...SNOW ADVISORY REMAINS IN EFFECT FROM 8 PM THIS EVENING TO 4 AM
EDT SUNDAY...
SNOWFALL TOTALS OF 2 TO 5 INCHES ARE EXPECTED TONIGHT...WITH AS MUCH
AS 6 INCHES POSSIBLE ABOVE 1000 FEET.
LIGHT RAIN WILL BEGIN FROM THE BERKSHIRES TO THE CONNECTICUT VALLEY
AROUND 7 PM AND WILL REACH HILLSBOROUGH AND WORCESTER COUNTIES
AROUND 8 PM. RAIN WILL CHANGE TO SNOW BY 9 OR 10 PM AS COLDER AIR
WORKS INTO THE REGION...AND WILL FALL HEAVILY AT TIMES FOR A FEW
HOURS AROUND MIDNIGHT. SNOW WILL END BETWEEN 2 AND 4 AM SUNDAY.
THE SNOW WILL LIKELY BE WET AND WILL EASILY CAKE ONTO TREES AND
POWER LINES. THIS MAY RESULT IN SOME BROKEN TREE BRANCHES AND
PERHAPS ISOLATED POWER OUTAGES.
AT LOWER ELEVATIONS...SUCH AS THE CONNECTICUT RIVER VALLEY...RAIN OR
A MIX OF RAIN AND SNOW WILL LAST FOR A LONGER PERIOD OF TIME. THIS
WILL RESULT IN LOWER SNOWFALL TOTALS OF 1 TO 3 INCHES.
A SNOW ADVISORY MEANS THAT SNOW WILL CAUSE PRIMARILY TRAVEL
DIFFICULTIES. BE PREPARED FOR SNOW COVERED ROADS AND LIMITED
VISIBILITIES...ESPECIALLY IN THE HIGHER ELEVATIONS...AND USE CAUTION
WHILE DRIVING.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE TAUNTON MA
450 PM EDT SAT MAR 24 2007
...STILL EXPECTING A 2 TO 5 INCH SNOWFALL ACROSS INTERIOR TONIGHT
WITH GREATEST AMOUNTS IN HIGHER ELEVATIONS...
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
CLOUD SHIELD CONTINUES TO MAKE STEADY EASTWARD PROGRESS AND WILL
OVERSPREAD SOUTHERN NEW ENGLAND BY EARLY EVENING. RADAR MOSAIC HAS
LEADING EDGE OF SHOWERS INTO NORTHERN NY AND EVEN ADJACENT PARTS OF
NORTHERN NEW ENGLAND...BUT MOST OF THIS IS ALOFT. RAIN IS REACHING
GROUND FARTHER W NEAR WATERTOWN AND SYRACUSE.
WE ARE CONTINUING SNOW ADVISORY FOR TONIGHT...BUT WE HAVE NUDGED
TOTALS UP SLIGHTLY OVER INTERIOR NE MA WHICH MEANS WE WILL ADD
CENTRAL MIDDLESEX COUNTY MA TO ADVISORY AT THIS TIME.
12Z NAM/GFS ARE IN GENERAL AGREEMENT IN HANDLING OF POTENT SHORT
WAVE AND ASSOCIATED SURFACE LOW DIVING SE FROM GREAT LAKES TONIGHT.
WE ARE LEANING MORE TOWARD NAM FOR DETAILS GIVEN ITS BETTER
RESOLUTION SINCE ELEVATION WILL PLAY A LARGE ROLE IN RAIN VS SNOW AS
WELL AS SNOWFALL TOTALS.
WE DO THINK NAM IS A BIT OVERDONE WITH ITS QPF OF 0.50 TO 0.75 INCH
ACROSS MUCH OF NORTHERN MA AND SW NH...ESPECIALLY WHEN COMPARED WITH
09Z SREFS WHICH ONLY SUPPORT 0.25 TO 0.50 INCH. HOWEVER THEY DO
AGREE THAT AXIS OF MAX QPF WILL BE ACROSS OUR NORTHERN ZONES...WITH
LESSER AMOUNTS OF 0.10 TO 0.25 INCH S OF MASS PIKE.
