209 PM EST THU MAR 8 2007

...RECORD COLD TONIGHT WILL GIVE WAY TO A WARMING TREND BY WEEKEND...

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
UPDATE TO ADD WIND CHILL ADVISORY...SEE BELOW.

PREFRONTAL TROUGH HAS PUSHED THROUGH SOUTHERN NEW ENGLAND...
AND ARCTIC FRONT IS EDGING THROUGH SW NH AS OF 1 PM. FRONT WILL
CONTINUE TO PUSH S THROUGH AFTERNOON AND WILL INTRODUCE MUCH COLDER
AIR INTO REGION.

SATELLITE AND RADAR SHOW PLENTY OF CLOUD STREETS AND FLURRIES
THROUGHOUT REGION AS INSTABILITY INCREASES. MODELS SHOW STEEP LOW
LEVEL LAPSE RATES OF 9C/KM...AND AS FRONT DROPS S WE EXPECT TO SEE
ACTIVITY INCREASE THROUGH LATE AFTERNOON. WE STILL DO NOT THINK ANY
HEAVIER SNOW SHOWERS OR SQUALLS WILL BE TOO WIDESPREAD...SO IT WILL
BE MORE OF A LOCALIZED OCCURRENCE AT BEST. ONE RECENTLY MOVED THROUGH
MANCHESTER AND DROPPED VISIBILITY TO 1 1/2SM. 12Z NAM AND 10KM BOX
WRF SUGGEST COASTAL PLAIN FROM CAPE ANN INTO BOSTON AND CAPE COD WILL
BE FOCUS FOR ANY SIGNIFICANT ACTIVITY...PRIMARILY BETWEEN 1 AND 5
PM...BUT RIGHT NOW WE ONLY EXPECT A DUSTING OF ACCUMULATION AT BEST.

CLEARING SETS IN THIS EVENING AS DRYING AND SUBSIDENCE INCREASES OVER
REGION...WITH CLEAR SKIES PERSISTING INTO FRI AS HIGH PRESSURE BUILDS
OVERHEAD.

GUSTY WINDS WILL DIMINISH QUICKLY AS WELL TONIGHT...SETTING STAGE FOR
IDEAL RADIATIONAL COOLING ESPECIALLY AWAY FROM COAST. ALL MOS
GUIDANCE /NGM...ETA AND GFS/ APPEARS TO BE TOO WARM WHICH IS A
TYPICAL BIAS IN COLD OUTBREAKS. WE WILL CONTINUE TO GO BELOW MOS AND
SIDE CLOSER TO NAM 2M TEMPERATURES WHICH BRINGS LOWS BELOW ZERO
ACROSS FAR INTERIOR...WELL DOWN INTO SINGLE NUMBERS FOR HARTFORD...
PROVIDENCE AND BOSTON...AND CLOSE TO 10F ON CAPE COD AND ISLANDS.

ALTHOUGH WINDS WILL DIMINISH TONIGHT...WIND CHILLS WILL STILL MANAGE
TO FALL TO 15 BELOW ACROSS SOME OF HIGHER ELEVATIONS...PRIMARILY ON
EAST SLOPES OF BERKSHIRES AND IN WORCESTER COUNTY...WHERE WE WILL
ISSUE A WIND CHILL ADVISORY IN COLLABORATION WITH WFO ALBANY. CRITERIA
IS LOWER IN SW NH /-20F/ SO WE DO NOT NEED AN ADVISORY THERE.
ELSEWHERE WIND CHILLS WILL GET DOWN TO 10 BELOW ZERO TONIGHT.

OTHERWISE...WARMING TREND GETS UNDERWAY FRI AS HIGH PRESSURE MOVES
OFFSHORE AND FLOW TURNS SW. WARM ADVECTION WILL BRING GRADUAL
INCREASE IN HIGH CLOUDS FRI AFTERNOON AND FRI NIGHT.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
COMING SOON.

&&

.AVIATION /19Z-18Z/...
ARCTIC FRONT IS PUSHING THROUGH SW NH...WHILE PREFRONTAL TROUGH HAS
ALREADY BROUGHT WINDS TO NW AS WELL AS AN INCREASE IN GUSTS. EXPECT
N/NW WINDS TO PREVAIL THROUGH THIS EVENING WITH STRONGEST GUSTS UNTIL
23Z WITH PASSAGE OF ARCTIC FRONT. SUSTAINED WINDS MAY REACH 25KT ON
COASTAL PLAIN WITH 35KT GUSTS...WHILE INLAND WINDS WILL BE A BIT
LOWER WITH SUSTAINED 15-20KT AND GUSTS TO 30KT. WIND WILL CONTINUE TO
PRODUCE MECHANICAL TURBULENCE AND ASSOCIATED LLWS. WE HAVE SEEN
SEVERAL PIREPS MENTIONING LLWS SO FAR THIS AFTERNOON.

WINDS WILL DROP OFF QUICKLY TONIGHT...AROUND 00Z INLAND AND 06Z ALONG
COAST...AS HIGH PRESSURE BUILDS OVERHEAD. LIGHT NW OR LIGHT/VARIABLE
WINDS BECOME W/SW 10KT FRI.

SATELLITE AND RADAR SHOW PLENTY OF CLOUD STREETS OVER SOUTHERN NEW
ENGLAND WITH FLURRIES AND ISOLATED HEAVIER SNOW SHOWERS. THESE WILL
PERSIST THROUGH LATE AFTERNOON BUT CONDITIONS SHOULD STAY VFR. A FEW
LOCATIONS COULD DROP TO IFR WITH 2SM -SHSN AND CEILINGS BKN015...BUT
THAT WILL BE BRIEF. MOST LIKELY LOCATIONS INCLUDE INTERIOR HIGHER
TERRAIN AND PERHAPS COASTAL PLAIN...WHERE LOW LEVEL CONVERGENCE IS
MAXIMIZED.

CLEARING WILL SET IN THIS EVENING WITH CLEAR SKIES LASTING INTO FRI.

OUTLOOK 18Z FRI TO 12Z SAT...
VFR. GRADUAL INCREASE IN HIGH CLOUDS WITH CEILINGS AOA 15KFT. SW
WINDS INCREASE TO 15-20KT ALONG COAST AND 10KT OR LESS INLAND.

LIKELY UNTIL THIS EVENING. ELSEWHERE...GUSTS SHOULD HOLD BETWEEN 25
AND 30KT.
