...SYNOPSIS...
A MORE ZONAL FLOW FIELD ALOFT IS FORECAST TO EVOLVE ACROSS MOST OF
THE U.S. DURING THIS PERIOD...AS A TROUGH PROGRESSING ACROSS THE ERN
STATES MOVES OFFSHORE THROUGH THE SECOND HALF OF THE PERIOD. AN
ASSOCIATED/EWD-MOVING COLD FRONT SHOULD LINGER ONSHORE OVER THE
SOUTHEAST U.S. AND WWD ACROSS THE GULF COAST REGION INTO TX...WHICH
SHOULD FOCUS DEVELOPMENT OF AFTERNOON SHOWERS AND THUNDERSTORMS.
ELSEWHERE...APPRECIABLE DEEP MOIST CONVECTION IS NOT ANTICIPATED.
...THE SOUTHEAST...
MODEST AFTERNOON DESTABILIZATION ACROSS THE SERN U.S. IS FORECAST
AHEAD OF THE ADVANCING COLD FRONT...WHICH WILL SUPPORT A DIURNAL
INCREASE IN CONVECTION. WITH THE DEGREE OF DESTABILIZATION LIKELY
TO BE LIMITED AND WITH THE STRONGER LARGE-SCALE UVV ASSOCIATED WITH
THE UPPER TROUGH TO REMAIN FARTHER N...WIDESPREAD SEVERE THREAT IS
NOT EXPECTED. HOWEVER...WITH 25 TO 35 KT WLYS AT MID-LEVELS
FORECAST ACROSS THE CAROLINAS AND VICINITY DURING THE AFTERNOON...A
STRONGER STORM OR TWO NEAR PEAK HEATING COULD PRODUCE
MARGINALLY-SEVERE HAIL AND/OR GUSTY WINDS.
