to the east and still across the south central part of the USA. Once again all three severe modes are anticipated to occur with the worst being from East Central TX up thru Arkansas where the greatest threat of Tornado's will be... 
The culprit will continue to be a slow moving trough and cold front moving from the west to the east and southeast..

Stationary front across the NE portion of the US will be the focal point for potentially some severe weather but in that region we only expect some winds and hail. 
Further south low pressure over TX /OK border with cold front turning northwards to a low pressure up over Wisconsin. 
So lets take a look at the severe weather parameters that will be in place. Starting with the temperatures which will be in the 70s and 80s ..

Convective Available Potential Energy will be on the range of 1000 + 

Lift Index will be in place but not as negative as previous days with about -8 being the lowest but this is still ample for severe weather..

One thing that is a little bit different today then the previous couple days is that the shear is more marginal with the exception of East East Central TX. 30 -40 knots elsewhere but up to 70 knots in East Central Tx..

Perhaps again the most alarming parameter will be the Energy Helicity Index that will be in place first starting in East Central Tx..

Then as the night goes along spreading into Arkansas..

So do to this EHI being on the high side we are anticipating this to be the greatest area for Tornadic activity. In addition large Hail and damaging winds.
Elsewhere the severe threats will be strong gusty winds along with the potential for Large Hail.

Once again if you are in the areas anticipating a moderate risk and tornados..stay tuned to your National Wx Service and we will be monitoring things all day on our weather page
