..CAROLINAS AND SOUTHEAST VIRGINIA
AT MIDDAY, TEMPERATURES CONTINUE TO WARM THROUGH THE 70S F, NEARING
80F, ACROSS THE PIEDMONT AND COASTAL PLAIN AHEAD OF A COLD FRONT, IN
THE PRESENCE OF MIDDLE 60S F DEWPOINTS. THIS WILL CONTINUE TO YIELD
WEAKENING INHIBITION AND MODEST BUOYANCY (I.E. MLCAPE AROUND
500-1000 J/KG) THIS AFTERNOON, WITH INCREASING STORM DEVELOPMENT
ANTICIPATED BY MID/LATE AFTERNOON. THE COMBINATION OF MODEST
BUOYANCY, MODERATE SHEAR, AND ASCENT ALONG AND AHEAD OF THE COLD
FRONT WILL LIKELY YIELD A FEW STRONGER, MORE ORGANIZED STORMS. GIVEN
THE STEEP LOW-LEVEL LAPSE RATES, LOCALLY STRONG OUTFLOW/DAMAGING
GUSTS ARE POSSIBLE WITHIN ANY MORE ORGANIZED AND PERSISTENT
UPDRAFTS, PARTICULARLY WITH DEVELOPMENT ACROSS THE COASTAL PLAIN.
..SOUTH TEXAS
A COUPLE OF STRONG/LOCALLY SEVERE STORMS CAPABLE OF LARGE HAIL MAY
LINGER TODAY WITHIN AN ELEVATED SUPERCELL-FAVORABLE ENVIRONMENT.
EFFECTIVE SHEAR EXCEEDS 40 KT AND ELEVATED MUCAPE IS ESTIMATED TO BE
AROUND 1000-1500 J/KG BASED ON AVAILABLE 12Z OBSERVED SOUNDINGS AND
LATEST SPC MESOANALYSIS DATA.
