NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jul 9, 7:07 PM EST, 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 807 PM EDT FRI JUL 9 2010 .SYNOPSIS... AN UPPER LEVEL LOW PRESSURE SYSTEM LOCATED OFFSHORE OF THE CAROLINAS WILL LIFT OFF TO THE NORTH TONIGHT. A COLD FRONT WILL MOVE INTO THE CAROLINAS ON SATURDAY AFTERNOON AND THEN MOVE TOWARD THE COAST SUNDAY MORNING. && .NEAR TERM /THROUGH TONIGHT/... AS OF 230 PM FRIDAY... DEVELOPING CONVECTION ON THE EASTERN SLOPES IS EXPECTED TO MOVE SOUTHEAST INTO THE WESTERN PIEDMONT THIS EVENING. NAM AND LOCAL WRF MODEL HINT THAT THIS ACTIVITY COULD PERSIST TOWARDS MIDNIGHT. ELSEWHERE...INSTABILITY IS STRONG WITH ML CAPES EXCEEDING 2K JOULES...BUT CLOUD COVERAGE HAS LIMITED INSOLATION AND THE WEAK LEE TROF PROVIDES LITTLE CONVERGENCE TO HELP TRIGGER ACTIVITY. THE BANDED CONVECTION ASSOCIATED WITH THE COASTAL LOW HAS STALLED ON THE NORTHEAST FRINGE OF THE CWFA AND WILL AFFECT ONLY A SLIVER OF THE AREA AS THAT LOW LIFTS NORTH. SO...OUTSIDE OF THE WESTERN PIEDMONT CONVECTION WILL BE MORE SCATTERED DUE TO WEAK MID LEVEL RIDGING PINCHED BETWEEN THE APPROACHING UPPER TROF AND THE COASTAL UPPER LOW NORTH OF HATTERAS. WILL HAVE CHANCE POPS RANGING AS HIGH AS 50 PERCENT THROUGH EARLY TONIGHT IN THE WEST. TONIGHT...CLOUD COVERAGE WILL INCREASE AND THE LEE TROF OVER THE AREA WILL STRENGTHEN AHEAD OF A COLD FRONT WHICH WILL REACH THE WESTERN CWFA TOWARDS SUNRISE. DYNAMIC SUPPORT IS WEAK...BUT VERY MOIST AIRMASS WILL NOT NEED A BIG SQUEEZE TO PRODUCE SHOWERS...WILL HAVE SLIGHT CHANCE POPS FROM AROUND MIDNIGHT THROUGH THE NIGHT...INCREASING IN THE WEST TOWARDS SUNRISE WHEN STRONGER CONVERGENCE ASSOCIATED WITH THE H85 TROF REACHES THAT AREA. LOWS WILL BE VERY MILD DUE TO CLOUD COVERAGE AND WEAK SOUTHWEST FLOW...LOW AND MID 70S. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... AS OF 240 PM FRIDAY... A COLD FRONT WILL MOVE SLOWLY ACROSS THE AREA TOMORROW...PRODUCING DECENT CHANCES FOR WIDESPREAD RAIN. MODELS DIFFER IN TIMING...WITH THE GFS RUSHING THE FRONT EAST AND KEEPING US ALMOST DRY... CONTASTING THE SLOWER NAM AND EUROPEAN. WITH THE MOIST AIRMASS IN PLACE...AM INCLINED TO THINK WE WILL HAVE DECENT COVERAGE AND WILL USE THE SLOWER TIMING WHICH IS ALSO SIMILAR TO OUR ONGOING FORECAST TREND. THERE ARE A COUPLE OF FACTORS WHICH ARE WORKING AGAINST US...CLOUD COVERAGE WILL BE HEAVIER THAN PREVIOUS DAYS...LIMITING HIGHS TO MID 80S TO LOWER 90S AND OUR UPPER SUPPORT WILL BE SORELY LACKING AS WELL...WITH THE UPPER JET INITIALLY NORTHWEST OF THE AREA TRANSLATING SOUTHEAST WHICH LEAVES US WITH INCREASING SPEEDS DURING FROPA. THE FRONT WILL MOVE EAST OF THE AREA EARLY TOMORROW NIGHT...WITH POPS ENDING FROM THE WEST BY MIDNIGHT WITH A CLEARING TREND IN THE SKY COVERAGE. NOT MUCH OF AN AIRMASS CHANGE BEHIND THE FRONT AND SATURDAY NIGHT MINS WILL BE ONLY MARGINALLY COOLER...WITH LOW LEVEL THICKNESSES > 1400M...UPPER 60S WITH SOME LOWER 70S IN THE EAST WHERE CLOUD COVERAGE LINGERS. && .LONG TERM /SUNDAY THROUGH THURSDAY/... AS OF 230 PM FRIDAY... SUNDAY...THE COLD FRONT WILL BE NEAR THE SOUTHEASTERN PORTION OF THE FORECAST AREA EARLY ON SUNDAY. THEREFORE...THIS COULD PROVIDE A TRIGGER FOR CONVECTION AND WILL MAINTAIN THE SLIGHT CHANCE POPS ACROSS THE SOUTHEAST. OTHERWISE...PARTLY TO MOSTLY SUNNY SKIES ARE EXPECTED AND LOW LEVEL