A strong cold front moved through the region, with scattered sub-severe convection developing along and ahead of the front. However, strong pressure rises (as much as 6mb/3hr) occurred behind the front, which resulted in non-thunderstorm wind damage.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 342 PM EDT THU SEP 15 2011 .SYNOPSIS... A STRONG COLD FRONT WILL PUSH SOUTHEAST THROUGH THE REGION LATE THIS AFTERNOON AND EVENING...AND BREEZY NORTHERLY WINDS IN THE WAKE OF THE FRONT WILL USHER IN A MUCH COOLER AIR MASS OVERNIGHT. TEMPERATURES WILL BE DRAMATICALLY COOLER IN THE WAKE OF THE FRONT ON FRIDAY AND SATURDAY...WITH CLOUDY SKIES AND A CHANCE OF RAIN OR DRIZZLE PERSISTING THROUGH SATURDAY NIGHT. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... AS OF 245 PM THURSDAY... OVERVIEW: AN UPPER LEVEL TROUGH CURRENTLY OVER THE GREAT LAKES WILL PROGRESS EAST INTO NEW ENGLAND BY 00Z THIS EVENING...AND INTO THE CANADIAN MARITIMES BY 12Z FRIDAY. STRONG HIGH PRESSURE (1032 MILLIBAR) CURRENTLY CENTERED OVER MINNESOTA (WHERE MORNING LOWS WERE IN THE 20S) WILL ADVANCE TOWARD LAKE MICHIGAN BY 00Z THIS EVENING...AND INTO THE OHIO VALLEY BY 12Z FRIDAY (IN ASSOCIATION WITH STRONG SUBSIDENCE IN THE WAKE OF THE AFOREMENTIONED UPPER LEVEL TROUGH). DRIVEN BY THE ADVANCING SURFACE HIGH/PRESSURE RISES...A STRONG COLD FRONT (CURRENTLY APPROACHING THE SOUTHERN APPALACHIANS) WILL MAKE QUICK PROGRESS THROUGH CENTRAL NORTH CAROLINA LATER THIS AFTERNOON AND EVENING...AND IS EXPECTED TO PUSH SOUTH OF THE AREA BY ABOUT 03Z TONIGHT. STRONG PRESSURE RISES (AS MUCH AS 6 MILLIBAR IN 3 HOURS) IN THE WAKE OF THE FRONT WILL ALLOW FOR BREEZY CONDITIONS TONIGHT AND FRIDAY MORNING...WITH SUSTAINED NORTHEAST WINDS OF 15 TO 20 MPH AND GUSTS UP TO 30 MPH. TEMPERATURES: 1000 TO 850 MB THICKNESSES TODAY ARE VERY SIMILAR TO YESTERDAY (1410 TO 1420 METERS)...WHEN HIGHS REACHED INTO THE UPPER 80S TO LOWER 90S. THE PRIMARY UNCERTAINTY WITH HIGHS TODAY WILL REVOLVE AROUND THE AFOREMENTIONED COLD FRONTAL PASSAGE AND INCREASING CLOUD COVER FROM THE WEST. BASED ON THE LATEST AVAILABLE MODEL GUIDANCE AND OBSERVATIONAL DATA...EXPECT THE FRONTAL PASSAGE TO OCCUR BY 21Z (PEAK HEATING) IN THE FAR NORTH AND NORTHWEST PIEDMONT...AND BY 00Z ELSEWHERE EXCEPT PERHAPS THE FAR SOUTHEAST COASTAL PLAIN. AS A RESULT...THE MOST UNCERTAINTY WITH HIGHS TODAY WILL BE NORTH OF THE HIGHWAY 64 CORRIDOR...AND MORE SPECIFICALLY IN THE NORTH AND NORTHWEST PIEDMONT. GIVEN THAT THE TIMING OF THE FRONTAL PASSAGE SHOULD ALLOW FOR FULL DIURNAL HEATING IN MOST LOCATIONS...AT THIS TIME WILL INDICATE HIGHS SIMILAR TO YESTERDAY...IN THE UPPER 80S TO LOWER 