AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 210 PM EDT SUN SEP 2 2012 .SYNOPSIS... A WARM AND HUMID AIR MASS COUPLED WITH THE SLOW APPROACH OF AN UPPER LEVEL TROUGH WILL KEEP THE WEATHER UNSETTLED ACROSS CENTRAL NC THROUGH MID WEEK. && .NEAR TERM /THROUGH MONDAY NIGHT/... AS OF 145 PM SUNDAY... OVERVIEW: THE FOLLOWING SYNOPTIC FEATURES HAVE BEEN NOTED THIS AFTERNOON... -CIRCULATION ASSOC WITH ISAAC REMNANTS SLOWLY DRIFTING EAST ACROSS THE MIDWEST. -DIFFUSE SFC BOUNDARY DRAPED ACROSS NORTHCENTRAL AND NORTHEAST NC EXTENDING TO THE EAST AND WELL OFFSHORE -MIDLEVEL S/W RIDGE AXIS OVER THE CENTRAL CAROLINAS EXTENDING NORTH INTO VA...WITH A VORTICITY SHEAR AXIS JUST UPSTREAM AND CROSSING THE MOUNTAINS. FOR THE REST OF TODAY...SCATTERED SHOWERS/TSTMS HAVE DEVELOPED ACROSS OUR CENTRAL ZONES IN AN AREA OF LOW-LEVEL CONVERGENCE AND MODERATE INSTABILITY. EXPECT THIS ACTIVITY TO CONTINUE THIS AFTERNOON...AND ADDITIONAL ACTIVITY TO DEVELOP ACROSS THE THE WESTERN PIEDMONT WITH THE APPROACHING MID-LEVEL SHEAR AXIS. OUTFLOW BOUNDARIES FROM INITIAL ACTIVITY SHOULD TRIGGER ADDITIONAL CELLS WHICH WILL SLOWLY MOVE TOWARD THE EAST GIVEN A 240-270 DEG STORM MOTION <6 KTS AS SEEN IN FORECAST SOUNDINGS. LATEST MESOANALYSIS SHOWS THE BEST INSTABILITY ACROSS THE SOUTHERN HALF OF OUR FORECAST AREA. NOTED THAT BULK SHEAR REMAINS <20KT ACROSS OUR ENTIRE CWA. AS FOR DCAPE...WHILE BEST VALUES FOR WIND GUSTS ARE WELL TO OUR SOUTH...3 TO 6 HOUR RAP PROGS SUGGEST INCREASING DCAPE EXTENDING UP ACROSS THE COASTAL PLAIN AND THE SANDHILLS AREAS. FINALLY PWAT VALUES REMAIN RATHER HIGH (2+ INCHES) ACROSS MOST OF OUR CWA. SO IN SUMMARY...TSTMS SHOULD BE MORE PULSE IN NATURE...AND GIVEN ANTICIPATED SLOW MOVEMENT AND HIGH PWAT VALUES...HEAVY DOWNPOURS AND LOCAL POOR DRAINAGE FLOODING WILL BE THE PRIMARY CONCERN TODAY. A SECONDARY CONCERN WILL BE THE POTENTIAL FOR ISOLATED AND BRIEF DAMAGING WIND GUSTS...PARTICULARLY ACROSS THE S/SE HALF OF OUR CWA WHERE CAPE AND DCAPE ARE ENHANCED. TONIGHT...SHOWER/TSTM ACTIVITY SHOULD WIND DOWN BY 10 PM LEAVING THE OVERNIGHT PERIOD PARTLY TO MOSTLY CLOUDY. NO CHANGE IN AIRMASS FROM RECENT DAYS...SO EXPECT LOWS IN THE LOW-MID 70S. MONDAY AND MONDAY NIGHT...MID LEVEL CIRCULATION FROM ISAAC REMNANTS IS FORECAST TO SLOW FORWARD MOVEMENT AND SPLIT OVER THE OH/TN VALLEY AS IT ENCOUNTERS THE MID-LEVEL RIDGE ALONG THE MID ATLANTIC AND CAROLINA COAST. ONE PORTION OF THE AFOREMENTIONED CIRCULATION IS PROGGED TO MOVE TO THE NE AND ANOTHER TO THE S. SIMILAR TO TODAY... ANOTHER VORTICITY AXIS ROTATING AROUND THE LARGE-SCALE SYSTEM IS PROGGED TO CROSS THE MOUNTAINS DURING THE DAYTIME...AND SHOULD HELP SERVE AS A FOCUS FOR SHOWER/TSTM DEVELOPMENT PARTICULARLY ACROSS THE