NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jul 9, 1:44 PM EST, 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 244 PM EDT SAT JUL 9 2011 .SYNOPSIS... TROPICAL MOISTURE OVER THE EASTERN CAROLINAS WILL LEAD TO SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING. A WEAK COLD FRONT WILL MOVE THROUGH FROM THE NORTH LATE TODAY...STALLING OFF THE SOUTH CAROLINA COAST SUNDAY AND THEN DISSIPATING. BERMUDA HIGH PRESSURE WILL BUILD BACK ACROSS THE AREA EARLY NEXT WEEK. ANOTHER COLD FRONT MAY APPROACH THE AREA DURING THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... AS OF 2PM SATURDAY...WEAK COLD FRONT HAS MOVED INTO THE AREA...EXTENDING FROM NORTHERN PENDER COUNTY WEST THROUGH NORTHERN MARLBORO COUNTY. THE FRONT WILL SLOWLY SAG SOUTH DURING THE AFTERNOON...WITH SHOWERS AND THUNDERSTORMS POPPING UP AHEAD OF IT. CURRENTLY THE BEST ACTIVITY IS OVER THE SC COUNTIES...WHERE HEATING WAS MAXIMIZED. DIURNAL INSTABILITY IS BEING AIDED BY LOW LEVEL CONVERGENCE JUST AHEAD OF COLD FRONT SAGGING IN FROM THE NORTH. ALTHOUGH WIDESPREAD SEVERE IS NOT EXPECTED...STEEP LOW LEVEL LAPSE RATES DO POINT TO STRONGEST STORMS HAVING THE CAPABILITY TO PRODUCE DAMAGING WINDS. OUTFLOW FROM THE STORMS...WHICH ARE SLOWLY MOVING SOUTH-SOUTHEAST...MAY ENHANCE ONGOING WEAKER CONVECTION ALONG THE FRONT...OR CAUSE ADDITIONAL STORMS TO DEVELOP. DO THINK CONVECTION ACROSS EASTERN AREA WILL INCREASE IN INTENSITY...BUT IT WILL TAKE LONGER AS THESE AREA HAVE NOT WARMED UP AS MUCH AS PORTIONS OF INLAND SC. DEVELOPING SEA BREEZE COULD ALSO BECOME A FOCUS FOR CONVECTION OVER THE NEXT FEW HOURS. COLD FRONT WILL CONTINUE MOVING SOUTH OVERNIGHT...THOUGH LOSS OF HEATING WILL LIKELY LEAD TO WANING PRECIP. LIFT ALONG THE WEAK FRONT DOES NOT APPEAR STRONG ENOUGH TO KEEP CONVECTION GOING ONCE THE SUN GOES DOWN. BOUNDARY LAYER MOISTURE AND LINGERING CLOUDS WILL KEEP LOWS ABOVE CLIMO...DESPITE COLD FRONT MOVING ACROSS MUCH OF THE AREA BY THE END OF THE PERIOD. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... AS OF 3 AM SATURDAY...DEEP MOISTURE WILL BECOME SUPPRESSED TO THE SOUTH ON SUNDAY AS BOTH SHORTWAVE IMPULSE AND SURFACE COLD FRONT MOVE OFF SC COAST NEAR CHS. THE WRF IS OVERLY BULLISH WITH THE LOW LEVEL DRYING WHEREAS THE GFS IS MORE CONSISTENT WITH OLDER RUNS AS WELL AS CONTINUITY. THE DIFFERENCE HAS BEEN PARTIALLY BLENDED WITH REGARDS TO RAIN CHANCES AND SURFACE DEWPOINT. AFTERNOON TEMPERATURES WILL BE CLOSE TO SEASONABLE NORMS. THE DEEP MOISTURE WILL BE EVEN FURTHER SUPPRESSED TO THE SOUTH ON MONDAY WHILE MID LEVEL HEIGHTS RISE SLIGHTLY DUE TO THE EXITED SHORTWAVE ENERGY. MONDAY LOOKS LIKE JUST ABOUT A RAIN-FREE DAY WITH VERY SIMILAR TEMPERATURES TO SUNDAY AFTERNOON. WEAK SYNOPTIC FLOW SHOULD MAKE MONDAY A BETTER SEA BREEZE DAY WITH JUST A SLIGHT COOLING AND ADDED HUMIDITY ALONG THE IMMEDIATE COAST. && .LONG TERM /TUESDAY THROUGH FRIDAY/... AS OF 3 AM SATURDAY...TUESDAY AND WEDNESDAY BRING A SYNOPTIC PATTERN MORE TYPICAL OF JULY WITH A LARGE UPPER RIDGE IN PLACE. THE NORMAL BERMUDA HIGH WILL BE DISPLACED TO THE EAST HOWEVER AND THIS WILL PREVENT MUCH MOISTURE RECOVERY FROM THE SUNDAY DRYING. TEMPERATURES WILL BE ABOVE NORMAL BUT RAIN CHANCES DON'T LOOK TOO GOOD. THE RIDGE ALOFT WILL ALREADY BE RETREATING WESTWARD BY WEDNESDAY. A COLD FRONT MAY SLOWLY TRAVERSE THE CAROLINAS NORTH TO SOUTH THURSDAY AND FRIDAY. THIS WILL CURB THE HEAT AND SLIGHTLY INCREASE RAIN CHANCES. AGAIN THOUGH WITH THE ABSENCE OF MUCH MOISTURE FLUX AHEAD OF THE BOUNDARY EVEN THIS INCREASE IN POPS MAY ONLY WARRANT SLIGHT CHANCE. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... AS OF 17Z...CONVECTION TAKING ITS SWEET TIME TO FORM...PROBABLY DELAYED DUE TO THE MVFR CEILINGS THIS MORNING. LOW LFC'S SHOULD HELP TO FIRE CONVECTION ANY TIME NOW...MAINLY ALONG THE FRONT WHICH IS OVER THE NORTHERN PORTION OF THE CWA. THE CONVECTION WILL DRIFT TO THE SOUTH ALONG WITH THE FRONT. BY 22Z...EXPECT THE CONVECTION TO BE CONFINED TO THE SOUTHERN THIRD OF THE REGION. BRIEF HEAVY RAIN COULD BRING VISIBILITIES AS LOW AS A MILE...HOWEVER THIS WILL ONLY LAST A FEW MINUTES AND WILL BE ISOLATED. OVERNIGHT...CONVECTION WILL COME TO AN END...OR AT LEAST BE JUST SOUTH OF THE CWA. DID NOT PUT MUCH FOG/STRATUS AT THIS TIME...BUT MAY HAVE TO ADD SOME...DEPENDING ON WHO GETS HEAVY RAIN. THERE WILL ALSO BE A VERY LIGHT NORTH NORTHEAST FLOW AFTER FRONTAL PASSAGE. THIS COULD ADD TO THE CHANCE FOR FOG/STRATUS. SUNDAY...ANY FOG OR STRATUS WILL MIX OUT BY MID MORNING...WITH NORTHEAST FLOW BEHIND THE FRONT. ISOLATED CONVECTION IS POSSIBLE BY AFTERNOON OVER THE EXTREME SOUTHWESTERN PORTION OF THE CWA. EXTENDED OUTLOOK...VFR MONDAY AND TUESDAY WITH LOW CONFIDENCE FOR BRIEF MORNING FOG. SCATTERED SHOWERS POSSIBLE TUESDAY NIGHT AND WEDNESDAY WITH ANOTHER WEAK FRONT. && .MARINE... NEAR TERM/THROUGH TONIGHT/... AS OF 2 PM SATURDAY...SOUTHWEST WINDS CONTINUE A SLOW WEAKENING TREND AS SURFACE GRADIENT CONTINUES TO RELAX. APPROACH AND PASSAGE OF WEAKEN COLD FRONT FROM THE NORTH WILL EVENTUALLY CAUSE WINDS TO SHIFT FROM SOUTHWEST TO NORTH-NORTHEAST THIS EVENING AND OVERNIGHT. CURRENTLY WINDS ARE BETWEEN 10 AND 15 KT BUT WILL DROP UNDER 10 KT AND BECOME HIGHLY VARIABLE IN THE VICINITY OF THE FRONT. LACK OF SIGNIFICANT GRADIENT POST FRONT WILL KEEP NORTHERLY FLOW 10 KT OR LESS. SEAS 3 TO 5 FT THIS AFTERNOON...MAINLY A 3 TO 5 FT SOUTHERLY 8 SEC SWELL...WILL DROPPING TO 2 TO 4 FT BY THE END OF THE PERIOD. SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... AS OF 3 AM SATURDAY...A FRONT WILL BACK THE WINDS TO A MORE NORTHERLY DIRECTION ON SUNDAY ESPECIALLY OVER NORTHERN ZONES. AS THIS BOUNDARY WEAKENS AND SINKS FURTHER SOUTH ALONG THE SOUTH CAROLINA COAST THE FLOW WILL HAVE A CHANCE TO VEER SLIGHTLY TO E OR EVEN SE. THE EXACT FATE OF THE BOUNDARY AND THUS RESULTING WIND DIRECTION IS A LITTLE UNCERTAIN. HOWEVER IT DOES APPEAR THAT WIND SPEED WILL REMAIN QUITE LIGHT THROUGH MOST OF THE PERIOD...10 KT OR SO. THE EXCEPTION WILL BE EARLY ON WHERE NE TO E WINDS MAY AVERAGE 10 TO 15KT ON SUNDAY. NO LOW LEVEL JETTING APPEARS IN THE OFFERING AND VERTICAL WIND ALIGNMENT WILL BE POOR SO GUSTINESS SHOULD BE MINIMIZED. LONG TERM /TUESDAY THROUGH WEDNESDAY/... AS OF 3 AM SATURDAY...HIGH PRESSURE NORMALLY IN THE WEST ATLANTIC ON TUESDAY WILL BE FURTHER EAST INTO THE CENTRAL ATLANTIC. LOCALLY THIS WILL WILL YIELD A TYPICAL SOUTHWESTERLY WIND DIRECTION. THE DISPLACEMENT OF THE HIGH WILL LEAD TO A LESSER GRADIENT AND LOWER WIND SPEED THAN NORMAL BUT THIS WILL BE LARGELY COMPENSATED FOR BY A WELL DEVELOPED PIEDMONT TROUGH. A COLD FRONT MANAGES TO ENTER THE WATERS LATER WEDNESDAY VEERING THE WINDS AROUND TO A MORE ONSHORE DIRECTION. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE.
