...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
THE CAROLINAS...
..SUMMARY
ISOLATED SEVERE STORMS MAY DEVELOP ON WEDNESDAY ACROSS PARTS OF THE
CAROLINAS, POSING A RISK FOR SEVERE WIND GUSTS.
..CAROLINAS
A LARGE MID-LEVEL TROUGH WILL ADVANCE EAST AND START TO OVERSPREAD
THE APPALACHIANS ON WEDNESDAY. LEE TROUGHING WILL SHARPEN THE
SURFACE COLD FRONT AS IT MOVES ACROSS THE CAROLINAS. DEWPOINTS ARE
EXPECTED TO BE IN THE MID 60S AHEAD OF THIS FRONT AS FAR NORTH AS
SOUTHERN/CENTRAL NORTH CAROLINA WHICH, WHEN COMBINED WITH SOME WEAK
SURFACE HEATING, SHOULD RESULT IN MODEST DESTABILIZATION. MID-LEVEL
FLOW WILL STRENGTHEN TO AROUND 50 KNOTS BY 00Z WHICH WILL LEAD TO
STRONG SHEAR AND THE POTENTIAL FOR A FEW ORGANIZED STORMS ALONG THE
FRONT DURING THE AFTERNOON. DAMAGING WIND GUSTS WILL BE THE PRIMARY
THREAT GIVEN THE VEERED LOW-LEVEL FLOW AND ONLY MODEST INSTABILITY.
..PACIFIC NORTHWEST COAST
A FEW STRONG STORMS ARE POSSIBLE EARLY WEDNESDAY ACROSS THE PACIFIC
NORTHWEST COAST AS COLD AIR OVERSPREADS RELATIVELY WARM OCEAN
WATERS. THE GREATEST INSTABILITY WILL BE DURING THE MORNING TO EARLY
AFTERNOON WHEN SOME STRONGER STORMS COULD HAVE GUSTY WINDS ALONG THE
COAST.
