Area forecast discussion, Sep 28, 2:25 PM EDT, 3 hours 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 225 PM EDT THU SEP 28 2006 .SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/... TONIGHT: THE VIGOROUS VORTICITY MAX CURRENTLY DIVING THROUGH THE MO BOOTHEEL AND WESTERN TN/KY IS ON PACE TO SWEEP THROUGH NC THROUGH THE EARLY OVERNIGHT HOURS ACCOMPANIED BY A STRONG SURFACE FRONT. WHILE HAIL CANT BE RULED OUT WITH JUST ENOUGH MOISTURE AND INSTABILITY ALOFT... STRONG WINDS REMAIN THE BIGGER RISK IN THIS HIGH-SHEAR LOW-CAPE REGIME. LOW LEVEL LAPSE RATES ARE ALREADY 7.5-8.0 C/KM... THE DOWNDRAFT CAPE HAS RISEN TO 500-900 J/KG... AND DEEP LAYER SHEAR OF 55-65 KT IS RIGHT ON OUR DOORSTEP... SO DAMAGING DOWNBURST WINDS REMAIN A GOOD POSSIBILITY THIS EVENING... ESPECIALLY IF NAM-WRF INDICATIONS OF A FAIRLY DEEP STRATOSPHERIC INTRUSION COME TO PASS. AND IF WE GET ANY CONTRIBUTION FROM DOWNSLOPE FLOW TO FURTHER STEEPEN LAPSE RATES... THE STRONG TO DAMAGING WIND THREAT COULD BECOME WIDESPREAD. A SEVERE WEATHER OUTLOOK WAS ISSUED EARLIER THIS AFTERNOON TO ADDRESS THIS. WITH PRECIPITABLE WATER VALUES BARELY UP TO ONE INCH AND WITH THE SWIFT TRANSLATIONAL SPEED OF THE EXPECTED CONVECTIVE LINE... DONT EXPECT ANY MORE THAN ABOUT A HALF INCH OF RAIN AT ANY GIVEN SPOT. WILL STILL CARRY MAXIMUM POPS OF 70-80% ACROSS THE NORTH WITH 50-70% IN THE SOUTH FROM VERY LATE THIS AFTERNOON UNTIL SHORTLY AFTER MIDNIGHT. EXPECT LOWS OF 54-61. FRIDAY THROUGH SUNDAY: WILL CARRY A LOW CHANCE OF SHOWERS IN THE NORTHEAST EARLY FRIDAY MORNING AS THE VORTICITY MAX ROTATES NORTHEAST AND OUT OF THE STATE... OTHERWISE EXPECT CLEARING SKIES. THICKNESSES SUPPORT TEMPERATURES WELL BELOW NORMAL... MAINLY 68-73. A MUCH WEAKER WAVE WILL SWING BY TO OUR NORTH DURING THE AFTERNOON WITH NO MOISTURE TO WORK WITH AND DOWNSLOPE FLOW EAST OF THE MOUNTAINS. OTHERWISE A SURFACE HIGH PASSES OVER THE REGION THROUGH SATURDAY... AND EXPECT CHILLY LOWS IN THE 40S FRIDAY NIGHT. THE NEXT STRONG MID LEVEL VORTICITY MAX AND CANADIAN COLD FRONT DIVE DOWN LATE SATURDAY NIGHT AND SUNDAY MORNING... BUT THIS TOO WILL HAVE LITTLE MOISTURE TO WORK WITH. HAVE ELECTED TO LEAVE IN THE EXISTING SLIGHT CHANCES OF SHOWERS ACROSS THE NORTH HALF... ENDING BY SUNDAY AFTERNOON. EXPECT HIGHS OF 70-75 SATURDAY AND MID-UPPER 70S SUNDAY. -GIH && .LONG TERM /MONDAY THROUGH THURSDAY/... GENERALLY DRY THROUGH THIS PERIOD. UPPER RIDGE/SURFACE HIGH WILL DOMINATE OVER EASTERN CONUS AT START OF PERIOD. RIDGE WILL FLATTEN BY MID WEEK WITH SURFACE HIGH SHIFTING SOUTH AND SOUTHWEST. DURING MID/LATE WEEK...S/W TROUGH AND BACKDOOR FRONT MOVING ACROSS THE AREA. SURFACE AND 850 FLOW WEST/NORTHWEST WITH STRONGEST DYNAMICS STAYING NORTH OF AREA. THUS SEE LITTLE CHANCE FOR RAIN. GFS INDICATING DEEPER POST FRONTAL MOISTURE OVER THE AREA AS LOW LEVEL WINDS TURN NORTHEAST. FOR NOW WILL INDICATE PARTLY CLOUDY FOR THURSDAY. WARM TEMPERATURES MUCH OF THE PERIOD WITH MAX TEMPERATURES AVERAGING ABOUT 5-8 DEGREES ABOVE SEASONAL NORMS THROUGH MID WEEK. THEN COOL DOWN ON THURSDAY AS MENTIONED... LOW LEVEL WINDS TURN NORTHEAST AND MORE CLOUDS. -RA && .AVIATION... SCATTERED TO BKN CU 4-6KFT THROUGH 00Z. ISOLATED SHOWERS POSSIBLE FAY-GSB THROUGH 00Z.
