Area forecast discussion, Sep 20, 12:15 PM EST, 7 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 115 PM EDT TUE SEP 20 2005 .SHORT TERM (TONIGHT THROUGH FRIDAY)... VORTICITY CENTER NOW CROSSING THE MOUNTAINS WILL MOVE OVER AN UNSTABLE AIR MASS IN THE PIEDMONT THIS EVENING...INITIATING SHOWERS AND THUNDERSTORMS. EXPECT THAT STORMS WILL DEVELOP AS LAPSE RATES STEEPEN AND BOUNDARY LAYER CONVERGENCE INCREASES AS SHOWN IN THE RUC. CONVECTIVE PARAMETERS INDICATE SOME SEVERE POTENTIAL WITH STRAIGHT LINE WINDS BEING THE MAIN THREAT. THE LACK OF DEEP MOISTURE WILL LIKELY LIMIT TSTM COVERAGE TO SCATTERED. THE ENERGY ASSOCIATED WITH THE VORTICITY CENTER SHOULD HELP SUSTAIN CONVECTION OVERNIGHT. GFS AND NAM DISAGREE ON THE PLACEMENT OF THE RESIDUAL SURFACE FRONT AND ASSOCIATED MOISTURE ON WEDNESDAY. THE NAM HAS A STRONGER MIDWEST RIDGE WHICH PUSHES ALL MOISTURE OFFSHORE. THE GFS HAS A WEAKER FLOW ALOFT AND KEEPS MOISTURE AND LIFT OVER OUR SOUTHEAST SECTIONS THROUGH THURSDAY. THE GFS SEEMS TO BE WEAKENING THE RIDGE TOO FAST AND THE NAM IS PREFERRED. WILL MAINTAIN A SLIGHT CHANCE SOUTHEAST ON WEDNESDAY BUT DROP ALL POPS AFTER WEDNESDAY NIGHT. WILL ALSO LEAN TOWARD THE WARMER MET MOS TEMPERATURES...WHICH HAVE UPPER 80S IN MOST SPOTS WEDNESDAY AND THURSDAY. ON FRIDAY THE MIDWEST RIDGE PROGRESSES EAST...AND WILL BE CENTERED OVER THE AREA. THIS WILL BRING TEMPS UP TO THE LOWER 90S IN MOST SPOTS. && .LONG TERM (FRIDAY NIGHT THROUGH TUESDAY)... FRI NGT-SAT...A WEAK COLD FRONT MAKES A RUN AT US FROM THE NORTH... BUT CONDITIONS REMAIN RELATIVELY STABLE AND DRY BENEATH THE STRONG SUBTROPICAL RIDGE ALOFT. A SWITCH TO NORTHERLY WINDS WILL ADVECT SOMEWHAT COOLER AIR INTO THE REGION BY SAT. LOWS 64-68. HIGHS 83-87. SAT NGT-SUN...SURFACE HIGH PRESSURE RIDGES DOWN THE COAST FROM NEW ENGLAND WITH PREDOMINANT NE FLOW OVER THE AREA. STRONG RIDGING CONTINUES ALOFT WITH SUBSIDENCE WARMING HELPING TO KEEP TEMPERATURES ABOVE SEASONAL NORMS. LOWS 61-66. HIGHS 82-87. SUN NGT-TUE...MUCH DEPENDS ON THE RESIDUALS FROM RITA AND WHETHER THEY GET SWEPT UP BY A STRONG COLD FRONT. THERE IS A LACK OF CONTINUITY FROM RUN TO RUN IN THE VARIOUS MEDIUM RANGE MODELS AND THE GFS MAY BE SMEARING GRID SCALE MOISTURE TOO FAR EAST TOO QUICKLY. THUS...A WARM DRY FORECAST IS PREFERRED AT THIS TIME BUT WITH SOME INDICATIONS OF INCREASING MOISTURE AND CLOUDINESS. LOWS 62-66. HIGHS 82-86. -RFG && .AVIATION... ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED 20-02Z WITH BRIEF MVFR CIGS AND VSBY. OTHERWISE VFR CONDITIONS ARE EXPECTED THROUGH 06Z. AFTER 06Z...WEAK FLOW IN THE LOWER LEVELS WITH RESIDUAL LOW LEVEL MOISTURE WILL LEAD TO AREAS OF STRATUS AND FOG...CAUSING LOCALLY IFR CIGS AND VSBY AROUND DAYBREAK. -RFG && .RAH WATCHES/WARNINGS/ADVISORIES...
