AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
848 PM CDT WED MAY 7 2014

.UPDATE...
SEVERE WEATHER THREAT THIS EVENING... UPDATED POPS/WX/TEMPS

&&

.DISCUSSION...
QUICK EVENING UPDATE... STORMS CONTINUE DEVELOP ACROSS PORTIONS OF
WRN AND CENTRAL OKLAHOMA AND WESTERN NORTH TEXAS. THE DRYLINE HAS
STARTED TO RETREAT... WITH 01Z SFC ANALYSIS PLACING IT SOMEWHERE
NEAR THE OK/TX PH BORDER. DEW POINTS HAVE RECOVERED NICELY...
WITH BUFKIT PROFILES CONTINUING TO SHOW A DECENT ENVIRONMENT
ACROSS SWRN OK AND WRN N TX... 0-6KM SHEAR OF 30 TO 45KTS... AND
1000 TO 1700 J/KG SBCAPE. AS STORM MOVE EAST... THEY WILL START TO
MOVE INTO A SLIGHTLY LESS FAVORABLE ENVIRONMENT FOR SFC BASED
STORMS... AS 08/00Z OPERATIONAL SOUNDING FROM KOUN STILL SHOWS A
SIZABLE EML BETWEEN 850-800MB. HOWEVER... SFC BASED MOISTURE IS
GOOD... WITH A GOOD ISENTROPIC RESPONSE IN THE BL. BUFR SOUNDINGS
FROM OKC SHOWS THE EML WEAKENING... AND COMBINED WITH THE
INCREASED LLJ OVERNIGHT AS THE H500 TROUGH DIGS FURTHER E/SE
ACROSS THE ROCKIES... EXPECT A ROUND TWO OF CONVECTION ACROSS THE
REGION TO PICK UP NEAR/AFTER MIDNIGHT CONTINUING THROUGH THE
MORNING. EXPECT A LINEAR/COMPLEX TO EVOLVE THROUGH THE EARLYTHURSDAY
MORNING HOURS CONSIDERING DECENT 1500 TO 1800 SFC-500 MUCAPE AND
0-3KM SHEAR OF 30 TO 40 KTS AHEAD OF A WEAK SFC TROUGH NUDGING
EASTWARD. THE SEVERE THREAT WILL LESSEN OVERNIGHT... BUT IF
CLUSTERS ARE ABLE TO DEVELOP ANY SIZABLE COLD POOLS... THERE COULD
BE A WIND THREAT OVERNIGHT.
