...SYNOPSIS/FORECAST...
A BROAD...CYCLONIC FLOW REGIME WILL BE MAINTAINED OVER THE CONUS
THROUGH THE D1 PERIOD. EMBEDDED WITHIN THIS PATTERN...A STRONG
SHORT-WAVE TROUGH OVER THE SRN PLAINS IS FORECAST TO DEAMPLIFY WHILE
TRANSLATING THROUGH THE GULF STATES AND SERN U.S. AT THE
SURFACE...LOW-LEVEL MASS RESPONSE TO ABOVE-MENTIONED SHORT-WAVE
TROUGH WILL RESULT IN THE NWD ADVECTION OF A MARITIME AIR MASS
THROUGH THE ERN GULF OF MEXICO AND FL...MARKED BY BOUNDARY LAYER DEW
POINTS IN THE 60S. WHILE ISOLATED LIGHTNING STRIKES WILL BE
POSSIBLE WITHIN WAA REGIME OVER NRN FL LATE TONIGHT INTO THU
MORNING...IT APPEARS THAT WEAK MIDLEVEL LAPSE RATES WILL LIMIT
PARCEL BUOYANCY DEPTH AND THE POTENTIAL FOR MORE ROBUST TSTM
DEVELOPMENT. ELSEWHERE...A DRY...STATICALLY STABLE ENVIRONMENT WILL
PREVAIL.