WESTERN HALF OF OUR CWA. SIMILAR TO TODAY...EXPECT A HIGH PWAT AND LOW SHEAR ENVIRONMENT TO SUPPORT PULSE TYPE ACTIVITY AND WITH STORM MOTION PROGGED AOB 7 KTS...ONCE AGAIN LOCALIZED POOR DRAINAGE FLOODING LIKELY TO BE THE PRIMARY CONCERN. AS FOR POPS...WILL CONTINUE TO CARRY STRONG-CHANCE POPS TAPERED SLIGHTLY HIGHER ACROSS OUR WESTERN HALF. LITTLE CHANGE IN AIRMASS SO WILL CONTINUE TO SEE ABOVE NORMAL TEMPS WITH HIGHS AROUND 90. GIVEN PROXIMITY OF ISAAC REMNANTS AND SUBSEQUENT MID LEVEL IMPULSES AROUND IT AND ENHANCED SOUTHERLY LOW-LEVEL FLOW... SHOWER/TSTM ACTIVITY MAY LINGER ON A BIT LONGER INTO THE EVENING HOURS...ESP ACROSS OUR WESTERN ZONES. LOWS MONDAY NIGHT ONCE AGAIN IN THE LOW-MID 70S. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... AS OF 210 PM SUNDAY... FOR TUESDAY/TUESDAY NIGHT: THE QUICKLY-DAMPENING MID LEVEL SHORTWAVE TROUGH -- THE REMAINS OF ISAAC -- WILL APPROACH WRN/CENTRAL NC FROM THE WEST ON TUESDAY... ALTHOUGH THE BULK OF THE DPVA WILL SLIDE TO OUR SW ACROSS GA WITH JUST A WEAK SHEAR AXIS SETTLING EASTWARD INTO THE NC MOUNTAINS BY TUESDAY NIGHT... WHILE ANOTHER WEAK PERTURBATION AND ATTENDANT SURFACE LOW TRACK JUST NORTH OF HIGHWAY 80 FROM LAKE ERIE TO NEW ENGLAND. DESPITE THE WEAKENING WAVE'S APPROACH FROM THE WEST... DYNAMIC FORCING FOR LIFT WILL BE QUITE LOW WITH WEAK MID LEVEL RIDGING OVER CENTRAL/ERN NC... WEAK MID LEVEL WINDS... AND LOW DEEP LAYER SHEAR (5-10 KTS AT BEST). MOISTURE WILL REMAIN DECENT IN THE WESTERN CWA WITH PW VALUES NEAR 2.0 INCHES... BUT WILL SEE LOWER VALUES (NEAR 1.5 INCHES--CLOSE TO NORMAL) IN THE EAST WHERE SOME DRIER MID LEVEL AIR WILL BE PULLED ONSHORE FROM THE ESE. ALSO... MODELS INDICATE SOMEWHAT POOR CONVECTIVE PARAMETERS WITH 1000-1500 J/KG MLCAPE CONFINED TO THE SOUTHWESTERN SECTIONS... AND THE MODELS ARE GENERATING VERY LITTLE QPF... WITH SREF PROBABILITIES OF ANY PRECIP HOLDING UNDER 30 PERCENT OVER ALL BUT THE FAR WEST. WILL HOLD ONTO CHANCE POPS IN THE FAR WEST TUESDAY... BUT WILL DROP TO JUST SLIGHT CHANCE OVER THE REST OF THE CWA. HIGHS 85-89 WITH THICKNESSES HOLDING ABOVE NORMAL. LOWS 69-73 WITH AREAS OF FOG DEVELOPING. FOR WEDNESDAY/WEDNESDAY NIGHT: THE WEAK MID LEVEL SHEAR AXIS CONTINUES TO DRIFT EASTWARD... MOVING INTO CENTRAL NC WEDNESDAY. ACCORDINGLY... THE HIGHER PW VALUES SPREAD EASTWARD AS WELL INTO THIS AREA... CLIMBING TO 2.0-2.2 INCHES IN A RIBBON THROUGH CENTRAL NC. INSTABILITY MAY BE A BIT BETTER AS WELL WITH MODELS SHOWING 1200-1800 J/KG OF MLCAPE AREAWIDE... HOWEVER DEEP LAYER SHEAR REMAINS POOR AT JUST 5-10 KTS. BUT THE HIGHER SREF PROBABILITIES OF MEASURABLE PRECIP KICK EASTWARD WEDNESDAY WITH 50-70 PERCENT CHANCES COVERING CENTRAL NC... AND WITH THE MINOR HEIGHT FALLS AND