..SYNOPSIS AND DISCUSSION
MEAN LONGWAVE TROUGHING WILL REMAIN OVER THE EASTERN COUNS TODAY,
WHILE A WEAK MID-LEVEL SHORTWAVE TROUGH ADVANCES EASTWARD ACROSS THE
GULF TOWARDS THE FL PENINSULA BY LATE TONIGHT. AT THE SURFACE, HIGH
PRESSURE CENTERED OVER THE SOUTHERN PLAINS TO TN/OH VALLEYS WILL
MAINTAIN OFFSHORE LOW-LEVEL TRAJECTORIES AND LIMITED LOW-LEVEL
MOISTURE OVER A LARGE MAJORITY OF THE CONUS. STILL, ISOLATED
LIGHTNING FLASHES MAY OCCUR TODAY ACROSS PARTS OF THE EASTERN GREAT
LAKES, SOUTHWEST, AND PACIFIC NORTHWEST IN ASSOCIATION WITH WEAK
MID-LEVEL PERTURBATIONS AMID THE PRESENCE OF SUFFICIENT MUCAPE AND
MODEST LIFT.
GREATER LOW-LEVEL MOISTURE (MID 60S TO LOW 70S SURFACE DEWPOINTS)
WILL REMAIN CONFINED ALONG/SOUTH OF A COLD FRONT DRAPED ACROSS THE
CENTRAL FL PENINSULA. ISOLATED TO SCATTERED THUNDERSTORMS ARE
EXPECTED TO DEVELOP THIS AFTERNOON ACROSS CENTRAL/SOUTH FL AS
DAYTIME HEATING ERODES LINGERING MLCIN, ESPECIALLY ACROSS INTERIOR
AREAS. WITH THE LOW-AMPLITUDE SHORTWAVE TROUGH REMAINING WELL TO THE
WEST OVER THE GULF THROUGH THE DAY, WEAK LOW/MID-LEVEL WINDS AND
MEAGER DEEP-LAYER SHEAR OVER LAND WILL LIKELY LIMIT UPDRAFT
ORGANIZATION AND SEVERE POTENTIAL. STILL, OCCASIONAL STRONG/GUSTY
DOWNBURST WINDS MAY OCCUR WITH THE MORE ROBUST CORES AS LOW-LEVEL
LAPSE RATES BECOME STEEPENED WITH CONTINUED DIURNAL HEATING.
