MESOSCALE DISCUSSION 1225
NWS STORM PREDICTION CENTER NORMAN OK
0616 PM CDT SUN JUN 28 2015

AREAS AFFECTED...LEE OF THE CNTRL ROCKIES

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 282316Z - 290115Z

PROBABILITY OF WATCH ISSUANCE...5 PERCENT

SUMMARY...MARGINALLY SEVERE HAIL AND LOCALLY STRONG WIND GUSTS MAY
CONTINUE TO ACCOMPANY ISOLATED TSTMS THROUGH ABOUT SUNSET.

DISCUSSION...SPORADIC TSTM DEVELOPMENT HAS OCCURRED WITHIN A PLUME
OF GENERALLY LOWER TO MIDDLE 50S SURFACE DEW POINTS AND LIGHT
UPSLOPE FLOW REGIME ACROSS THE CNTRL HIGH PLAINS. AREA VWP DATA
CONFIRM MID-LEVEL WINDS OF ONLY AROUND 20-30 KT...WITH THE BULK OF
STRONGER N/NWLYS CONFINED TO THE LOWER PLAINS. NEVERTHELESS...THE
PRESENCE OF A HIGH-LEVEL SPEED MAX IN CONJUNCTION WITH STEEP
MID-LEVEL LAPSE RATES APPEARS TO FAVOR MARGINALLY SEVERE HAIL IN THE
STRONGEST UPDRAFTS. THIS RISK SHOULD DIMINISH AFTER SUNSET OWING TO
THE LACK OF GREATER LARGE-SCALE ASCENT.
