.SHORT TERM (TONIGHT THROUGH SUNDAY)...
LOW PRES OVR THE NRN WV PANHANDLE WILL LIFT NORTH INTO SRN ONTARIO
TONIGHT WITH STRONG CDFNT SWEEPING THRU THE AREA EARLY THIS
EVENING. LATEST GFS AND RUC40 SHOWS A FORCED LINE OF CONVECTION
ACCOMPANYING FRONT AROUND 00Z. THIS LINE CAN BE SEEN ALREADY ON
REGIONAL RADARS OVER SWRN VA. MODEL GUIDANCE SHOWS THIS BAND OF
SHRA/TSRA LIFTING NORTH INTO SRN PA BY 03Z. AFTER THAT EXPECT
PARTIAL CLEARING E OF THE MTNS WITH UPSLOPE SHSN PICKING UP OVER
THE HIGHLANDS. WINTER WX ADVISORY ISSUED FOR THOSE AREAS AS FLOW
MAINLY WESTERLY NOT TOO CONDUCIVE FOR BIG SNOWS.
CYCLONIC FLOW AND CAA WILL CONTINUE TO SUPPORT MTN SHSN. A FEW
FLURRIES COULD ALSO MAKE IT EAST OF THE MTNS AS UPPER LVL ENERGY
PASSES BY AROUND H5 LOW OVER SRN ONTARION. TEMPS BACK TO
SEASONABLE NORMS.

.LONG TERM (SUNDAY NIGHT THROUGH SATURDAY)...
SUN NGT WILL FEATURE SCTD SN SHWRS CONTINUING IN THE
WEST...PRIMARILY IN THE ALLEG FRONT REGION...DUE TO WEAK U/L
IMPULSES IN THE BASE OF MAJOR TROUGH AS WELL AS UPSLOPE AND LAKE
ENHANCEMENTS. E OF THE BLUE RIDGE SHOULD REMAIN DRY.
ALTHOUGH PATTERN SHIFT IS GOING TO BE A SHOCK TO THE SYSTEM...IN
REALITY TEMPS WILL GNRLY BE AROUND NORMAL THROUGH THIS EXTENDED
PERIOD FOR LATE WINTER. HIGHS IN THE 30S AND 40S AND LOWS IN THE

BASICALLY THROUGH THIS PERIOD...AND WE SEE NO REASON FOR THIS
PATTERN TO CHANGE ANY TIME SOON. HWVR W/O ANY MAJOR SYSTEMS TO MOVE
INTO THE REGION...DO NOT SEE ANY BIG SNOW MAKERS. NEXT WEEKEND WILL
CONTINUE TO ADVERTISE A LITTLE BETTER CHANCE FOR SN SWRS HWVR DUE TO
CLIPPER SYSTEM DROPPING OUT THE GRT LKS.