90S...EXCEPT MID 80S IN THE FAR NORTH/NORTHWEST PIEDMONT WHERE COLD ADVECTION AND INCREASING CLOUD COVER HAS THE BEST CHANCE TO PREVENT FULL DIURNAL HEATING. OVERNIGHT... LOWS WILL BE DRIVEN BY COLD ADVECTION IN THE WAKE OF THE FRONT. BASED ON THE UPSTREAM AIR MASS AND LATEST MOS GUIDANCE...EXPECT LOWS TO RANGE FROM THE LOW TO MID 50S NORTH/NORTHWEST TO THE UPPER 50S TO NEAR 60F IN THE FAR SOUTH AND SOUTHEAST. IF ANY LIGHT RAIN OR DRIZZLE DEVELOPS IN THE WAKE OF THE FRONT PRIOR TO SUNRISE...TEMPERATURES COULD WETBULB DOWN INTO THE UPPER 40S. PRECIPITATION CHANCES: WITH REGARD TO FORCING...STRONG LOW LEVEL CONVERGENCE WILL BE PRESENT LATER THIS AFTERNOON AND EVENING AS THE AFOREMENTIONED COLD FRONT PROGRESSES INTO THE AREA FROM THE NORTHWEST. ALOFT...FORCING WILL PRIMARILY BE LIMITED TO A WEAK UPPER LEVEL DISTURBANCE NOTED JUST UPSTREAM OF THE AREA IN WESTERLY FLOW ALOFT. THE BEST UPPER LEVEL SUPPORT WILL REMAIN WELL NORTH OF THE AREA TODAY...OVER NEW ENGLAND IN ADVANCE OF THE UPPER LEVEL TROUGH CURRENTLY PROGRESSING THROUGH THE GREAT LAKES. WITH REGARD TO INSTABILITY...FORECAST SOUNDINGS SHOW A DEEP/DRY SUB CLOUD LAYER (UP TO ABOUT 7 THOUSAND FEET AGL) TODAY...WITH SURFACE DEWPOINTS IN THE MID/UPPER 50S TO LOWER 60S. AS A RESULT... INSTABILITY SHOULD BE ON THE MARGINAL SIDE...NO MORE THAN 500 TO 1000 J/KG OF MLCAPE. THE 00Z WRF AND NMM INDICATE SCATTERED CONVECTION DEVELOPING ALONG AND AHEAD OF THE FRONT IN THE NORTH/NORTHWEST PIEDMONT BY 19 TO 21Z THIS AFTERNOON...PROGRESSING SOUTHEAST THROUGH THE AREA BY ABOUT 03Z TONIGHT. WITH THE ABOVE IN MIND...WILL KEEP PRECIPITATION CHANCES SIMILAR TO THE PREVIOUS FORECAST...ALTHOUGH SLIGHTLY HIGHER (40 PERCENT) IN EAST/SOUTHEAST PORTIONS OF THE AREA IN DEFERENCE TO THE 00Z WRF AND NMM...WHERE THE FRONTAL PASSAGE TIMING WILL BETTER COINCIDE WITH PEAK HEATING. A NARROW BAND OF LIGHT RAIN/SPRINKLES WILL BE POSSIBLE AFTER THE FRONTAL PASSAGE ON THE COOL SIDE OF THE FRONT. OVERNIGHT...A WARM/MOIST SOUTHWEST FLOW ALOFT WILL OVERRUN A COLDER/DRIER NEAR SURFACE AIR MASS DEPOSITED IN THE WAKE OF THE FRONT... RESULTING IN OVERCAST SKIES. THE LATEST MODEL GUIDANCE MAINTAINS A DRY SUB CLOUD LAYER IN THE LOWEST 3 TO 4 THOUSAND FEET OVERNIGHT...INDICATING THAT FRONTOGENESIS OR ISENTROPIC LIFT ASSOCIATED WITH THE 850 MILLIBAR FRONT EXPECTED TO STALL OVER OR JUST SOUTH OF THE AREA WILL BE INSUFFICIENT TO RESULT IN MEASURABLE PRECIPITATION. AT THIS TIME WILL MAINTAIN A SLIGHT CHANCE OF LIGHT RAIN OR DRIZZLE ACROSS THE ENTIRE AREA AFTER MIDNIGHT. SEVERE THREAT: INSTABILITY WILL BE ON THE MARGINAL SIDE...AND 0 TO 6 KM BULK SHEAR VALUES ARE EXPECTED TO BE ABOUT 