NWS Raleigh, NC wrote its last area forecast discussion before the first event at Aug 22, 9:15 AM EST, 1 hour 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 1015 AM EDT SAT AUG 22 2009 .SYNOPSIS... A VERY MOIST AIR MASS COUPLED WITH THE APPROACH OF AN UNSEASONABLY STRONG UPPER LEVEL TROUGH WILL RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE AREA TODAY AND TONIGHT. DRIER AIR ALOFT WILL OVERSPREAD THE REGION SUNDAY...LIMITING THE DEVELOPMENT OF SHOWERS AND STORMS. WEAK HIGH PRESSURE WILL BUILD INTO THE AREA FROM THE NORTHWEST MONDAY INTO TUESDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... AS OF 1015 AM... BROAD WEAK SURFACE TROUGH STRETCHING NORTHEAST TO SOUTHWEST THROUGH CENTRAL NORTH CAROLINA AT THIS TIME. WINDS EXPECTED TO SHIFT TO NORTH NORTHEAST TO NORTHEAST IN WEST PARTS TOWARD 6 PM WITH TROUGH LOCATED ROUGHLY CHARLOTTE TO RALEIGH. BEST RAIN CHANCES WILL LIKELY TRANSLATE EAST WITH TIME ALONG WITH THE SURFACE TROUGH AND WIND SHIFT. ALL INSTABILITY PARAMETERS CONTINUE HIGH WITH 2000 PLUS CAPE... TWO INCH PRECIPITABLE WATERS AND DEEP 20 TO 25 KNOT LAYER OF SOUTHWEST WINDS. NO SEVERE WEATHER FRIDAY IN THE AREA. WITH A BIT MORE VIGOROUS LOW LEVEL FORCING TODAY A FEW STORMS SHOULD GO MARGINALLY SEVERE WITH GUSTY DOWNBURST WINDS THE THREAT. FLOOD THREAT WILL BE LIMITED IF STORMS CONTINUE TO MOVE WITH DECENT SPEED AND NOT BACKBUILD. HOWEVER WITH BRIEF RAINFALL RATES IN EXCESS OF TWO INCHES PER HOUR... SOME URBAN AND SMALL STREAM AREA MAY SEE SOME PROBLEMS. CERTAINLY A SITUATION TO BE MONITORED. AFTERNOON TEMPERATURES WARMED SLIGHTLY OVER PREVIOUS FORECAST BUT AS ALWAYS CLOUDS AND PRECIPITATION MIGHT INTERFERE. && .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/... AS OF 305 AM SATURDAY... TONIGHT...PRESENCE OF 850 TO 700 MILLIBAR TROUGH IN VICINITY SHOULD MAINTAIN SCATTERED CONVECTION OVER THE EAST HALF THIS EVENING THEN DIMINISH TO ISOLATED COVERAGE AFTER MIDNIGHT AS THE LOWER LEVELS STABILIZE DUE TO NOCTURNAL COOLING. SURFACE BOUNDARY MARKING THE LEADING EDGE OF SLIGHTLY DRIER AIR FORECAST TO CROSS THE WESTERN PIEDMONT OVERNIGHT AND LIE IN VICINITY OF HIGHWAY ONE OR INTERSTATE 95 BY 12Z SUNDAY. DUE TO SLOWER FRONTAL MOVEMENT...RAISED MINIMUM TEMPERATURES TONIGHT 2 TO 3 DEGREES MOST LOCALES FRO PREVIOUS FORECAST. NOT OVERLY IMPRESSED WITH THREAT FOR SEVERE STORMS TODAY THOUGH CANNOT TOTALLY RULE OUT. MAIN SEVERE WEATHER HAZARD WILL BE LOCALLY EXCESSIVE RAINFALL AS UNIDIRECTIONAL FLOW THROUGH THE COLUMN SUGGEST POTENTIAL FOR SHOWERS OR THUNDERSTORMS TO MOVE REPEATEDLY