..DISCUSSION
..DAY 4/THU
SOME LOW-END SEVERE THUNDERSTORM RISK COULD PERSIST INTO DAY 4/THU
ACROSS PORTIONS OF THE SOUTHEAST AS AN UPPER TROUGH PIVOTS TOWARD
THE ATLANTIC COAST IN TANDEM WITH AN EASTWARD-ADVANCING SURFACE COLD
FRONT. AHEAD OF THE FRONT, A MOIST AIRMASS WILL BE IN PLACE FROM
GA/FL NORTHEAST TOWARD SOUTHEAST VA. CONVECTION WILL LIKELY BE
ONGOING THURSDAY MORNING, AND PERSISTENT WARM ADVECTION WILL RESULT
IN WIDESPREAD CLOUDINESS. THIS WILL LIMIT DESTABILIZATION AND LAPSE
RATES ARE EXPECTED TO REMAIN MODEST. OVERALL, SEVERE POTENTIAL
APPEARS LESS THAN 15 PERCENT.
..DAYS 5-8/FRI-MON
SEVERE THUNDERSTORM POTENTIAL APPEARS LOW FRIDAY AND SATURDAY AS A
PRIOR COLD FRONTAL PASSAGE INTO THE GULF LEAVES A DEARTH OF BOUNDARY
LAYER MOISTURE IN ITS WAKE. ANOTHER UPPER TROUGH IS EXPECTED TO
DEEPEN OVER THE PLAINS AND THE EASTERN U.S. LATE IN THE PERIOD. SOME
MOISTURE RETURN MAY OCCUR AHEAD OF THIS FEATURE BEFORE ANOTHER COLD
FRONT DEVELOPS SOUTHEAST ACROSS THE EASTERN HALF OF THE CONUS. THIS
COULD BRING SOME INCREASING THUNDERSTORM POTENTIAL TO PARTS OF THE
SOUTH-CENTRAL OR SOUTHEAST U.S., HOWEVER, AT THIS TIME ANY BETTER
MOISTURE RETURN LOOKS DISPLACED TO THE SOUTH OF STRONGER FLOW ALOFT.
