AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 300 AM EST TUE MAR 8 2005 .SHORT TERM (TODAY THROUGH THURSDAY)... MAIN FORECAST CHALLENGE FIRST 12 HOURS AS STRONG COLD FRONT PROGGED TO CROSS REGION THIS MORNING. STRONG LOW LEVEL CONVERGENCE COUPLED WITH ENHANCED LIFT ALOFT AS FORECAST AREA IN LEFT EXIT REGION OF STJ AND IN THE RIGHT ENTRANCE OF POLAR JET AT 12Z SUGGEST WIDESPREAD SHOWER/ISOLATED T OVER LARGE PART OF CENTRAL NC.

STILL SOME CONCERN FOR ISOLATED DAMAGING WIND GUSTS AS LOW LEVEL JET OF 55-60 KTS IN VICINITY. 07Z MSAS ANALYSIS HINTS AT WEAK INSTABILITY AXIS TRYING TO DEVELOP OVER SOUTHERN COASTAL PLAIN. HOWEVER APPEARS THAT CONVECTION HUGGING FL PANHANDLE THROUGH SOUTHERN GA DISRUPTING MOISTURE TRANSPORT ENOUGH TO PREVENT AIRMASS OVER CENTRAL NC FROM REACHING BEST INSTABILITY POTENTIAL.

THUS APPEAR MAX TEMPS FOR DAYLIGHT HOURS WILL OCCUR BETWEEN 11-15Z ACROSS REGION. POPULATED TEMP GRIDS WITH GFS MOS AS IT APPEARED TO HAVE BEST FIRST GUESS.

DRY AND SEASONABLY COOL CONDITIONS PERSIST INTO THU && .LONG TERM (THURSDAY NIGHT THROUGH MONDAY)... GFS APPEARS TO BE TRENDING TOWARD A WEAKER CHANNELED VORT AXIS CROSSING ON THURSDAY NIGHT/FRIDAY...AND TOWARD LESS MOISTURE. THE NAM ALSO SHOWS LIMITED MOISTURE. WILL LOWER POPS SLIGHTLY THURSDAY NIGHT/FRIDAY. IF PRECIP CAN COME IN EARLY ENOUGH ON THURSDAY NIGHT...THICKNESSES SUGGEST SNOW ACROSS THE NORTH. WILL CONTINUE MENTION OF RAIN AND SNOW SHOWERS THURSDAY NIGHT. THICKNESSES AND SURFACE TEMPS WARM DURING THE DAY FRIDAY AND THE MENTION OF SNOW WILL BE REMOVED.
