..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE POSSIBLE OVER SOUTHEAST TEXAS INTO LOUISIANA ON
WEDNESDAY INTO EARLY THURSDAY MORNING. SEVERE STORMS APPEAR
UNLIKELY.
..SYNOPSIS
PROGRESSIVE MID-LEVEL FLOW WILL AMPLIFY AND PERSIST OVER THE US
WEDNESDAY AS BROAD TROUGHING INTENSIFIES OVER THE EAST. WEAK RIDGING
OVER THE CENTRAL US WILL BE ENHANCED BY AN UPSTREAM TROUGH OVER THE
ROCKIES AND GREAT BASIN MOVING TOWARD THE PLAINS INTO EARLY
THURSDAY. AT THE SURFACE, A COLD AND DRY AIR MASS IS EXPECTED OVER
MUCH OF THE COUNTRY IN THE WAKE OF A PRIOR FRONTAL PASSAGE. THIS
FRONT WILL CONTINUE SOUTH OVER MUCH OF THE GULF AND OFF THE COAST OF
THE ATLANTIC, AS A SECOND ARCTIC FRONT MOVES SOUTH OVER THE CENTRAL
US.
THE ONLY EXCEPTION TO WIDESPREAD OFFSHORE FLOW WILL BE ACROSS
PORTIONS OF THE WESTERN GULF WHERE THE FRONT WILL STALL NEAR THE
TX/LA COASTS. AHEAD OF THE SECOND UPPER TROUGH, WARM-AIR ADVECTION
WILL SUPPORT SOME SOUTHERLY FLOW ALONG THE COAST AS A WEAK SURFACE
WAVE DEVELOPS OVER THE GULF. WEAK ELEVATED BUOYANCY AND ASCENT WILL
SUPPORT THUNDERSTORM DEVELOPMENT ACROSS PORTIONS OF SOUTHEAST TX AND
SOUTHERN LA WEDNESDAY AFTERNOON/EVENING INTO EARLY THURSDAY MORNING.
A STRONGER ELEVATED STORM OR TWO WITH SMALL HAIL IS POSSIBLE EARLY
THURSDAY, BUT GIVEN THE LIMITED BUOYANCY, A SUSTAINED SEVERE RISK
APPEARS UNLIKELY.