SLIGHT UPTICK IN DYNAMICALLY-INDUCED LIFT... WILL STAY WITH FORECAST OF SCATTERED STORMS AREAWIDE DEVELOPING IN THE AFTERNOON... CONTINUING THROUGH THE EVENING. THESE WILL LIKELY BE SLOW-MOVERS... WITH A HEIGHTENED THREAT OF STREET FLOODING. HIGHS AGAIN 85-89. LOWS 68-73 WITH ANOTHER ROUND OF FOG POSSIBLE LATE. -GIH && .LONG TERM /THURSDAY THROUGH SUNDAY/... AS OF 1140 AM SUNDAY... EXPECT WET WEATHER EARLY BUT WITH DRIER CONDITIONS HEADING INTO NEXT WEEKEND. THIS PERIOD BEGINS WITH FAST MID LEVEL FLOW AND A VERY BROAD TROUGH COVERING THE NORTHERN THIRD OF THE CONUS INTO CANADA (AROUND A STRONG VORTEX OVER FAR NRN ONTARIO)... WHILE AN E-W ELONGATED RIDGE COVERS THE FAR SOUTHWEST INTO NRN MEXICO... AND A WEAK LIKELY SUBTROPICAL LOW SITS JUST OFF THE NE COAST OF FL. A WEAK MID LEVEL SHEAR AXIS PERSISTS THROUGH THE CENTRAL CAROLINAS... ALONG A SURFACE LEE TROUGH... WELL AHEAD OF AN INCOMING SYNOPTIC COLD FRONT. FOR THURSDAY/THURSDAY NIGHT: ONE LARGE BUT LOW-AMPLITUDE SHORTWAVE TROUGH SWINGS THROUGH THE EASTERN GREAT LAKES/ST LAWRENCE VALLEY AND THE NORTHEAST STATES ON THURSDAY... AND THE ENSUING HEIGHT FALLS ALOFT COMBINED WITH DEEP MOISTURE IN PLACE AND PREFRONTAL INSTABILITY SHOULD INSTIGATE GOOD COVERAGE OF SHOWERS AND STORMS OVER CENTRAL NC... PARTICULARLY THURSDAY AFTERNOON AND EVENING... WITH GREATER COVERAGE ALONG/EAST OF HIGHWAY 1 GIVEN THE DRIER MID LEVEL AIR FILTERING INTO THE WEST. LOW LEVEL THICKNESSES REMAIN 5-10 METERS ABOVE NORMAL... ALTHOUGH THIS WARMTH WILL BE SOMEWHAT TEMPERED BY CONSIDERABLE MID AND HIGH CLOUDS. HIGHS MAINLY IN THE MID-UPPER 80S. THE LONGWAVE TROUGH BEGINS TO DIG PROMINENTLY OVER THE MIDWEST/PLAINS LATE THURSDAY THROUGH THURSDAY NIGHT DUE TO ENERGY DROPPING FROM MT/WY/DAKOTAS INTO THE BROAD TROUGH BASE. IN RESPONSE... THE DOWNSTREAM BROAD MID LEVEL TROUGHING THROUGH THE CAROLINAS WILL WEAKEN QUICKLY AS IT HEADS TO OUR NE. (THE WEAK LOW OFF FL APPEARS LIKELY TO STAY ENOUGH TO OUR SSE TO NOT BE A FACTOR IN OUR WEATHER.) THE GFS/ECMWF BRING THE SURFACE COLD FRONT TO THE WESTERN APPALACHIAN SLOPES BY LATE THURSDAY NIGHT... HOWEVER THE PUSH OF COOL AIR IMMEDIATELY BEHIND IT WILL BE MUTED WITH THE AIR MASS QUICKLY MODIFYING IN RESPONSE TO THE STRONG FRONTOGENESIS OVER THE UPPER MIDWEST. SO WHILE THE MID LEVELS WILL CONTINUE TO DRY OUT WEST TO EAST ACROSS CENTRAL NC THURSDAY NIGHT... THE REDUCTION IN SURFACE-BASED MOISTURE WILL BE MUCH MORE SUBTLE. AS SUCH... EXPECT A MINIMAL DIP IN TEMPS. LOWS THURSDAY NIGHT 66-71. FOR FRIDAY/FRIDAY NIGHT: THE FRONT APPROACHING FROM THE NW EARLY FRIDAY WILL HAVE LOST MOST OF ITS STEAM AS THE AIR MASS BEHIND IT MODIFIES. THE LOWEST 1-2 KM WILL REMAIN MOIST ENOUGH FOR BROKEN DIURNAL CLOUDS MUCH OF THE