OVER THE SAME LOCATION, WITH PRECIPITABLE WATER VALUES AROUND 2 TO 2.25 INCHES...SOME LOCATIONS MAY RECEIVE 1 TO 2 INCHES OF RAIN IN LESS THAN HOUR. IF THIS TYPE OF RAINFALL MATERIALIZES OVER AN URBANIZED AREA...STREET AND LOW LYING FLOODING WILL OCCUR. MODEL GUIDANCE DIVERGES SUNDAY. NAM-WRF DEPICTS UPPER LOW FORMING IN BASE OF LONG WAVE TROUGH OVER THE SOUTHERN APPALACHIANS BY LATE SUNDAY. NAM-WRF ALSO MAINTAINS MOISTURE THROUGH A RELATIVELY DEEP LAYER OF ATMOSPHERE. MEANWHILE GFS AND GEM SLOWLY LIFT LONG WAVE TROUGH TO THE NORTH NORTHEAST (GFS MORE SO THAN GEM) WITH PLENTY OF DRY AIR IN THE MID/UPPER LEVELS. 00Z ECMWF DEPICTS A SCENARIO SOMEWHAT SIMILAR TO THE NAM-WRF ALTHOUGH WEAKER...DRIER AND A LITTLE QUICKER LIFTING UPPER TROUGH NORTHWARD. IF NAM-WRF SCENARIO VERIFIES...THEN WOULD SEE INCREASING MID/UPPER LEVEL DIVERGENCE OVER REGION SUNDAY AFTERNOON...LEADING TO POTENTIAL FOR SCATTERED SEVERE STORMS. GFS- GEM SOLUTION SUPPORTS ISOLATED STORMS AS FAR WEST AS THE WESTERN PIEDMONT WITH SCATTERED STORMS POSSIBLE ALONG THE SURFACE BOUNDARY IN THE COASTAL PLAIN. NAM-WRF SOLUTION A BIT OF AN OUTLIER FOR NOW BUT CANNOT BE RULED OUT. PLAN TO INCREASE POPS TO SLIGHT CHANCE IN THE WEST TO SMALL CHANCE EAST SUNDAY. VAST MAJORITY OF CONVECTION OCCURRING AT 23Z SUNDAY WILL DISSIPATE WITH LOSS OF HEATING. MIXING OF DRIER AIR ALOFT WILL LOWER DEWPOINTS INTO THE LOWER 60S IN THE WEST AND INTO THE MID/UPPER 60S IN THE FAR EAST. ANY STORMS THAT FORM AND ABLE TO ATTAIN SUFFICIENT HEIGHT (AT OR ABOVE 25000 FEET) WILL HAVE POTENTIAL TO PRODUCE STRONG GUSTY WINDS DUE TO PRESENCE OF DRIER AIR IN THE MID/UPPER LEVELS.THICKNESS SUPPORT MAXIMUM TEMPERATURES IN THE 85 TO 90 DEGREE RANGE. MONDAY INTO TUESDAY...SURFACE HIGH BUILDING SE INTO REGION FROM THE GREAT LAKES WILL SLOWLY SHIFT SURFACE BOUNDARY OVER THE COASTAL PLAIN SSOUTHEAST. THIS FEATURE INTERACTING WITH A MARGINALLY MOIST AND UNSTABLE AIR MASS MAY TRIGGER ISOLATED CONVECTION MONDAY AFTERNOON IN VICINITY OF CLINTON...FAYETTEVILLE...LAURINBURG AND GOLDSBORO. BY TUESDAY...APPEARS THAT LOW LEVEL ANTI-CYCLONIC FLOW WILL DOMINATE...LIMITING CONVECTIVE DEVELOPMENT. LOW LEVEL NORTH FLOW WILL ADVECT DRIER AIR INTO THE REGION. DEWPOINTS MAY LOWER INTO THE UPPER 50S ACROSS THE PIEDMONT MONDAY AFTERNOON AND AGAIN TUESDAY AFTERNOON. THICKNESSES SUPPORT TEMPERATURES CLOSE TO SEASONAL NORMS IN THE 85 TO 90 DEGREE RANGE. