NWS Charleston, SC wrote its last area forecast discussion before the first event at Jun 11, 3:04 PM EST, 3 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 404 PM EDT WED JUN 11 2014 .SYNOPSIS... A TROUGH OF LOW PRESSURE WILL REMAIN OVER THE SOUTHEAST STATES THROUGH EARLY NEXT WEEK BEFORE HIGH PRESSURE REBUILDS OVER THE WESTERN ATLANTIC. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... SHORTWAVE ENERGY AND ABUNDANT MOISTURE CONTINUES TO ADVECT FROM THE GULF OF MEXICO AND CARIBBEAN INTO THE EASTERN UNITED STATES ALONG THE PERIPHERY OF AN UPPER TROUGH AXIS. THIS PATTERN HAS SUPPORTED WIDESPREAD THUNDERSTORMS ACROSS SOUTH CAROLINA AND GEORGIA THIS AFTERNOON. ALTHOUGH THE SEABREEZE HAS ONLY SPAWNED ISOLATED ACTIVITY ACROSS SOUTHEAST SOUTH CAROLINA ZONES...SCATTERED TO NUMEROUS THUNDERSTORMS HAVE STEADILY PROGRESSED NORTHWARD INTO THE GEORGIA COUNTIES DURING THE PAST FEW HOURS. LATEST TRENDS SUGGEST THAT THIS LINE OF CONVECTION WILL STEADILY SHIFT NORTHWARD...LIKELY INTERACTING WITH ANOTHER LINE OF ACTIVITY FARTHER INLAND AND ANY ISOLATED SEABREEZE STORMS TO THE NORTH. HOT AND HUMID CONDITIONS HAVE SUPPORTED AMPLE INSTABILITY...AND WITH WAVES OF UPPER LEVEL ENERGY MOVING INTO THE REGION DOWNSTREAM OF THE TROUGH AXIS...EXPECT THE POTENTIAL FOR ISOLATED THUNDERSTORMS TO INTENSIFY AND BECOME SEVERE FOR ANOTHER FEW HOURS. MAIN HAZARDS WITH ORGANIZED/STRONG CONVECTION WILL BE DAMAGING WIND GUSTS AND LARGE HAIL. SURFACE OBSERVATIONS IN THE WAKE OF THUNDERSTORMS INDICATE NOTABLE COOLING AND STABILIZATION...AND THUS EXPECT THE SEVERE POTENTIAL TO DIMINISH LATER THIS EVENING. HAVE INDICATED HIGHEST CONVECTIVE COVERAGE FOR THE NEXT SEVERAL HOURS...HAVE THEN ADVERTISED RAIN CHANCES DIMINISHING LATER THIS EVENING. CONSIDERING THAT THE APPROACHING UPPER TROUGH WILL MAINTAIN DECENT DIVERGENCE ACROSS THE SOUTHEAST STATES...WHILE SHORTWAVE ENERGY CONTINUES TO TRACK THROUGH THE REGION...AT LEAST ISOLATED SHOWERS/THUNDERSTORMS COULD LINGER OVERNIGHT. VARIABLE SKY COVERAGE IS EXPECTED OVERNIGHT...INCLUDING LINGERING DEBRIS CLOUDS FROM CONVECTION. LOW TEMPERATURES WILL RANGE FROM AROUND 69 DEGREES FAR INLAND TO THE LOW 70S CLOSER TO THE COAST. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... THURSDAY...A HIGH AMPLITUDE MID LVL TROUGH OF LOW PRESSURE CURRENTLY DEPICTED TO OUR WEST ON WATER VAPOR IMAGERY WILL GRADUALLY SHIFT EAST TOWARD THE AREA BUT REMAIN INLAND THROUGH THE DAY. THE PATTERN WILL RESULT IN A DEEP SOUTHWEST FLOW OVER MUCH OF THE SOUTHEAST AND A PINNING OF THE SEABREEZE ALONG THE COAST UNTIL LATE AFTERNOON. ALTHOUGH PRECIP ACTIVITY WILL LIKELY HOLD OFF THROUGH AT LEAST LATE MORNING...INCREASED FORCING FROM THE APPROACHING TROUGH ALONG WITH PWATS NEAR 1.5 INCHES SHOULD SUPPORT AT LEAST A SLIGHT CHANCE TO CHANCE OF SHOWERS AND/OR THUNDERSTORMS DURING PEAK HEATING THURSDAY AFTERNOON. OVERALL HIGH TEMPS ARE EXPECTED TO RANGE IN THE UPPER 80S TO LOWER 90S AWAY FROM THE COAST. ALTHOUGH AN ISOLATED STRONGER THUNDERSTORM IS POSSIBLE...POOR MID LVL LAPSE RATES AND WEAK SHEAR WILL LIKELY RESULT IN PULSE TYPE THUNDERSTORMS. OVERNIGHT LOWS SHOULD RANGE IN THE UPPER 60S INLAND TO LOW/MID 70S NEAR THE COAST. FRIDAY...THE MID LVL TROUGH WILL EXTEND ACROSS THE SOUTHEAST EARLY...BEFORE SHIFTING OFFSHORE DURING THE