.CNTRL/SRN HI PLNS TO MID MO VLY...
CONTINUED EWD MOTION OF OH VLY TROUGH WILL ALLOW UPR RDG TO REBOUND
OVER THE SRN/CNTRL RCKYS TODAY. THIS FACT...AND EXISTING
EML...CASTS SOME UNCERTAINTY REGARDING POTENTIAL FOR LATE AFTN/EVE
STORM ALONG LEE TROUGH OVER THE CNTRL HI PLNS INTO THE OK/TX
PANHANDLES. NEVERTHELESS PRESENCE OF PREVIOUSLY-MENTIONED WY
IMPULSE WITH UNIMPEDED HEATING AND SUSTAINED CONVERGENCE ALONG LEE
TROUGH SHOULD BE SUFFICIENT FOR AT LEAST ISOLD STORMS.
MODERATE INSTABILITY /SBCAPE TO 2000 J PER KG/ WILL DEVELOP ALONG
LEE TROUGH AS LIGHT SSELY LOW LVL FLOW MAINTAINS SFC DEWPOINTS IN
THE 50S TO LOW 60S F. 25-30 KT NNWLY MID LVL FLOW IS FORECAST OVER
REGION ON NE SIDE OF SRN RCKYS RDG...RESULTING IN HODOGRAPHS WITH
AMPLE DEEP SHEAR AND LOW LVL TURNING FOR ORGANIZED/ROTATING STORMS
WITH HAIL AND LOCALLY DMGG WIND.
THE THREAT FOR HAIL MAY REDEVELOP NEWD INTO PARTS OF NEB LATER
TONIGHT/EARLY THU AS LLJ STRENGTHENS AND VEERS IN RESPONSE TO
CONTINUED EWD MOVEMENT OF WY IMPULSE. ALTHOUGH AMPLE MOISTURE AND
ELEVATED INSTABILITY SHOULD BE PRESENT FOR ISOLD SVR HAIL...WEAK
CLOUD LAYER SHEAR SHOULD LIMITED STORM INTENSITY/LONGEVITY.