WE HAVE WARMED UP NICELY THIS AFTERNOON WITH ALL LOCATIONS WELL UP
INTO THE 40S AND LOWER 50S. IT IS THIS LOW LEVEL WARMING THAT WILL
BE KEY PLAYER IN HOW FAST WE SEE A CHANGEOVER FROM RAIN TO
SNOW...SINCE ALOFT IT IS STILL FAIRLY COLD AND WILL EASILY SUPPORT
SNOW AT ONSET. THIS IS A TYPICAL SPRING SNOWFALL EVENT WHERE HIGHER
ELEVATIONS ARE FAVORED...BUT SINCE SNOW WILL BE FALLING AT NIGHT WE
STAND TO SEE SOME ACCUMULATION AT LOWER ELEVATIONS AS WELL.
IN ORDER TO SEE MORE WIDESPREAD ADVISORY TOTALS...WE WOULD LIKE TO
SEE STRONGER LIFT ARRIVING AFTER MIDNIGHT...BUT SINCE IT IS COMING
IN DURING FIRST PART OF NIGHT...THAT SHOULD LIMIT EXTENT OF 2 TO 4
INCH TOTALS.
AS A RESULT...WE EXPECT LIGHT RAIN TO MOVE INTO SOUTHERN NEW ENGLAND
THIS EVENING...POSSIBLY MORE OF A RAIN/SNOW MIX AT HIGHER
ELEVATIONS... BEFORE CHANGING TO SNOW WITHIN A FEW HOURS OF ONSET.
IN ADDITION TO WET BULB COOLING...WE ALSO HAVE STRONG LIFT ENTERING
PICTURE AS A RESULT OF APPROACHING MID LEVEL SHORT WAVE...WHICH WILL
ALSO ACT TO COOL DOWN COLUMN FAIRLY QUICKLY. THIS CHANGEOVER WILL
TAKE PLACE BY 9 OR 10 PM ACROSS SW NH AND WESTERN/CENTRAL MA...BUT
PROBABLY NOT UNTIL 11 PM OR MIDNIGHT FARTHER S AND E INTO NORTHERN
CT...NORTHERN RI AND EASTERN MA...AND MORE LIKE 1 TO 2 AM NEAR S
COAST.
ALTHOUGH THIS SYSTEM IS PROGRESSIVE AND WILL EXIT REGION QUICKLY...
THERE WILL BE A 3 TO 4 HOUR PERIOD WHERE EVERYTHING COMES TOGETHER
TO PRODUCE DECENT SNOWFALL RATES...ESPECIALLY AT HIGHER ELEVATIONS
WHERE SNOW WILL BE MORE PROLONGED AND OVER OUR NORTHERN ZONES WHERE
CROSS SECTIONS INDICATE MAX SNOW GROWTH ZONE WILL BE. WHILE WE DO
NOT SEE SNOWFALL TOTALS IN EXCESS OF 6 INCHES IN OUR HIGHER
ELEVATION SITES...WE SHOULD BE ABLE TO GET WIDESPREAD 3 TO 5 INCH
TOTALS FROM MONADNOCKS TO E SLOPES OF BERKSHIRES AND WORCESTER HILLS
WITH 2 TO 4 INCHES ELSEWHERE ACROSS INTERIOR.
FARTHER S INTO NORTHERN CT...NORTHERN RI AND INTERIOR EASTERN MA...
WE THINK INITIAL LOW LEVEL WARMING WILL PLAY MORE OF A ROLE AND
LIMIT SNOWFALL ACCUMULATIONS TO 1 TO 3 INCHES...MAINLY ON
GRASS...SINCE RAIN/SNOW MIX SHOULD LAST A BIT LONGER AND BEST LIFT
IS CENTERED IN WARMER AIR. SOME OF HIGHER ELEVATIONS OF
HARTFORD...TOLLAND...WINDHAM AND PROVIDENCE COUNTIES COULD SEE AS
MUCH AS 3 TO 4 INCHES LOCALLY...BUT WE DO NOT THINK THESE TOTALS
WILL BE WIDESPREAD ENOUGH TO JUSTIFY ADVISORIES AT THIS TIME.
SYSTEM WILL ALREADY BE OFFSHORE SUN MORNING...SO SNOW SHOULD BE OVER
4 TO 6 AM SUN. LOW LEVEL MOISTURE WILL HANG ON INTO MORNING PER
CROSS SECTIONS...BEFORE DRYING SETS IN DURING MIDDAY AND AFTERNOON
AND ALLOWS FOR SKIES TO CLEAR.
TEMPERATURES SHOULD RECOVER NICELY SUN AFTERNOON...WELL INTO 40S IF
NOT 50F AT A FEW SPOTS S OF MASS PIKE.
WEAK HIGH PRESSURE BUILDS INTO REGION SUN NIGHT WITH ONLY PATCHY
HIGH CLOUDS EXPECTED.