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... AS OF 420 AM SATURDAY... WEDNESDAY THROUGH WEDNESDAY NIGHT: MEDIUM RANGE MODELS CONTINUE TO INDICATE A WEAK MID AND UPPER SHEAR AXIS REMAINING OVER THE PORTIONS OF THE GULF COAST STATES EXTENDING NORTHEASTWARD INTO THE MID-ATLANTIC REGION. HOWEVER... WITH SURFACE HIGH PRESSURE EXPECTED TO STILL BE IN PLACE OVER THE AREA AND A FAIRLY IMPRESSIVE MID LEVEL CAP STILL IN PLACE... EXPECTED CONDITIONS TO REMAIN DRY. THE ONE EXCEPTION TO THIS MAY BE IN THE SOUTHEAST... WHERE THE BEST LOW LEVEL MOISTURE IS EXPECTED TO RESIDE... ALONG WITH THE HELP FROM THE SEA BREEZE. THUS.. WILL KEEP SLIGHT CHANCE POPS IN THE SOUTHEAST FOR WEDNESDAY AFTERNOON. OTHERWISE DRY CONDITIONS ARE EXPECTED FOR WEDNESDAY AND WEDNESDAY NIGHT. HIGHS ON WEDNESDAY LOOK TO BE IN THE UPPER 80S TO LOWER 90S... AS LOW LEVEL THICKNESS VALUES ARE FORECAST TO BE IN THE 1415 TO 1420 METER RANGE. LOWS WEDNESDAY NIGHT/THURSDAY MORNING ARE EXPECTED TO BE IN THE UPPER 60S TO LOWER 70S. THURSDAY THROUGH FRIDAY: MEDIUM RANGE MODELS BEGIN TO DIVERGE A BIT FOR THURSDAY INTO FRIDAY. BOTH THE GFS AND THE EC DEPICT AN INVERTED SURFACE TROUGH OFFSHORE EXTENDING NORTHWARD FROM A WEAK AREA OF LOW PRESSURE LOCATED OFF THE SOUTHEAST UNITED STATESS COAST. THIS INVERTED SURFACE TROUGH HELPS TO PINCH OFF THE SURFACE RIDGE AXIS FROM THE HIGH PRESSURE CENTER LOCATED WELL OFFSHORE IN THE WESTERN ATLANTIC. THIS WILL CREATE A VERY WEAK AND ILL DEFINED SURFACE PATTERN ACROSS OUR AREA ON THURSDAY... POSSIBLY CONTINUING INTO FRIDAY. MEANWHILE... EXPECT A NORTHERN STREAM TROUGH ALOFT TO TRACK EASTWARD ACROSS EASTERN CANADA AND INTO THE NORTHEAST ON WEDNESDAY INTO THURSDAY... SENDING A WEAK TRAILING COLD FRONT SOUTHWARD... AS HIGH PRESSURE AT THE SURFACE BUILDS SOUTH OUT OF CENTRAL CANADA AND INTO THE GREAT LAKES REGION AND INTO THE NORTHEAST BY FRIDAY. THE BIG QUESTION FOR US... IS HOW FAR SOUTH WILL THIS SURFACE COLD FRONT MAKE IT. THE EC TRIES TO BRING THE FRONT INTO THE REGION BY FRIDAY MORNING... WHICH WOULD SERVE AS A FOCUS FOR PRECIPITATION... AND ALLOW COOLER TEMPERATURES TO FILTER INTO THE AREA. WHILE THE GFS HOLD THE FRONT TO THE NORTH OF THE REGION... AS AS THE REMAINING WEAK SHEAR AXIS OVER THE WESTERN GULF COAST STATES STRENGTHENS A BIT AS ADDITIONAL ENERGY FROM THE WEST COMBINES WITH IT. THIS WOULD PROVIDE OUR AREA WITH SOUTHWEST FLOW ALOFT... AND HOT AND HUMID CONDITIONS... WITH AN INCREASING CHANCE OF PRECIPITATION BY FRIDAY. FOR NOW WILL TREND A BIT MORE TOWARDS THE GFS... AS THE SUBTROPICAL RIDGE OVER THE SOUTHEAST UNITED STATES SHOULD HELP FIGHT THE BACK DOOR COLD FRONT OFF. THUS... WILL KEEP A SLIGHT CHANCE FOR AFTERNOON SHOWERS AND THUNDERSTORMS EACH DAY... WITH HIGH ON THURSDAY GENERALLY IN THE LOWER 90S. WILL KEEP HIGH A TOUGH COOLER ON FRIDAY DO TO THE UNCERTAINTY AND THE INCREASE IN MOISTURE AND SUBSEQUENT CLOUD COVER. HIGH FRIDAY ARE EXPECTED TO BE IN THE MID TO UPPER 80S. LOWS FRIDAY MORNING ARE EXPECTED TO BE IN THE UPPER 60S TO LOWER 70S. