GENERAL MODEL AGREEMENT CONTINUES THROUGH SATURDAY NIGHT. EXPECT
A SECOND COASTAL LOW TO DEVELOP OFF THE CAROLINA COAST SATURDAY
THEN SLOWLY DRIFT NORTH AND INTENSIFY TO A POSITION EAST OF THE
DELMARVA/SOUTH OF LONG ISLAND BY SUNDAY MORNING IN RESPONSE TO A
SHARPENING (AND GRADUALLY CUTTING OFF) DEEP LAYER TROUGH MOVING IN
FROM THE GREAT LAKES.
EXPECT A RELATIVE LULL IN THE PRECIPITATION (DEVELOPING FROM W TO
E DURING THE DAY ON FRIDAY AND CONTINUING INTO SATURDAY MORNING)
IN BETWEEN SYSTEMS WITH MAINLY LIGHT RAIN (LIGHT RAIN/SNOW
INTERIOR) COULD ACTUALLY END UP WITH DRIZZLE IN PLACES). SOME
PLACES MIGHT EVEN GO COMPLETELY DRY FOR A TIME...BUT TO MUCH
UNCERTAINTY TO PIN POINT AT THIS TIME. THEN EXPECT POPS TO
INCREASE FROM SW TO NE FROM SATURDAY AFTERNOON INTO SATURDAY NIGHT
(CATEGORICAL THROUGHOUT SATURDAY NIGHT).
NAM/ECMWF/CMC HAVE COLDER THERMAL PROFILES WITH THIS SECOND LOW
THAN DOES THE GFS...SO HEAVILY WEIGHED TEMPERATURE AND P-TYPE
FORECAST TOWARDS THEM. BELIEVE HAVE BEST CHANCE OF MEASURABLE WET
SNOW ACROSS FAR NW INTERIOR (MAINLY HIGHER ELEVATIONS)...NOW
LOOKING FOR 1-2 INCHES...BUT DEPENDING ON HOW TRACK PLAYS OUT
(NAM/GFS CLOSER TO COAST THAN ECMWF/SREF WITH CMC GLOBAL IN
BETWEEN)...COULD END UP WITH A BIT MORE AND MIGHT END UP NEEDING A
WINTER WEATHER ADVISORY AS A RESULT.
FOR TEMPERATURES IN THE SHORT TERM FOLLOWED A MET/MAV BLEND AT
NIGHT AND A BLEND OF COOLER NAM12 2-METER TEMPERATURES WITH A
MET/MAV BLEND DURING THE DAY. EXPECT TEMPERATURES 15-20 DEGREES
BELOW NORMAL THROUGHOUT THE SHORT TERM.
