VALID 301200Z - 011200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS PORTIONS OF
NORTH-CENTRAL TEXAS INTO SOUTHERN OKLAHOMA...
..SUMMARY
WIDELY SCATTERED THUNDERSTORM ACTIVITY IS EXPECTED FROM THE SOUTHERN
PLAINS TO THE GREAT LAKES ON WEDNESDAY AS A MID-LEVEL TROUGH EJECTS
INTO THE SOUTHERN PLAINS. SEVERE THUNDERSTORMS WILL BE POSSIBLE
ACROSS EAST-CENTRAL TEXAS INTO CENTRAL/EASTERN OKLAHOMA.
..SYNOPSIS
A MID-LEVEL TROUGH WILL EJECT ACROSS THE SOUTHERN PLAINS ON TUESDAY.
SURFACE LOW DEVELOPMENT IS EXPECTED ACROSS WESTERN TEXAS ON
D2-TUESDAY, WITH A WEAK LOW TRACKING EASTWARD INTO EAST-CENTRAL
TEXAS BY THE D3-WEDNESDAY PERIOD. OVERNIGHT THUNDERSTORM ACTIVITY IS
EXPECTED AT THE BEGINNING OF THE D3 PERIOD ACROSS PORTIONS OF
CENTRAL OKLAHOMA INTO EAST-CENTRAL TEXAS. BY THE AFTERNOON,
ADDITIONAL SCATTERED THUNDERSTORM DEVELOPMENT ALONG THE DRYLINE NEAR
THE RED RIVER ON WEDNESDAY AFTERNOON WILL POSE POTENTIAL FOR SEVERE
WIND, HAIL, AND A TORNADO.
..EAST-CENTRAL TEXAS INTO SOUTHERN OKLAHOMA
SCATTERED THUNDERSTORM DEVELOPMENT ALONG THE DRYLINE ACROSS CENTRAL
TEXAS INTO OKLAHOMA ON THURSDAY AFTERNOON WILL POSE SOME SEVERE
POTENTIAL. SOME UNCERTAINTY ARISES IN COVERAGE OF MORNING CONVECTION
AND CLOUD COVER. HOWEVER, IT APPEARS A CORRIDOR OF FAVORABLE
INSTABILITY AND SHEAR WILL OVERLAP BY THE AFTERNOON ALONG AND AHEAD
OF THE DRYLINE. SHEAR PROFILES WILL BE SUPPORTIVE OF SUPERCELLS
BEFORE CLUSTERS BEGIN TO FORM AND ATTEMPTS AT UPSCALE GROWTH OCCUR.
LARGE HAIL AND DAMAGING WIND WILL BE THE PRIMARY RISKS GIVEN STEEP
LAPSE RATES, THOUGH FORECAST SOUNDINGS DO SHOW SOME CURVATURE OF LOW
LEVEL HODOGRAPHS FAVORABLE FOR SOME TORNADO RISK WITH EARLY
SUPERCELL MODES.