THICKNESS VALUES TRANSLATE TO HIGHS IN THE LOWER 90S. SUNDAY NIGHT THROUGH MONDAY NIGHT...THE FRONT IS EXPECTED TO BE SOUTHEAST OF CENTRAL NORTH CAROLINA BY SUNDAY NIGHT. THEREFORE... MAINLY DRY CONDITIONS ARE EXPECTED FOR THE SUNDAY NIGHT THROUGH MONDAY NIGHT TIME FRAME. HOWEVER...CANNOT RULE OUT AN ISOLATED THUNDERSTORM DURING THIS PERIOD...MAINLY ACROSS THE SOUTHERN AND WESTERN PORTIONS OF THE FORECAST AREA WITH THE FORCING BEING THE FRONT TO THE SOUTH AND DIFFERENTIAL HEATING/UPSLOPE IN FOOTHILLS. NEVERTHELESS...DECIDED TO LEAVE THE FORECAST DRY FOR NOW BECAUSE COVERAGE SHOULD BE VERY LIMITED IF AT ALL. HEIGHTS ARE PROGGED TO RISE SLIGHTLY...WHICH WILL INCREASE OUR THICKNESS VALUES FROM SUNDAY'S VALUES. THEREFORE...MONDAY SHOULD BE A COUPLE OF DEGREES WARMER...WITH HIGHS IN THE LOW TO MID 90S EXPECTED. OVERNIGHT LOWS SHOULD RANGE FROM THE UPPER 60S ACROSS THE NORTHWEST TO THE LOWER 70S FURTHER SOUTH AND EAST. TUESDAY THROUGH FRIDAY...ANOTHER SHORTWAVE TROUGH IS PROGGED TO MOVE ACROSS THE GREAT LAKES REGION AND AN ASSOCIATED SURFACE LOW/FRONT SHOULD AFFECT THE REGION DURING THIS TIME FRAME. WITH THE TROUGH ALOFT AND THE SLOW MOVING SURFACE BOUNDARY...AS WELL AS INCREASED MOISTURE AND INSTABILITY...WILL ALL RESULT IN AT LEAST CHANCE POPS THROUGH MOST OF THE PERIOD...WITH THE BEST CHANCE OCCURRING ON TUESDAY AND WEDNESDAY. MOST OF THE CONVECTION SHOULD BE DIURNALLY DRIVEN...THEREFORE...POPS WILL BE CONFINED TO THE AFTERNOON AND EARLY EVENING HOURS. BY FRIDAY...MODELS ARE STARTING TO HINT AT THE RIDGE BEGINNING TO BUILD EASTWARD AGAIN...WHICH WOULD RESULT IN DRIER CONDITIONS AND EVEN WARMER TEMPS. OVERALL...AFTERNOON HIGHS ARE EXPECTED TO BE IN THE LOW TO MID 90S...WITH OVERNIGHT LOWS IN THE LOW MID 70S. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... AS OF 805 PM FRIDAY... VFR CONDITIONS SHOULD PREVAIL ACROSS CENTRAL NORTH CAROLINA THROUGH THE TAF PERIOD. PRIMARY AVIATION CONCERNS WILL BE BRIEF MVFR/IFR VISIBILITY AND CEILINGS IN ANY SHOWERS OR THUNDERSTORMS. PERSISTENT MVFR HAZE TOWARD KGSO WILL LIKELY CONTINUE UNTIL SOME MIXING AFTER SUNRISE SATURDAY. IT IS POSSIBLE THAT OTHER AREAS COULD EXPERIENCE MVFR HAZE OR LIGHT FOG IN THE MOIST AIR MASS LATE TONIGHT...BUT EXPECTED DEGREE OF MID- AND HIGH-LEVEL CLOUD COVER SHOULD KEEP SUCH CONDITIONS FROM DETERIORATING TO IFR. EXPECT AN AREA OF SHOWERS TO MOVE THROUGH CENTRAL NORTH CAROLINA DURING THE MORNING ASSOCIATED WITH LIFT...DEEPER MOISTURE ON MODEL SOUNDINGS...AND THE PASSAGE OF A MID-LEVEL SHORTWAVE. DEEPER LIFT IS FOCUSED CENTRAL AND EAST SATURDAY AFTERNOON AND OPTED TO INTRODUCE A PERIOD OF TEMPO TS FOR KFAY AND KRWI WHERE THE COMBINATION OF LIFT... MOISTURE...AND INSTABILITY APPEARS GREATEST. BEYOND THE 00Z TAF PERIOD...AS DRIER AIR ONLY SLOWLY MOVES IN FROM THE NORTHWEST SATURDAY NIGHT...THERE WILL BE THE POSSIBILITY OF MVFR FOG TOWARD KFAY AND KRWI. SUNDAY AND MONDAY...PRIMARY AVIATION CONCERN SHOULD BE MVFR MORNING FOG POSSIBLE TOWARD KFAY AND KRWI...AND AN ISOLATED THUNDERSTORM SUNDAY AFTERNOON NEAR THE SAME TERMINALS. DEEPER MOISTURE WILL RETURN FOR TUESDAY AND WEDNESDAY. THIS WILL INCREASE ONCE AGAIN THE CHANCES FOR MAINLY AFTERNOON AND EVENING THUNDERSTORMS. && .RAH WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...BSD NEAR TERM...MLM SHORT TERM...MLM LONG TERM...KRR AVIATION...DJF