25 KNOTS OR LESS OVER CENTRAL NORTH CAROLINA THROUGH 00Z...WITH THE BEST DEEP LAYER SHEAR TO THE NORTH IN VIRGINIA. GIVEN MARGINAL INSTABILITY AND DEEP LAYER SHEAR ABOUT 25 KNOTS OR LESS DURING THE TIME FRAME THAT CONVECTION WILL BE POSSIBLE ALONG/AHEAD OF THE FRONT...FEEL THAT CONVECTIVE ORGANIZATION WILL BE LIMITED TO MULTICELLULAR AT BEST. HOWEVER...GIVEN A WARM/DRY BOUNDARY LAYER WITH DCAPE VALUES 1000 PLUS J/KG DURING PEAK HEATING (PRIMARILY IN EASTERN PORTIONS OF THE AREA WHERE THERE WILL BE LESS CLOUD COVER AND MORE INSOLATION)...A LOW END/CONDITIONAL THREAT FOR DAMAGING WINDS WILL BE POSSIBLE IN ASSOCIATION WITH ANY DEEP CONVECTION THAT DEVELOPS...WITH THE BEST CHANCE IN THE NORTHEAST COASTAL PLAIN WHERE THE RELATIVE BEST COMBINATION OF FORCING/INSTABILITY/SHEAR/DCAPE IS FORECAST. -VINCENT && .SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/... AS OF 245 PM THURSDAY... FRIDAY: COLD/DRY SURFACE HIGH PRESSURE WILL BE IN PLACE ACROSS CENTRAL NORTH CAROLINA ON FRIDAY...WHILE A RELATIVELY WARM AND MOIST WEST-SOUTHWESTERLY MID LEVEL FLOW OVERRUNS THE COLD AIR IN THE LOWEST 4 TO 7 THOUSAND FEET. THIS WILL RESULT IN OVERCAST SKIES...AND THE BEGINNING OF AN EARLY SEASON COLD AIR DAMMING WEDGE. THE BIGGEST UNCERTAINTY WITH THE FORECAST ON FRIDAY WILL BE PRECIPITATION CHANCES AND TEMPERATURES. BOTH THE 12Z GFS AND NAM ARE INDICATING A TRACE TO A FEW HUNDREDTHS OF AN INCH OF PRECIPITATION POSSIBLE FRIDAY AFTERNOON...HOWEVER...FORECAST SOUNDINGS CONTINUE TO SHOW A DEEP/DRY SUB CLOUD LAYER IN THE LOWEST 4 TO 7 THOUSAND FEET THROUGHOUT THE DAY ON FRIDAY... SUGGESTING THAT TOP- DOWN SATURATION MAY TAKE A WHILE. GIVEN UNIDIRECTIONAL (WESTERLY) FLOW ALOFT AND NO SIGNIFICANT UPPER LEVEL SUPPORT...PRECIPITATION CHANCES WILL BE TIED PRIMARILY TO LOWER LEVEL FORCING...IN THE FORM OF WEAK FRONTOGENESIS AND ISENTROPIC LIFT NEAR THE 850 MILLIBAR FRONT EXPECTED TO STALL NEAR OR OVER CENTRAL NORTH CAROLINA. THE LATEST 12Z MODEL GUIDANCE INDICATES THAT LOW LEVEL LIFT SHOULD GENERALLY BE INSUFFICIENT TO RESULT IN MEASURABLE PRECIPITATION. AS A RESULT... WILL KEEP CHANCES FOR RAIN AT 20 TO 30 PERCENT AT BEST DURING THE DAY FRIDAY. GIVEN PERVASIVE CLOUD COVER AND A MUCH COOLER AIR MASS IN PLACE... EXPECT HIGHS ON FRIDAY TO TOP OUT IN THE UPPER 50S TO LOWER 60S. ONE CAVEAT TO THE HIGH TEMPERATURE FORECAST ON FRIDAY IS THAT IT ASSUMES NO PRECIPITATION. GIVEN THE VERY DRY AIR MASS IN PLACE...IF LOW LEVEL LIFT IS INDEED STRONG ENOUGH TO RESULT IN MEASURABLE PRECIPITATION...EVAPORATIVE COOLING COULD RESULT IN AFTERNOON TEMPERATURES FALLING AS LOW AS THE UPPER 40S TO LOW TO MID 50S. -VINCENT && .LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/... AS OF 345 PM... FRIDAY NIGHT THROUGH SATURDAY NIGHT CHALLENGING FORECAST AS COLD AIR DAMMING EVENT ALMOST ALWAYS ARE. PLACEMENT TIMING AND DURATION OF PRECIPITATION WILL BE KEY TO FORECASTING TEMPERATURES. GIVEN THE STABLE COLD NEAR SURFACE AIR MASS... ONLY RAIN OR DRIZZLE FORECAST DURING THIS PERIOD. SURFACE RIDGING CENTERED OVER THE FOOTHILLS AND NORTHWEST PIEDMONT IS FORECAST FOR FRIDAY EVENING. MODELS IN GENERAL AGREEMENT IN INCREASING SOUTH OVERRUNNING FLOW OVER THE COLD AIR DOME LATE FRIDAY INTO FRIDAY NIGHT WITH THE ECMWF AND NAM DRAPING AN EAST WEST 850 MILLIBAR BOUNDARY IN THE VICINITY OF HIGHWAY 64. THIS UPPER BOUNDARY PUSHES NORTH TO THE VIRGINIA BORDER BY SUNRISE. IF THIS SCENARIO IS EVEN REMOTELY TRUE...RAIN SEEM UNAVOIDABLE... WITH THE BEST CHANCES NEAR AND AFTER MIDNIGHT... WHEN DIRECTIONAL AND SPEED CONVERGENCE ABOVE THE COLD DOME IS BEST. 850 MILLIBAR OVERRUNNING FLOW INCREASES FURTHER SATURDAY AFTER SUNRISE WITH EAST TO SOUTHEAST WINDS RISING TO THIRTY TO THIRTY-FIVE KNOTS. THE SLOPE OF THE COLD DOME AND MAXIMUM CONVERGENCE IS EXPECTED TO FAVOR OUR NORTHEAST PARTS. THE CURRENT THREE QUARTER INCH RAINFALL AMOUNTS IN THAT AREA FOR SATURDAY POTENTIALLY UNDERDONE. 850 MILLIBAR WINDS DEVELOP A NORTH COMPONENT TO THE FLOW SATURDAY NIGHT AND WEAKEN... RESULTING IN SUBSIDING LIFT. ONLY AREAS NEAR AND EAST OF HIGHWAY ONE EXPECTED TO RECEIVE MORE THAN A FEW HUNDREDTHS OF RAIN OVERNIGHT... MAINLY BEFORE MIDNIGHT. ALPHANUMERIC GUIDANCE FOR OVERNIGHT LOWS DIFFICULT TO BEAT WITH GUIDANCE RELATIVELY UNIFORM. HIGH TEMPERATURES SATURDAY ARE LOCKED TO THE PRECIPITATION FORECAST. IF THE RAINFALL FORECAST VERIFIES... A FOUR DEGREE DIURNAL RISE IN THE NORTHEAST REASONABLE... AND THE SEVEN TO TEN DEGREE RISE ELSEWHERE PERHAPS TOO GENEROUS. BASED ON THE CURRENT RAINFALL FORECAST... UPPER 50S FORECAST NORTH... WITH A FEW MID 50S... AND NEAR 60 TO 64 SOUTH. SUNDAY THROUGH THURSDAY WINDS ALOFT BECOME LIGHT AS WEAK MID LEVEL RIDGING BUILDS OVER TENNESSEE SUNDAY. LIGHT NORTHEAST SURFACE FLOW DURING THE DAY WITH LOW LEVEL MOISTURE CONTINUING TRAPPED BELOW 5000 FEET. WARM ADVECTION IN NORTH SURFACE FLOW FORECAST WITH BACKING WINDS ALOFT. THUS WILL FORECAST SOME SUNSHINE SUNDAY WITH AFTERNOON TEMPERATURES NEAR 70 NORTHWEST TO NEAR 75 SOUTHEAST. A SHOWER OR TWO NOT IMPOSSIBLE IN THE EAST DURING THE AFTERNOON... WHERE LOW LEVEL WINDS ARE BEST... BUT CHANCES NO MORE THAN ONE IN SEVEN. CLOUDS WILL BE SLOW TO LIFT MONDAY BUT SUNSHINE SHOULD MAKE AN APPEARANCE BEFORE NOON. MID LEVEL FLOW FROM THE EAST POTENTIALLY SPEED CONVERGENT AND ANY COASTAL SHOWER