May 25th Severe Weather Potential


The above severe weather outlook is brought to you by Real Wx Services! The above outlook is based on a blend of the NAM/SREF (latest runs)

CAPE is anywhere from 500-5000 depending on where you reside.
Lift index is 0 to -8 depending on your location
SWEAT index is below. Instead of describing where the greatest values are with this particular day & event it will be much more easier to show the image and anywhere where you see values of 400 or greater would be potential for tornados.





EHI is also below

With EHI anything above 1 is tornadic potential . So based on the EHI you can see locations like western KY (Elizabeth a shout out to you because this is your area) Western TN (Lyndsey this is your area so a shout out to you) . Along with the Tornado potential will exist winds in excess of 60 MPH and large hail.
Residents in western Pa , (Jen Metz this is a shout out to you) look like the most that they would be dealing with is the potential for strong winds in excess of 60 MPH and the possibility of hail. If the GFS is correct there could be some tornado warnings issued but because it is a lower resolution model and not a high res model if there would be any tornado's the probability would be low and it would be very isolated.
All indications are that we are going to be looking at another widespread outlook across the Southeast into the Southwest.

Weather Synopsis

A potent shortwave trough is in the process of deepening and ejecting into the southern and central plains. Meanwhile by 00z this evening there will be a deep area of low pressure over south central KS. Guidance is in agreement on this area of low pressure developing and the deepening of the upper level low. This will cause a warm southerly flow out and ahead of the advancing cold front.
By 00z low pressure over KS will have moved off towards the east along with the cold front and by this time the cold front should have gone thru the central Part of Tx. Spreading severe chances into the NE part of TX. The low pressure will be situated at that time over NW MO and another low pressure over NW indiana.

Summary we are expecting tomorrow to be a widespread severe outbreak and would not be surprised to see the moderate area that SPC has replaced with an area of high risk. It should be a very busy day!
Stay tuned for more information and stay tuned to your media outlets!
