AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 424 PM EDT WED AUG 8 2007 .SYNOPSIS... A STRONG UPPER LEVEL RIDGE WILL EXTEND FROM THE MISSISSIPPI VALLEY EASTWARD INTO THE SOUTHEAST U.S. THROUGH LATE THURSDAY. A COLD FRONT WILL MOVE ACROSS THE REGION LATE FRIDAY RESULTING IN SLIGHTLY COOLER TEMPERATURES FOR THE WEEKEND. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... AS OF 300 PM RDU HAD TIED THE PREVIOUS RECORD HIGH OF 101 AND GSO REACHED 100 BREAKING THE OLD RECORD HIGH OF 100. HEAT INDICES REACHED 110 ACROSS MUCH OF THE COASTAL PLAIN AND EASTERN PORTIONS OF THE PIEDMONT THIS AFTERNOON. ISOLATED CONVECTION ONGOING ACROSS LOCATIONS EAST OF THE PIEDMONT TROUGH. THIS ACTIVITY IS UNORGANIZED AND SHOULD DIMINISH QUICKLY AFTER SUNSET. OUTSIDE OF THUNDERSTORMS...TEMPERATURES WILL SLOW TO FALL TONIGHT...EVENTUALLY MAKING IT INTO THE MID TO UPPER 70S. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... UPPER RIDGE REMAINS IN PLACE THROUGH LATE THURSDAY BEFORE BREAKING DOWN LATE FRIDAY. THIS WILL RESULT IN HOT CONDITIONS. THURSDAY SHOULD BE SIMILAR TO WEDNESDAY WEATHER WITH A TROUGH SETTING UP ALONG THE PIEDMONT FALL LINE. DEWPOINTS WEST OF THE TROUGH WILL DROP INTO THE UPPER 60S DURING THE AFTERNOON. WITH A LOCAL MAX TEMP FORECASTING SCHEME...WHICH HAS WORKED WELL PAST FEW DAYS... GIVING HIGHS IN THE 98 TO 101 RANGE...HEAT INDEX VALUES WILL RANGE NEAR THE 105 MARK FOR A FEW HOURS. TO THE EAST OF THE TROUGH... DEWPOINTS WILL HOLD IN THE LOW TO MID 70S THROUGH THE AFTERNOON. LOCAL SCHEME GIVES HIGHS IN THE 100 TO 104 RANGE WHICH WILL RESULT IN HEAT INDEX VALUES EASILY EXCEEDING 110. SREF ANOMALY CHARTS FOR THURSDAYS 850 MB TEMPS OVER NC ARE 3-4 STANDARD DEVIATIONS ABOVE NORMAL...CONSISTENT WITH AN EXTREME EVENT. LOWER HEIGHTS AND INCREASED CLOUD COVER SHOULD WORK TO LIMIT TEMPS ON FRIDAY. THICKNESS SCHEMES AND MOS GUIDE SUGGEST MAX TEMPS FRIDAY WILL BE A SHADE COOLER THAN THURSDAY BUT SOUTHERN AND EASTERN LOCATIONS STILL HAVE A FAIR CHANCE TO REACH EXCESSIVE HEAT CRITERIA. LOWER HEIGHTS AND INCREASED CLOUD COVER SHOULD WORK TO LIMIT TEMPS. LONGEVITY OF THE EVENT SUGGEST THAT A EXCESSIVE HEAT WATCH IS WARRANTED EVEN THOUGH MEETING EXCESSIVE HEAT CRITERIA IS NOT GUARANTEED. WITH H5 RIDGE EASING WESTWARD...LATER SHIFTS WILL NEED TO MONITOR THE POTENTIAL FOR A NOCTURNAL CONVECTIVE COMPLEX OVER THE OH VALLEY THU NIGHT TO MOVE ACROSS THE AREA EARLY FRIDAY. AFTERNOON CONVECTION