640 AM EST FRI APR 4 2003

.DISC...BASED ON SNOWFALL AMOUNTS RECEIVED EARLY THIS MORNING WL UP
SNOW AMTS IN THE LAKE GEORGE SARATOGA REGION/ S VT. BAND OF HVY SN
HAS SHRUNK SOME AND EDGED NORTH.  BUT...A LOT OF UPSTREAM
PRECIPITATION ON RADAR.  SOUTH OF MAIN BAND LTL SHOWG ON RADAR TO S
BUT A LOT OF LGT RA AND DRZL NOTED.  ALSO WILL FINE TUNE SOME
TEMPERATURES.

AN EXTENDED WINTERY MESS FOR MUCH OF EASTERN NEW YORK AND
WESTERN NEW ENGLAND UNDERWAY.

COLD AIR SEEPED SOUTH DURING THE DAY THURSDAY SLOWLY DROPPING TEMPS
TO OR BELOW FREEZING ACROSS MUCH OF CWA.  COLD AIR CONTINUED TO
DEEPEN THURSDAY EVENING AND LOOKS LIKE IT WILL BE WELL ENTRENCHED
THROUGH MUCH OF AREA INTO SATURDAY MORNING.  INITIAL LOW PRESSURE
WAVES HAVE BROUGHT MODERATE PRECIP BAND FROM EXTRM SW ADIRONDACKS TO
SOUTHERN VERMONT.  SECOND STRONGER WAVE TO BRING ANOTHER SHOT OF
SIGNIFICANT PRECIPITATION LATER TODAY THROUGH SATURDAY MORNING.
WHILE EXACT PRECIPITATION TYPE IS STILL A QUESTION IT IS NOW CLEAR
FREEZING/FROZEN WILL DOMINATE EXCEPT IN EXTREME SOUTH.  INTERESTING
NOTE FWC/NGM TEMPERATURES SUPERIOR ON  TEMPERATURES DURING THE DAY
THURSDAY. ETA/MET AS WOULD BE EXPECTED TOO WARM.

SNOW LINE AT MIDNIGHT WAS A LITTLE SOUTH OF A WATERTOWN...GLENS
FALLS...KEENE LINE.  T-3 INCHES OF SNOW REPORTED THEN IN
NORTHERNMOST SARATOGA SOUTHERN WARREN COUNTY.  6 INCHES AT 1900 FEET
IN BENNINGTON COUNTY.  +SN AT KGFL SUGGESTS EVEN GREATER TOTALS.
ETA HOURLY SOUNDINGS INDICATE SNOW LINE WILL BE FURTHER SOUTH TODAY
THAN PREVIOUS FORECAST.  AT GLENS FALLS THEY SUPPORT MOSTLY SNOW
WITH SOME SLEET TODAY INTO THIS EVENING WITH SLEET AND THEN FREEZING
RAIN OVERNIGHT INTO SATURDAY.  AT KALB ETA SOUNDINGS SUPPORT A LONG
PERIODS OF SLEET AND FREEZING RAIN.  EVEN SOME MIX AT KPOU.  GFS
PARTIAL THICKNESSES SUPPORT TRENDS OF ETA.

FOR THIS FORECAST CYCLE WILL PLACE SNOW EMPHASIS A LITTLE FURTHER
SOUTH TODAY.  PRECIPITATION IN FAR S LIKELY TO QUITE FAIRLY SPOTTY.
ETA AT KALB RATHER LIGHT DURING DAY TODAY.  TONIGHT SNOW LINE
RETREATS QUICKLY NORTH WITH EMPHASIS ON PL/FZRA. SATURDAY MORNING A
GRADUAL TRANSITION TO LIQUID EXCEPT POSSIBLY FAR N.

HEADLINES...FIRST FLOOD WATCH.  RAINFALL IN SOUTH WILL BE FAIRLY
LIGHT THROUGH THIS EVENING. FOR MOHAWK MOST PRECIPITATION WILL BE
FREEZING OR FROZEN.  WOULD BE INCLINED TO NOT ISSUE A WATCH IF NONE
WERE OUT BUT GIVEN ITS OUT WILL PUSH BACK VALID TIME UNTIL
SATURDAY.  LITTLE FALLS (MOHAWK) AND GAYLORDSVILLE (HOUSATONIC)
WOULD GO OVER WITH LESS THAN AN INCH OF RAIN.

WILL EXTEND WINTER STORMS WARNINGS FURTHER SOUTH TO INCLUDE CAPITAL
DISTRICT...MOHAWK VALLEY...NORTHERN CATSKILLS AND BERKSHIRES.
ALREADY 1/4+ INCH  ICE ACCRETION.  ETA SUGGESTS PRECIPITATION MAY BE
RELATIVELY LIGHT TODAY...BUT MORE SLEET AND FREEZING RAIN TONIGHT
INTO SATURDAY MORNING.  A SLIGHT SHIFT SOUTHWARD OF MAIN
PRECIPITATION BAND WOULD PRODUCE HEAVIER PRECIP TODAY.  HEAVIER SNOW
ACCUMULATIONS FORECAST IN NORTH PORTION OF WARNING.

IMPACT OF SLEET/FZRA DIFFICULT TO PEG.  WHERE MORE SLEET/SNOW FALLS
RISK OF POWER OUTAGES LESS.  BERKSHIRE COUNTY A SPECIAL PROBLEM.
WILL GO WITH WARNING BUT EMPHASIZE NORTHERN PORTIONS.  TEMPS STILL
MILD IN SOUTHERN BERKSHIRE BUT AQW AT 1C WITH RA....GREAT BARRINGTON
37.  TEMPERATURES FORECAST TO DROP THROUGH DAY. QPF IN SOUTHERN HALF
OF COUNTY MIGHT BE LESS ALSO.