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... AS OF 755 AM SATURDAY... DEEP UPPER LEVEL TROUGH AND ATTENDANT COLD FRONT TO THE WEST OF THE AREA... WILL CONTINUE TO PROVIDE CENTRAL NORTH CAROLINA THIS MORNING WITH A VERY MOIST ATMOSPHERE. DESPITE DEWPOINTS THIS MORNING IN THE LOWER TO MID 70S... AND A WEAK TROUGH OF LOW PRESSURE ACROSS THE WESTERN PIEDMONT... CONVECTIVE ACTIVITY CONTINUES TO BE SUPPRESSED ACROSS THE AREA. MVFR/IFR STRATUS AND OR FOG HAS DEVELOPED THIS MORNING AT KRWI AND KFAY. AT KRDU/KGSO/KINT WE MAY HAVE A BRIEF PERIOD OF REDUCED VISIBILITIES THROUGH 13Z. THUS... HAVE ONLY INCLUDED MVFR CONDITIONS IN A TEMPO GROUP AT THESE SITES. EXPECT CONDITIONS AT ALL TAF SITES... EXCEPT KRWI... TO BECOME VFR BY 13Z. AT KRWI... THE STRATUS MAY HANG ON A BIT LONGER... PERHAPS AS LONG AS 15Z OR SO. SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED BY MID TO LATE MORNING IN THE WEST... WITH WIDESPREAD SHOWERS AND STORMS EXPECTED FROM KRDU EASTWARD DURING THE AFTERNOON. THUS... HAVE INCLUDED CB AT ALL TAF SITES FOR AFTERNOON... AND VCTS FROM KRDU EASTWARD... WHERE COVERAGE LOOKS TO BE BETTER. DRIER AIR ALOFT WILL FILTER INTO THE REGION FROM THE WEST LATE THIS AFTERNOON INTO THE EVENING... HELPING TO DECREASE CHANCES FOR PRECIPITATION FROM WEST TO EAST WITH TIME. THUS... EXPECTED DRY CONDITIONS AT KGSO AND KINT AFTER 00Z... WITH CONTINUED CHANCES FOR SHOWERS AND POSSIBLY THUNDERSTORMS AT KRDU/KFAY/KRWI THROUGH GENERALLY 04Z... POSSIBLY A BIT LONGER... AS THE FRONT SHOULD BE STALLED SOMEWHERE ACROSS THE EASTERN PORTION OF CENTRAL NORTH CAROLINA THEN. WITH DRIER AIR FILTER INTO THE AREA ALOFT OVERNIGHT... WE WILL HAVE TO WATCH OUT FOR THE POTENTIAL FOR SUB VFR VISIBILITIES... ESPECIALLY IF SKIES ARE ABLE TO CLEAR OFF A BIT AND APPRECIABLE RAIN IS RECEIVED FROM SHOWERS AND THUNDERSTORMS THIS AFTERNOON AT THE TERMINALS. THE FRONT IS EXPECTED STALL ACROSS THE REGION ON SUNDAY PROVIDING THE EASTERN PORTIONS OF THE AREA WITH ISOLATED TO POSSIBLY SCATTERED SHOWERS AND THUNDERSTORMS FROM KRDU EASTWARD. THE FRONT SHOULD PUSH EAST OF THE AREA BY SUNDAY NIGHT. VFR SKIES/VISIBILITIES SHOULD RETURN TO ALL AREAS MONDAY AFTERNOON THROUGH WEDNESDAY. && .RAH WATCHES/WARNINGS/ADVISORIES...