IS EXPECTED AHEAD OF SFC FRONT FRIDAY WITH GREATEST COVERAGE EXPECTED ACROSS E AND NE PORTIONS OF FORECAST AREA. AIRMASS COOLS NOTICEABLY ON SATURDAY WITH 850 MB TEMPS DROPPING SIGNIFICANTLY. STILL A CHANCE OF CONVECTION ACROSS THE SOUTHERN COASTAL PLAIN AND SANDHILL SON SAT BEFORE UPPER TROUGH MOVES THROUGH. WITH COOLER AIRMASS AND MORE CLOUDINESS...TEMPERATURES SHOULD HOLD NEAR 90 ON SATURDAY. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE GFS AND CANADIAN DROP A SHORTWAVE TROUGH SOUTHEAST THROUGH CENTRAL/EASTERN NC LATE SATURDAY... AND WILL HOLD ONTO A SMALL EVENING POP IN THE SOUTHEAST. OTHERWISE THIS WEEKEND WILL FEATURE A DRYING TREND WITH LIMITED OPPORTUNITIES FOR RAIN THROUGH MID WEEK. WILL HAVE A RETURN TO NEAR NORMAL TEMPERATURES AS SURFACE HIGH PRESSURE BUILDS IN BEHIND THE FRONT WITH SHORTWAVE RIDGING IN THE MID LEVELS. HOWEVER... THIS IS A NORTHERN ROCKIES SOURCE HIGH WITH A LONG VOYAGE... AS OPPOSED TO A NOTABLY COOLER AIR MASS FRESH OUT OF NORTHERN CANADA... SO HIGHS SHOULD REMAIN CLOSE TO NORMAL THROUGH TUESDAY WITH LOWS SLIGHTLY BELOW NORMAL EARLY IN THE PERIOD RISING TO NEAR NORMAL. BY TUESDAY NIGHT AND WEDNESDAY ANOTHER SHORTWAVE DROPS SOUTHEAST INTO THE MID-ATLANTIC REGION AND REESTABLISHES THE MID-UPPER LEVEL WEAKNESS DOWN THE EAST COAST... AND THIS SHOULD LEAD TO A RETURN TO THE POSSIBILITY OF ISOLATED LATE DAY STORMS... ALTHOUGH MOISTURE AVAILABILITY SHOULD REMAIN LIMITED. -GIH && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... WITH NO SIGNIFICANT CHANGE IN WEATHER REGIME... TERMINAL FORECASTS LARGELY FOLLOWED PERSISTENCE. INT/GSO SHOULD HAVE VFR VISIBILITIES THROUGH THIS EVENING WHILE MVFR HAZE SHOULD PERSIST AT THE REMAINDER OF TAF SITES. CONSIDERING THE DROP TO IFR VISIBILITIES AT RWI AND FAY THIS MORNING... HAVE INCLUDED THIS AGAIN TONIGHT WITH A STAGNANT MOIST AIR MASS AND WEAK WIND FLOW. THESE SHOULD IMPROVE TO MVFR HAZE THURSDAY MORNING. NO CIGS OR BRIEFLY VFR CIGS THROUGH THE PERIOD. WINDS AT OR LESS THAN 7 KTS WITH NEARLY CALM CONDITIONS OVERNIGHT. TAF SITES... PARTICULARLY RDU/RWI/FAY... COULD SEE A FEW STORMS LATE THURSDAY/THURSDAY EVENING AND AGAIN FRIDAY AFTERNOON/NIGHT INTO SATURDAY MORNING... AND THESE COULD PRODUCE LOCAL MVFR VISIBILITIES AND CIGS. OTHERWISE... ASIDE FROM LATE NIGHT/EARLY MORNING MVFR FOG AND HAZE AT RDU/RWI/FAY THROUGH SATURDAY MORNING... NO OTHER HAZARDOUS AVIATION CONDITIONS ARE EXPECTED. -GIH && .CLIMATE...
