We're still looking at a Slight Risk for tomorrow:
DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1210 AM CDT SUN APR 26 2015
VALID 271200Z - 281200Z
...THERE IS A SLGT RISK OF SVR TSTMS FROM NCNTRL TX TO THE CNTRL
GULF COAST...
...THERE IS A MRGL RISK OF SVR TSTMS IMMEDIATELY SURROUNDING THE
SLGT RISK...
...SUMMARY...
SCATTERED SEVERE THUNDERSTORMS WILL DEVELOP FROM NORTH CENTRAL TEXAS
TO THE CENTRAL GULF COAST DURING THE DAY2 PERIOD.
...TX TO CNTRL GULF COAST...
STRONG MID-LEVEL SPEED MAX IS FORECAST TO DIG SEWD ACROSS THE LOWER
CO RIVER VALLEY INTO NRN MEXICO BEFORE EJECTING EWD INTO THE EDWARDS
PLATEAU DURING THE LATTER HALF OF THE DAY1 PERIOD. EXIT REGION OF
THIS JET WILL OVERSPREAD THE DRY LINE ACROSS WCNTRL TX AND
PRONOUNCED DIFLUENT HIGH-LEVEL FLOW WILL ENCOURAGE WIDESPREAD
CONVECTION ACROSS THE SRN PLAINS LATE SUNDAY...ESPECIALLY NORTH OF
SYNOPTIC COLD FRONT. NRN EDGE OF SEVERE THREAT WILL BE GREATLY
INFLUENCED BY POSITION OF COLD FRONT/EFFECTIVE BOUNDARY THAT SHOULD
BE DRAPED ACROSS NCNTRL TX AT DAYBREAK MONDAY. THERE IS SOME
CONCERN THAT GREATEST BUOYANCY MAY BE DISPLACED A BIT FARTHER SOUTH
THAN LATEST NAM SUGGESTS. AS UPPER LOW DRIFTS EWD ACROSS THE SRN
PLAINS IT APPEARS THE STRONGEST BOUNDARY LAYER HEATING WILL BE
OBSERVED ACROSS SWRN INTO CNTRL TX MONDAY AFTERNOON...JUST WEST OF
SFC FRONT/DRY LINE.
EARLY IN THE PERIOD...THUNDERSTORMS SHOULD BE ONGOING ACROSS MUCH OF
OK WITHIN STRONG WARM ADVECTION REGIME. THIS ACTIVITY SHOULD
SPREAD/DEVELOP SEWD INTO THE WARM SECTOR BY MID DAY AS CONVECTIVE
INHIBITION SHOULD BE NEGLIGIBLE ACROSS THIS REGION. STRONG
DEEP-LAYER SHEAR WILL PROVE SUPPORTIVE FOR ORGANIZED STORMS AND
ISOLATED SUPERCELLS ARE CERTAINLY POSSIBLE...THOUGH STORM MERGERS
AND CLUSTERS APPEAR LIKELY GIVEN THE WIDESPREAD CONVECTIVE COVERAGE.
LARGE HAIL...DAMAGING WINDS...AND PERHAPS A FEW TORNADOES CAN BE
EXPECTED WITH TSTMS THAT EVOLVE ACROSS TX DURING THE DAY. ACTIVITY
THAT DEVELOPS ALONG THE CNTRL GULF COAST WILL DO SO WITHIN A WEAKER
LAPSE RATE ENVIRONMENT AND HAIL SHOULD GENERALLY BE SUB-SEVERE.
