NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jun 12, 2:12 PM EST, 3 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 312 PM EDT TUE JUN 12 2012 .SYNOPSIS... A COLD FRONT WILL MOVE SOUTHEAST AND ACROSS THE EASTERN CAROLINAS WEDNESDAY...MOVING OFFSHORE WEDNESDAY NIGHT. SHOWERS AND THUNDERSTORMS WILL END AS THE FRONT MOVES OFFSHORE. LOW PRESSURE SHOULD DEVELOP ALONG THE FRONT THURSDAY...BRINGING NORTHEAST WINDS AND MILD TEMPERATURES TO THE CAROLINAS THURSDAY INTO SATURDAY. HIGH PRESSURE WILL BUILD INTO THE AREA FROM THE NORTHEAST EARLY NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... AS OF 140 PM TUESDAY...CORRIDOR OF DEEPEST MOISTURE CONTINUES ALONG THE IMMEDIATE COAST. HEAVY RAINFALL WILL CONTINUE TO BE AN ISSUE BUT NOT WIDESPREAD ENOUGH FOR ANY WATCH...BUT SHORT FUSED ADVISORIES OR PERHAPS WARNINGS. ZONES FURTHER WEST ARE MORE PROBLEMATIC...IT IS TOUGH TO LOWER POPS TOO MUCH AS SUCH DEEP MOISTURE AND LOW LCLS ARE PRONE TO GENERATE RAIN SHOWERS WITH THE WEAKEST OF FORCING. EVEN SO...COVERAGE AND INTENSITY WILL BE LOWER COMPARED TO ALONG THE COAST AND THIS TREND HAS BEEN HEDGED TOWARDS WITH LATEST UPDATE. WILL MONITOR FOR FURTHER DOWNWARD ADJUSTMENTS OF POPS AND ESPECIALLY QPF OVER WRN ZONES OVER NEXT FEW HOURS. ALSO SPED UP TIMING OF DRYING DURING THE OVERNIGHT FROM NW TO SE. AT A FIRST APPROXIMATION THE CUTOFF OF MEASURABLE PRECIPITATION MAY FOLLOW THE 850MB WIND SHIFT...BISECTING THE REGION FROM NW TO SE BY 03Z AND ARRIVING ALONG THE COAST BY 06-07Z. THE VERY IMMEDIATE COAST MAY SEE RAIN LINGER PAST THIS TIME HOWEVER AS THOSE PLACES MAY HAVE TO WAIT FOR SURFACE FROPA TO DRY OUT COMPLETELY...WHICH IS SLATED FOR THE SHORT TERM. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... AS OF 300 PM TUESDAY...THE BAND OF DEEP TROPICAL MOISTURE WILL BEGIN TO NUDGE OFFSHORE WEDNESDAY AS THE 500 MB UPPER TROUGH BEGINS TO KICK EAST AND FINALLY OFF THE COAST WEDNESDAY NIGHT. THE SURFACE COLD FRONT WILL ACCOMPANY THE UPPER TROUGH TO THE COAST WEDNESDAY AFTERNOON...BUT A WEAK SEABREEZE WILL HOLD UP THE FRONT'S EASTWARD PROGRESS UNTIL EVENING. THE HIGHEST CHANCES FOR SHOWERS AND STORMS WEDNESDAY WILL OCCUR NEAR THE COAST WHERE ENHANCED LOW-LEVEL CONVERGENCE WILL COEXIST WITH THE LINGERING TROPICAL HIGH-PRECIPITABLE WATER ATMOSPHERE. CONVECTIVE COVERAGE SHOULD RANGE FROM 50-60 PERCENT ALONG THE COAST TO ONLY 20-30 PERCENT ALONG AND WEST OF INTERSTATE 95. UNLIKE TODAY...WEDNESDAY'S STORM MOTION SHOULD BE FROM NORTH TO SOUTH AS THE MID-LEVEL FLOW SHIFTS BEFORE THE SURFACE FRONT ARRIVES. DRIER AIR SHOULD OVERSPREAD THE REGION FROM NW TO SE WEDNESDAY NIGHT WITH MODEL PRECIP WATER VALUES DROPPING FROM ~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