AFTERNOON/EVENING. DESPITE THE CONTINUATION OF A SOUTHWEST FLOW OVER THE AREA...DEEPER MOISTURE AND INCREASED FORCING FROM THE TROUGH WILL LIKELY RESULT IN CHANCES OF SHOWERS AND/OR THUNDERSTORMS OVER MOST AREAS FRIDAY AFTERNOON. A FEW PULSE TYPE THUNDERSTORMS COULD BE STRONG...BUT THE OVERALL THREAT OF SEVERE WEATHER SHOULD REMAIN LOW GIVEN WEAK SHEAR AND POOR MID LVL LAPSE RATES. THE SEABREEZE SHOULD ONCE AGAIN REMAIN PINNED ALONG THE COAST UNTIL LATE AFTERNOON/EARLY EVENING AND COULD PROVIDE ADDITIONAL SHOWER AND/OR THUNDERSTORM COVERAGE THROUGH EVENING HOURS. OVERALL HIGHS SHOULD RANGE IN THE UPPER 80S TO AROUND 90 OVER INLAND AREAS. OVERNIGHT LOWS WILL RANGE IN THE UPPER 60S INLAND TO LOW/MID 70S ALONG THE COAST. SATURDAY...THE MID LVL TROUGH WILL SHIFT FURTHER OFFSHORE OVER THE WESTERN ATLANTIC...WHILE WEAK SFC HIGH PRESSURE GRADUALLY EXTENDS OVER THE REGION FROM THE NORTH/NORTHWEST. ALTHOUGH THE MAIN WAVE OF LOW PRESSURE WILL BE POSITIONED WELL OFFSHORE...MODELS SUGGEST THAT A WEAK MID LVL LOW WILL LINGER OVER THE SOUTHEAST AND BECOME NEARLY CUTOFF IN A BROAD RIDGE OF HIGH PRESSURE. GIVEN THE LINGERING MID LVL LOW AND PWATS STILL BETWEEN 1.5 TO 1.75 INCHES...A SLIGHT CHANCE TO CHANCE OF SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE...ESPECIALLY DURING PEAK HEATING ALONG AN INLAND MOVING SEABREEZE. OVERALL HIGH TEMPS SHOULD BE AROUND 90 DEGREES...WARMEST INLAND. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE REMNANTS OF THE UPPER TROUGH WILL LIFT OUT OF THE AREA SATURDAY NIGHT AND SUNDAY...WITH UPPER RIDGING DURING THE EARLY TO MIDDLE PART OF NEXT WEEK. THE INFLUENCE OF THE UPPER TROUGH ON SUNDAY COULD ALLOW FOR SLIGHTLY BETTER DAYTIME CONVECTIVE COVERAGE BEFORE WE RETURN TO A MORE ISOLATED SHOWER/TSTM PATTERN MONDAY THROUGH WEDNESDAY. HIGHS WILL BE IN THE LOWER 90S AND LOWS IN THE LOWER 70S. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... THUNDERSTORM ACTIVITY WILL CONTINUE TO SPREAD NORTHWARD LATE THIS AFTERNOON...AND HAVE THUS MAINTAINED MENTION OF AT LEAST VCTS AT BOTH TERMINALS THROUGH THE EVENING HOURS. CONSIDERING ONGOING CONVECTION AT KSAV BY 19Z...HAVE BEEN MORE DETERMINISTIC WITH TSRA AND REDUCED VSBYS/CIGS. WILL NEED TO WAIT UNTIL TRENDS BECOME MORE CLEAR BEFORE ADDING SPECIFIC MENTION OF TSRA TO THE KCHS FORECAST...ESPECIALLY SINCE SEABREEZE CONVECTION COULD BE DELAYED UNTIL THE BOUNDARY IS WEST OF THE TERMINAL. TEMPORARY REDUCTIONS IN CEILINGS/VISIBILITIES AND ERRATIC/GUSTY WINDS ARE POSSIBLE WITH ANY THUNDERSTORMS...AS IS EXCESSIVE LIGHTNING. SHOWER/THUNDERSTORM POTENTIAL IS EXPECTED TO DECREASE DURING THE EVENING AND OVERNIGHT HOURS. EXTENDED AVIATION OUTLOOK...MODERATE RISK FOR BRIEF FLIGHT RESTRICTIONS AT EITHER TERMINAL EACH AFTERNOON/EARLY EVE DUE TO SHOWERS/THUNDERSTORMS. && .MARINE... TODAY THROUGH MONDAY...WINDS/SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS AS ATLANTIC HIGH PRESSURE DOMINATES THE PATTERN OVER THE COASTAL WATERS. IN GENERAL...SOUTH TO SOUTHWEST WINDS WILL REMAIN AT OR BELOW 15 TO 20 KT...HIGHEST ALONG THE COAST DURING AFTERNOON SEABREEZE CIRCULATIONS INTO EARLY WEEKEND. SEAS WILL BE NO GREATER THAN 3 TO 4 FT...HIGHEST FRIDAY NIGHT INTO EARLY SATURDAY BEYOND 20 NM FROM THE COAST. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE.