DAY... BUT THE MID-UPPER LEVEL DRYING AND SUBSEQUENT LOWERING OF PW SHOULD GREATLY LIMIT COVERAGE AND STRENGTH OF ANY CONVECTION. WITH THE ABSENCE OF MOISTURE IN THE MIXED PHASE REGION ALOFT... LIGHTNING PRODUCTION SHOULD BE MINIMAL AND EXPECT NO MORE THAN A FEW SHOWERS AT BEST FRIDAY WITH A LACK OF BOTH MOISTURE AND FORCING FOR ASCENT. THICKNESSES CHANGE VERY LITTLE AND STAY ABOVE NORMAL... SO EXPECT HIGHS OF 86-90. LOWS 65-70 WITH FAIR SKIES. FOR SATURDAY/SUNDAY: THE CANADIAN VORTEX WOBBLES SLOWLY ACROSS JAMES BAY WHILE THE TROUGH DIGS THROUGH THE CENTRAL US AND GREAT LAKES. MODEL SOLUTIONS BEGIN TO DIVERGE WITH THE ECMWF SHOWING THIS NORTHERN STREAM SEPARATING... WITH THE CANADIAN VORTEX CROSSING NRN QUEBEC... WHILE THE TROUGH STRONGLY AMPLIFIES AND CLOSES OFF ANOTHER LOW OVER THE OHIO VALLEY BY THE END OF THE WEEKEND. THE 06Z GFS ON THE OTHER HAND REMAINS PHASED AND PUSHES A POSITIVELY-TILTED TROUGH THROUGH THE NORTHEAST/APPALACHIANS/MID SOUTH... WITH A LARGE COOL FALL HIGH PRESSURE AREA CENTERED OVER THE GREAT LAKES BUILDING SOUTHEASTWARD INTO THE FORECAST AREA OVER THE WEEKEND. WHILE THE ECMWF ENSEMBLE MEAN IS MUCH MORE SUBDUED WITH THE GREAT LAKES/OHIO VALLEY TROUGHING THAN ITS OPERATIONAL COUNTERPART... THE TWO AGREE WELL ON TIMING AND PLACEMENT... AND THIS SOLUTION HAS SUPPORT FROM THE GEFS MEAN AND FROM THE NEW 12Z GFS. WILL LEAN TOWARD THE ECMWF SOLUTION. EXPECT DRY WEATHER WITH TEMPS HOLDING JUST ABOVE SEASONAL NORMALS WELL EAST OF THE TROUGH. AS THIS TROUGH MOVES EASTWARD INTO THE MID SOUTH REGION AND APPROACHES NC... WILL BRING IN A SMALL CHANCE OF STORMS LATE SUNDAY... ALONG WITH WARM TEMPS. -GIH && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... AS OF 145 AM SUNDAY... 24 HOUR TAF PERIOD: SCATTERED SHOWERS AND TSTMS ACROSS THE CENTRAL PORTION OF THE STATE ATTM WILL RESULT IN LOCALLY REDUCED CIGS AND VSBY ALONG WITH BRIEF GUSTY SFC WINDS. THE TAF SITES MOSTLY LIKELY TO BE AFFECTED WITH IFR CONDITIONS THROUGH 20Z INCLUDE KRDU AND KFAY. KINT/KGSO/KRWI MAY BE IMPACTED LATER THIS AFTERNOON AS THIS ACTIVITY CONTINUES TO EVOLVE. OUTSIDE OF THESE STORMS...EXPECT VFR CONDITIONS. LATER TONIGHT... ENHANCED LOW LEVEL MOISTURE MAY SET THE STAGE FOR A BRIEF PERIOD OF REDUCED VSBY AND CIGS WITH FOG AND LOW CLOUDS POSSIBLE TOWARD SUNRISE MONDAY. OUTLOOK: SCATTERED AFTERNOON AND EARLY EVENING SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE EACH DAY AS ENHANCED MOISTURE AND A SLOW MOVING FRONT GRADUALLY MOVE ACROSS THE REGION. ALTHOUGH FLT CONDITIONS ARE EXPECTED TO BE VFR MOST OF THIS TIME...ANY SHOWER/TSTM ACTIVITY AND/OR EARLY MORNING FOG AND STRATUS WILL BE CAPABLE OF PRODUCING PERIODS OF REDUCED CIGS AND VSBY. && .RAH WATCHES/WARNINGS/ADVISORIES...
