May 28th Severe Weather Potential

Temperatures once again are going to be on the warm to hot side with temperatures in the 70s to 90s depending on where you live. Taking a look at what we expect current conditions to be like in the morning ...
We have an area of low pressure over Kansas attached to a cold front,, A low pressure back over Western Iowa where the front turns more stationary. A dry line from the Ok /TX panhandle southwest to south into West TX. Once again storms could fire along this dryline . We expect all modes of severe weather possible today from strong winds to Large Hail and Tornado potential but we will show you where we think tornado potential will be..

Looking at the severe weather parameters that will be in place ..
Convective Available Potential Energy will be from 1000-4000 depending on where you are located.
Plenty of lift in the atmosphere with the index as low as negative 12...

Wind shear will be 40-50 knots across the region which is sufficient enough for severe weather to occur.
Dewpoints once again will be in the 60s and 70s across the vast majority of the region..
Now looking at the tornado parameters we see that the EHI is kind of on the high side across NE OK , All of Kansas  into SE Nebraska east over into Missouri and central Illinois. We also see that the SWEAT Index is generally high in these same areas
And the Helicity index is at 250 or above across this general area as well..
So with that said we expect the tornado potential to be located in the areas we mention above ..if outside those areas then the main threat would be winds and hail.
In reference to TX we have included the area due to parameters ..however..with the exception of west TX..the rest of TX seems to be under a CAP..
So with all the parameters out of the way this is the outlook we have put together on where you can expect the severe weather to occur..
