&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
AS OF 1245 AM EST...STEADY PRECIP HAS TAPERED OFF ACROSS THE
AREA...HOWEVER SPOTTY FREEZING DRIZZLE OR LIGHT SLEET STILL

.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/...
THE PRECIPITATION IS EXPECTED TO TAPER OFF EARLY WEDNESDAY WITH
THE COLD FRONT SLIDING SOUTH AND EAST OF THE FA. EXPECT CLOUDS
MIXED WITH SOME SUN HIGHS WEDNESDAY ARE EXPECTED TO BE IN THE 3OS
TO LOWER 40S...DEPENDING ON HOW MUCH MIXING WE GET WITH THE
WINDS...HOW MUCH SUN...AND IF THE COLD FROZEN SNOW COVERED GROUND
COULD LIMIT THE SURFACE WARMING.

A WAVE OF LOW PRESSURE IS EXPECTED TO FORM ALONG THE COLD FRONT
SOUTH AND EAST OF OUR REGION AND BRING SNOW BACK ACROSS OUR
SOUTHERN 6 COUNTIES CONSISTING OF GREENE...COLUMBIA...BERKSHIRE...
ULSTER...DUTCHESS AND LITCHFIELD LATE WEDNESDAY INTO THURSDAY.
THERE IS STILL CONSIDERABLE UNCERTAINTY AS TO HOW FAR NORTH ANY
AREAS OF SNOW CAN GET...SO INCLUDING CHANCES TO LIKELY POPS ACROSS
THE AFOREMENTIONED AREAS. THERE COULD BE 2 TO 4 INCHES OF SNOW IN
SOUTHERN AREAS WEDNESDAY NIGHT INTO THURSDAY MORNING. THIS LOW

TEMPERATURES WILL ONCE AGAIN BE COLD FOR FRIDAY NIGHT INTO
SATURDAY MORNING WITH LOWS IN THE SINGLE DIGITS. WITH A STORM
SYSTEM APPROACHING FROM THE GREAT LAKES REGION...THERE WILL BE A
W-SW FLOW AT LOW AND MID LEVELS. THIS SHOULD ALLOW TEMPS TO
MODERATE FOR SATURDAY...WITH HIGHS IN THE UPPER 20S TO MID 30S
OVER THE REGION. SOME SNOW SHOWERS AND FLURRIES WILL BE POSSIBLE
BETWEEN LATE FRIDAY NIGHT AND SATURDAY NIGHT...BUT MAINLY FOR
WESTERN AND NORTHERN PARTS OF THE REGION. EVEN AREAS THAT SEE SNOW

LACKING WITH THIS NORTHERN STREAM CLIPPER SYSTEM.

NORMAL LEVELS. ANOTHER MOISTURE STARVED CLIPPER SYSTEM COULD
APPROACH FOR MONDAY...OTHERWISE...IT LOOKS FAIRLY DRY...WITH NO
MAJOR SYSTEMS IMPACTING THE REGION THROUGH THE START OF THE WEEK.
HIGHS FOR MON/TUES LOOK TO BE IN THE 30S...WITH TEENS AND 20S AT

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
MAIN PRECIPITATION SHIELD HAS MOVED OFF WELL TO OUR EAST. HOWEVER
WE HAVE LOST ICE IN THE CLOUDS AND ARE GETTING FREEZING DRIZZLE

TEMPERATURES.  TEMPERATURES WILL GRADUALLY RISE THIS MORNING AS
THE LOW PRESSURE SYSTEM APPROACHES AND MOVES ACROSS THE REGION.
THE SYSTEM`S FRONTAL BOUNDARY WILL MOVE ACROSS THE REGION AROUND
12Z/WEDNESDAY, WIDESPREAD MVFR CONDITIONS WILL PERSIST WITH IFR
POSSIBLE. AN IMPROVEMENT TO VFR IS EXPECTED BY LATE THIS MORNING.
HIGHER LEVELS CLOUDS WILL MOVE BACK IN ACROSS THE AREA AS THE
LOWER  AND MID LEVEL CLOUDS BREAK THIS AFTERNOON. MID AND LEVEL
CLOUD COVER WILL RETURN AS A WAVE OF LOW PRESSURE MOVES ALONG THE
COLD FRONT BOUNDARY TO OUR SOUTH. THE PRECIPITATION SHIELD ASSOCIATED
WITH THIS LOW IS EXPECTED TO ONLY IMPACT KPOU WITH SOME LIGHT SNOW
MAINLY AFTER 06Z/THURSDAY.

SOUTHERLY WINDS WILL REMAIN STRONGEST AT KALB AND KPSF WITH GUSTS THIS
MORNING. WIND WILL SHIFT TO THE WEST WITH PASSAGE OF THE COLD FRONT
THIS MORNING AND WILL BECOME GUSTY INTO THE TEENS AND 20S WITH THE
STRONGEST WINDS AT KALB AND KPSF. WINDS WILL DECREASE AND LOSE THEIR

DAYS. HOWEVER...ANOTHER STORM SYSTEM WILL IMPACT THE REGION
THROUGH TONIGHT...WITH THE POSSIBILITY OF SNOW...MIXED
PRECIPITATION AND/OR RAIN.

A BRIEF WARMUP MAY OCCUR ON WEDNESDAY...BUT THE SHORT TIMING AND
MAGNITUDE OF THE WARMTH WILL LIKELY NOT BE ENOUGH TO CAUSE ANY HYDRO
CONCERNS. ANOTHER COLD AIR MASS WILL BUILD IN LATE WEDNESDAY INTO
THURSDAY...WITH TEMPERATURES FALLING BACK BELOW FREEZING.
