AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
256 PM EST SUN FEB 18 2007

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
BACK EDGE OF SNOW SHOWERS EXITING CAPE COD AND NANTUCKET AT THIS
TIME AND SHOULD BE GONE BY EVENING. NOT MUCH ACCUMULATION REPORTED
THERE SO FAR AND THAT SEEMS ABOUT RIGHT ACCORDING TO AREA WEBCAMS.
WE DID RECEIVE A REPORT FROM NANTUCKET OF ONE INCH EARLIER.

OTHERWISE...LOTS OF FLURRIES AROUND SOUTHERN NEW ENGLAND ACCORDING
TO KBOX RADAR /IN CLEAR AIR MODE/ AND WE HAVE HAD SOME REPORTS OF
BRIEF SNOW SHOWERS ACROSS HIGHER ELEVATIONS. THIS ACTIVITY CERTAINLY
HAS A CONVECTIVE LOOK TO IT...ESPECIALLY ON SATELLITE...AND WE
EXPECT THIS TO DIMINISH LATE THIS AFTERNOON WITH LOSS OF DAYTIME
HEATING.

UPPER TROUGH WILL MOVE THROUGH REGION EARLY TONIGHT ALONG WITH
ASSOCIATED COLD FRONT. STRONG COLD ADVECTION GETS UNDERWAY LATER
THIS EVENING AND PRESENTS SEVERAL CONCERNS INCLUDING STRONG
WINDS...BITTERLY COLD WIND CHILLS...AND FREEZING SPRAY ON COASTAL
WATERS. SEE MARINE SECTION BELOW FOR DETAILS ON MARINE HAZARDS.

WE WILL ISSUE A WIND ADVISORY FOR CAPE COD AND ISLANDS FROM MIDNIGHT
TONIGHT UNTIL 3 PM MON FOR SUSTAINED 25 TO 35 MPH NW WINDS WITH
GUSTS AS HIGH AS 45 MPH. MIXING LAYER DEEPENS DRAMATICALLY LATER
TONIGHT AS COLD ADVECTION GETS UNDERWAY...BUT STRONGEST WINDS SEEM
TO BE CONFINED TO SE NEW ENGLAND SO WE WILL NOT INCLUDE METRO BOSTON
OR INTERIOR HIGH TERRAIN AT THIS TIME. WIND FIELD APPEARS TO BE
STRONGEST MON MORNING WHEN WE HAVE BETTER CHANCE OF 45 MPH GUSTS IN
ADVISORY AREA. SOUNDINGS SHOW ENOUGH OF AN INVERSION PRESENT
ELSEWHERE TO PREVENT THESE GUSTS FROM MIXING DOWN...ALTHOUGH IT WILL
BE CLOSE AROUND CAPE ANN.

GUSTY WINDS AND SHARPLY COLDER AIR WILL ALSO BRING WIND CHILLS DOWN
INTO ADVISORY RANGE /-15F/ ACROSS PARTS OF WESTERN AND CENTRAL MA...
NAMELY E SLOPES OF BERKSHIRES AND IN WORCESTER COUNTY. THESE MORE
ELEVATED SITES WILL MAINTAIN GUSTY WINDS THROUGH NIGHT...WHILE
ADJACENT ZONES WHICH FEATURE SOMEWHAT LOWER TERRAIN WILL BE CUT OFF
TO SOME DEGREE BY NOCTURNAL INVERSION. WE SHOULD ALSO NOTE THAT
ALTHOUGH WIND CHILLS WILL REACH SIMILAR VALUES ACROSS SW NH...OUR
THRESHOLD FOR ADVISORIES IS -20F THERE...SO WE DO NOT NEED TO
INCLUDE CHESHIRE OR HILLSBOROUGH COUNTIES AT THIS TIME.

OTHERWISE SKIES SHOULD CLEAR OUT OVERNIGHT AS SUBSIDENCE INCREASES
AND CROSS SECTIONS SHOW DRYING THROUGH COLUMN. DESPITE EXTREME
INSTABILITY ON FORECAST SOUNDINGS NEAR CAPE COD...LOW LEVEL FLOW IS
FROM NW AND TOO STRONG TO SUPPORT MENTION OF SNOW SHOWERS THERE. ALL
OF ACTIVITY WILL BE FOCUSED WELL OFFSHORE.

