SYNOPSIS
A COLD FRONT CROSSES LATE TONIGHT WITH HIGH PRESSURE BUILDING
IN FOR THE MIDDLE OF NEXT WEEK. ANOTHER STORM FEATURING MIXED
WINTRY PRECIPITATION IS LIKELY WEDNESDAY NIGHT INTO THURSDAY.
HIGH PRESSURE THEN BUILDS ACROSS NEW ENGLAND GOING INTO THE
WEEKEND.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
OUR MULTI-WAVED TROUGH IS FINALLY EXITING TO THE NE LATE
TONIGHT, BUT WE HAVE TWO MORE ROUNDS OF RAIN SHOWERS TO GO, ONE
WILL BE THIS EVENING AS THE FRONT APPROACHES, AND ANOTHER WILL
BE AFTER MIDNIGHT, MAINLY ALONG THE COAST, AS A WAVE MOVES ALONG
THE FRONT JUST BEFORE IT THE FROM EXITS THE CWA. SOME CONVECTIVE
CELLS POSSIBLE, AND MAYBE EVEN THUNDER OVER S NH, BUT STILL ONLY
A SMALL CHANCE. ANYPLACE THAT BROKE OUT OF THE FOG TODAY, WILL
SEE IT RETURN THIS EVENING AHEAD OF THE FRONT, BUT AWAY FROM THE
COAST IT SHOULD DIMINISH AFTER MID NIGHT, ONCE THE FRONT GOES
THROUGH. TEMPS THROUGH THE EVENING ARE LIKELY TO NOT MOVE MUCH
AT ALL, AND IF THEY DO, THEY ARE LIKELY TO GO UP, IF WE CAN GET
MIXING FROM THE INCREASED S FLOW. BEHIND THE FRONT THEY WILL
DROP, AND MORNING LOWS WILL RANGE FROM AROUND 30 IN THE MTNS TO
AROUND 40 IN THE S.
SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/
TUESDAY MAY START OFF CLOUDY, ESPECIALLY ALONG THE COAST AND IN
THE MTNS, BUT SHOULD SEE MAINLY SUNNY SKIES EVERYWHERE BY LATE
MORNING. NW WINDS BEHIND THE FRONT WILL PICK UP AS WELL AROUND
SUNRISE, WITH GUSTS IN THE 25-30 MPH RANGE THROUGH MUCH OF THE
DAY. THE CAA WILL LIKELY TAKE OVER IN THE AFTERNOON, AND HIGHS
RANGE FROM THE MID TO UPPER 30S IN THE MTNS TO AROUND 50 IN S NH
AND THE SW COAST OF ME.
WINDS WILL SUBSIDE TUE EVENING, ALTHOUGH WILL STILL SEE NW FLOW
AND COLD AIR CONVECTION CONTINUE. LOW WILL BE CHILLY COMPARED
TO RECENT NIGHTS, AND RANGE FROM THE MID TEENS IN THE MTNS TO
THE MID 20S IN THE S.
LONG TERM /WEDNESDAY THROUGH MONDAY/
AVIATION /20Z MONDAY THROUGH SATURDAY/
SHORT TERM...THE FOG HAS BEEN TOUGH TO BREAK TODAY, AND ANY
PLACE THAT MADE IT ABOVE IFR THIS AFTERNOON WILL LIKELY GO BACK
THIS EVENING, WITH SOME LIFR EXPECTED AS WELL. THE GOOD NEWS IS
THAT A COLD FRONT SHOULD IMPROVE CONDITIONS FROM NW-SE MIDNIGHT,
ALTHOUGH COASTAL TERMINAL MAY NOT IMPROVE UNTIL SUNRISE. VFR IS
THEN EXPECTED TUE AND TUE NIGHT. GUSTY NW WINDS TO AROUND 25 KT
ARE EXPECTED DURING THE DAY TUE, BUT THEY WILL SUBSIDE TUE
EVENING.
LONG TERM...
MARINE
SHORT TERM...SOUTHWESTERLY WINDS INCREASE AHEAD OF A COLD FRONT
TODAY, WITH LOW- END GALE FORCE GUSTS LIKELY ACROSS THE OUTER
WATERS THIS AFTERNOON AND EVENING. SCA CONDITIONS ARE EXPECTED
ELSEWHERE. THE COLD FRONT CROSSES THE WATERS LATE TONIGHT AND
TUESDAY MORNING. SCA CONDITIONS CONTINUE THROUGH TOMORROW, WITH
SEAS REMAINING ELEVATED THROUGH TOMORROW, AND NORTHWESTERLY WIND
GUSTS FRESHENING TO AROUND 25KT BY TOMORROW AFTERNOON.
LONG TERM...
I’VE CONVERTED THE GALES TO SCA BECAUSE WE ARE NOT SEEING THE
MIXING OF THE S WINDS DOWN TO THE SFC TODAY. THE WINDS ALOFT DO
PICKUP, AND THIS SHOULD PROVIDE BETTER MIXING THIS EVENING AND
OVERNIGHT. SEAS WILL COME UP AS WELL. WILL SEE A BREAK IN SCA
CONDS TOMORROW MORNING, BUT THEN NW FLOW PICKS UP TUE AFTERNOON
AND CONTINUES OVERNIGHT AT SCA LEVELS.
GYX WATCHES/WARNINGS/ADVISORIES
ME...NONE.
NH...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 6 AM EDT WEDNESDAY FOR ANZ150>152-
154.
