DISCUSSION
KEY MESSAGE 1: FRONTAL BOUNDARY PROVIDES SHOWER/FEW STORM
CHANCES TONIGHT INTO THURSDAY.
A SWITCH TO MORE ZONAL FLOW ALOFT ADVECTS AN ELONGATED MOISTURE AXIS
AND CORRESPONDING FRONTAL BOUNDARY IN ACROSS THE NORTHERN HALF OR SO
OF THE CWA FOR THURSDAY. THIS WILL ALLOW FOR THE RETURN OF PRECIP
CHANCES. IT SHOULD PRIMARILY BE SCATTERED SHOWERS SINCE INSTABILITY
SHOULD BE LACKING. AS OF 730 PM EDT, PROGRESSION OF SHOWERS AND
STORMS ARE A FEW HOURS AHEAD OF SCHEDULE. AS SUCH, OUR LATEST
FORECAST UPDATE WILL REFLECT A SLIGHTLY EARLY ARRIVAL FROM
BLUEFIELD TO LEWISBURG LATE THIS EVENING.
KEY MESSAGE 2: STRONG FRONT LATE FRIDAY TO BRING BLUSTERY WINDS
AND MUCH COOLER TEMPERATURES GOING INTO THE WEEKEND.
WE QUICKLY TRANSITION OUT OF THE ZONAL FLOW WITH THE APPROACH OF A
HIGH AMPLITUDE UPPER TROUGH AND SHARP ATTENDANT SFC COLD FRONT LATE
FRIDAY INTO SATURDAY. NOT EXPECTING MUCH IN THE FORM OF STORMS WITH
AGAIN LIMITED INSTABILITY WITH THIS SYSTEM AND THE GREATER CHANCE OF
SHOWERS LOOKS TO BE IN THE WEST MOUNTAINS. THE MAIN IMPACTS FROM
THIS FRONT WILL BE ENHANCED GRADIENT WINDS KICKING IN FOR FRIDAY
NIGHT INTO SATURDAY MORNING AND THEN SOME OF THE COLDEST AIR OF THE
SEASON USHERING IN. IT WILL DEFINITELY FEEL LIKE A ROLLERCOASTER OF
CHANGE AS HIGHS SATURDAY LOOK TO BE MAINLY IN THE LOW 50S FOR MUCH
OF THE MOUNTAINS AND THEN UPPER 50S TO LOW 60S FOR THE PIEDMONT.
SUNDAY MORNING IS GOING TO HAVE FROST/FREEZE CONCERNS FOR MUCH OF
THE AREA WITH PROGGED LOWS MAINLY IN THE UPPER 20S TO LOW 30S FOR
THE MOUNTAINS AND MID TO UPPER 30S FOR THE PIEDMONT. THIS COULD
AGAIN BE THE CASE FOR MONDAY MORNING AS WELL.
AVIATION /06Z THURSDAY THROUGH MONDAY/
VFR CONDITIONS CURRENTLY PREVAIL ACROSS MUCH OF THE REGION.
HOWEVER, SHOWERS AND SUB-VFR CIGS ARE APPROACHING THE MOUNTAINS
AND WITH THE FRONT DRIVING SOUTHWARD TODAY MODELS HAVE CIGS
LOWERING THROUGH INTO 12Z, WITH GOOD POTENTIAL FOR IFR OR LOWER
CIGS AT MOST TERMINALS THROUGH THE REST OF THE PERIOD AS THE
FLOW TURNS NORTHEAST TO EAST. SHOWERS WILL IMPACT VSBYS AT TIMES
MORE-SO ACROSS LWB THIS MORNING.
BLF WILL LIKELY IMPROVE BACK TO VFR BY THURSDAY AFTERNOON.
EXTENDED AVIATION OUTLOOK...
WITH A STALLED BOUNDARY FOLLOWED BY A STRONG COLD FRONT, SOME
SUB-VFR CONDITIONS ARE POSSIBLE THURSDAY NIGHT AND FRIDAY.
BEHIND THE FRONT FRIDAY NIGHT INTO SATURDAY MORNING, LOOK FOR
AN ABRUPT WIND SHIFT TO THE NORTHWEST AND GUSTY CONDITIONS AT
THE SURFACE. THESE STRONGER WINDS SHOULD GRADUALLY VEER NORTH
AND DECREASE THROUGH THE DAY SATURDAY. DRY WEATHER AND VFR
CONDITIONS ARE EXPECTED INTO SUNDAY AND MONDAY.