SURFACE RIDGE WORKS INTO NEW ENGLAND MON AFTERNOON...WHICH WILL
CAUSE WINDS TO DIMINISH. AT SAME TIME...NEXT CLIPPER SYSTEM IS
ALREADY HEADING ACROSS GREAT LAKES AND WILL BEGIN TO SEND INCREASING
MID AND HIGH CLOUDINESS OUR WAY. WE THINK SKIES WILL CLOUD OVER
AGAIN MON NIGHT...BUT ANY PRECIPITATION WILL HOLD OFF INTO TUE
MORNING SINCE CROSS SECTIONS INDICATE LIFT IS RATHER WEAK AND
CENTERED AT MID LEVELS. WE MAY SEE SOME FLURRIES ACROSS INTERIOR BUT
WE WILL LEAVE THAT OUT FOR NOW.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
COMING SOON.

&&

.AVIATION /20Z-18Z/...
MVFR NEAR CAPE COD AND ISLANDS WILL IMPROVE TO VFR BY EARLY THIS
EVENING AS BACK EDGE OF SNOW AND LOWER CLOUDS HEADS OFFSHORE.
OTHERWISE VFR THROUGH 18Z MON AS CLEARING SETS IN TONIGHT...ASIDE
FROM LOCAL MVFR INTO THIS EVENING ACROSS INTERIOR WHERE FLURRIES
PERSIST.

MAIN CONCERN FOR TONIGHT INTO MON IS STRONG WIND AND POTENTIAL FOR
MECHANICAL TURBULENCE. STRONGEST WINDS WILL AFFECT COASTAL TAF SITES
FROM 05Z TO 19Z MON...ESPECIALLY CAPE COD AND ISLANDS WHERE
SUSTAINED 25-30KT WINDS AND GUSTS TO 40 MPH ARE MOST LIKELY TO
OCCUR. REMAINING TAF SITES WILL HAVE SUSTAINED 20-25KT AND GUSTS TO
35KT AT MOST... ESPECIALLY FROM 12Z-19Z MON.

OUTLOOK BEYOND 18Z MON...
WINDS WILL DIMINISH RAPIDLY MON AFTERNOON AND EVENING AS FLOW
BECOMES W/SW.

INCREASING MID AND HIGH CLOUDS EXPECTED LATE MON AND MON NIGHT WITH
CEILINGS LOWERING TO 10KFT...AS CLIPPER SYSTEM APPROACHES FROM GREAT
LAKES. MVFR POSSIBLE ACROSS SW NH AND NW MA 06Z-12Z TUE WHERE
CEILINGS MAY LOWER JUST BELOW 3KFT...BUT CONFIDENCE IS NOT HIGH AND
CEILINGS 4-6KFT ARE MORE LIKELY AT THIS TIME. WE DO NOT THINK THERE
WILL BE ANYTHING MORE THAN FLURRIES AT THIS POINT WITH NO
RESTRICTION TO VISIBILITY...SINCE LIFT IS WEAK AND CENTERED AT MID
LEVELS.

&&

.MARINE...
GALE WARNINGS REMAIN POSTED FOR ALL WATERS BEGINNING AT MIDNIGHT.
ALTHOUGH NW WINDS WILL BEGIN TO INCREASE SHARPLY THIS
EVENING...ONSET OF GALE FORCE WINDS IS NOT EXPECTED UNTIL
MIDNIGHT...WHEN COLDER AIR BEGINS TO SURGE INTO REGION. STRONGEST
GUSTS WILL OCCUR OFFSHORE AND MAINLY FROM LATE TONIGHT THROUGH MON
MORNING...BEFORE WINDS BEGIN TO SUBSIDE.

IN ADDITION...HEAVY FREEZING SPRAY WARNINGS ARE BEING ISSUED FOR ALL
WATERS EXCEPT BOSTON HARBOR AND NARRAGANSETT BAY. VERY COLD AIR
POURING OVER RELATIVELY MILDER OCEAN WATER WITH GALE FORCE WINDS AND
ROUGH SEAS WILL PRODUCE HEAVY FREEZING SPRAY FROM LATE TONIGHT
THROUGH MOST OF MON. WORST CONDITIONS SHOULD OCCUR MON MORNING NEAR
SHORE...WHEN AIR TEMPERATURES WILL BE IN TEENS.

MARINERS HEADING OFFSHORE SHOULD ALSO BE AWARE OF SNOW SHOWERS AND
LOCALIZED SQUALLS LATE TONIGHT INTO MON. SOUNDINGS INDICATE EXTREME
INSTABILITY WITH WELL ALIGNED NW FLOW OVER OCEAN...PROBABLY TOO
STRONG TO FOCUS ACTIVITY NEAR SHORE.

LONG TERM COMING SOON.