COULD ADVECT FURTHER INLAND TO AREAS EAST OF INTERSTATE 95 DURING THE AFTERNOON MONDAY THROUGH WEDNESDAY. HOWEVER RAIN CHANCES SLIGHT OR LESS IN THE EAST... TAPERING OFF TOWARD THE NORTHWEST. MID LEVEL FLOW MUCH MORE UNCERTAIN FOR THURSDAY... AND WILL OMIT ANY SIGNIFICANT RAIN CHANCE FROM GRIDDED FORECASTS FOR THURSDAY. TEMPERATURES IN GENERAL ON THE RISE MONDAY THROUGH THURSDAY. UPPER 70S TO NEAR 80 MONDAY RISING TO 80 TO 85 TUESDAY... THEN MID 80S WEDNESDAY AND THURSDAY. OVERNIGHT LOWS MID 50S TO LOWER 60S SUNDAY AND MONDAY NIGHTS... 60 TO 65 TUESDAY AND WEDNESDAY NIGHTS. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... AS OF 125 PM THURSDAY... 24-HR TAF PERIOD: VFR CONDITIONS ARE GENERALLY EXPECTED...WITH A POTENTIAL FOR MVFR CEILINGS BY THE END OF THE TAF PERIOD. A STRONG COLD FRONT WILL CROSS THE AREA FROM THE NORTHWEST LATER THIS AFTERNOON AND EVENING. BASED ON THE LATEST MODEL GUIDANCE...EXPECT THE FRONT TO FIRST CROSS KINT AND KGSO BY ABOUT 21Z...FOLLOWED BY KRDU AND KRWI BY ABOUT 23Z...AND FINALLY KFAY BY ABOUT 01Z. INITIALLY SOUTHWEST WINDS AT 5 TO 10 KNOTS WILL BECOME NORTHEAST AND STRENGTHEN DUE TO STRONG PRESSURE RISES IN THE WAKE OF THE COLD FRONT. EXPECT SUSTAINED NORTHEAST WINDS OF 15 TO 20 KNOTS WITH GUSTS AS HIGH AS 25 TO 30 KNOTS FOR A GOOD 3 TO 6 HOUR PERIOD IN THE WAKE OF THE FRONT. THEREAFTER...WINDS SHOULD DECREASE...BUT WILL LIKELY REMAIN SUSTAINED AT 10 TO 15 KNOTS WITH GUSTS UP TO 20 KNOTS. NORTHEAST WINDS WILL FURTHER SUBSIDE DURING THE DAY FRIDAY AS SURFACE HIGH PRESSURE BUILDS OVER THE MID ATLANTIC AND NORTH CAROLINA AND THE PRESSURE GRADIENT RELAXES. SOME UNCERTAINTY REMAINS WITH REGARD TO PRECIPITATION CHANCES AND CEILINGS ON FRIDAY...HOWEVER...BASED ON THE LATEST 12Z MODEL GUIDANCE...EXPECT DRY CONDITIONS TO PERSIST WITH CEILINGS AT 4000 FEET AGL OR HIGHER THROUGH THE END OF THE TAF PERIOD (18Z FRI). LOOKING AHEAD: BASED ON THE LATEST 12Z MODEL GUIDANCE...ADVERSE AVIATION CONDITIONS ARE EXPECTED THROUGH MOST OF THE WEEKEND. PRECIPITATION CHANCES ARE EXPECTED TO INCREASE FRIDAY NIGHT AND SATURDAY...REINFORCING THE COLD AIR DAMMING WEDGE IN PLACE ACROSS CENTRAL NORTH CAROLINA. AS A RESULT...EXPECT CONDITIONS TO DETERIORATE FROM VFR TO MVFR...AND EVENTUALLY TO IFR TO LIFR BY 12Z SAT MORNING. IFR TO LIFR CONDITIONS ARE EXPECTED TO PERSIST THROUGH SATURDAY NIGHT INTO PORTIONS OF SUNDAY. VFR CONDITIONS ARE EXPECTED TO RETURN BY MONDAY AFTERNOON. IT SHOULD BE NOTED THAT A FAIR AMOUNT OF UNCERTAINTY PERSISTS WITH REGARD TO PRECIPITATION CHANCES (AND THEREFORE CEILINGS AND VISIBILITIES) OVER THE WEEKEND. -VINCENT && .RAH WATCHES/WARNINGS/ADVISORIES...
