SYNOPSIS
HIGH PRESSURE BUILDS IN TONIGHT INTO SUNDAY MORNING. THE NEXT
DISTURBANCE CROSSES SUNDAY NIGHT BRINGING MAINLY SNOW SHOWERS TO
THE MOUNTAINS. HIGH PRESSURE RETURNS MONDAY INTO TUESDAY WHILE
AN AREA OF LOW PRESSURE DEVELOPS OVER THE GREAT LAKES. THIS LOW
PRESSURE SYSTEM WILL SLOWLY TRACK INTO SE CANADA LIFTING A WARM
FRONT INTO NEW ENGLAND TUESDAY NIGHT FOLLOWED BY THE ATTENDANT
COLD FRONT CROSSING THURSDAY. COOLER AND BREEZY CONDITIONS THEN
FOLLOW TO CLOSE OUT THE WEEK.
NEAR TERM /THROUGH TONIGHT/
SHORTWAVE WITHIN CYCLONIC FLOW MOVING INTO THE REGION WILL
CONTINUE SCATTERED SNOW SHOWERS ACROSS THE NORTHWESTERN
MOUNTAINS AND VALLEYS. SOME OF THESE ARE CAUSING BRIEF
VISIBILITY REDUCTIONS BELOW 2 MILES, BUT SHOULD TAPER OFF EARLY
THIS EVENING.
WINDS ARE ALSO PICKING UP WITH THE PASSAGE OF THIS WAVE, WITH
SOME GUSTS TO AROUND 25 MPH AT TIMES. ALSO EXPECT THESE GUSTS TO
TAPER OFF LATER, BUT IT SHOULD REMAIN BREEZY A LITTLE AFTER
SUNSET.
THIS BREEZE WILL BRING COOLER TEMPS BACK IN, BUT WILL PREVENT
EARLY DECOUPLING FOR RADIATIONAL COOLING TONIGHT. THINK NBM HAD
SOME GOOD LOW TEMPS ALL THINGS CONSIDERED, BUT TEMP TREND COOLER
WILL BE WEAK AT FIRST. BEST RAD COOLING MAY NOT HAPPEN UNTIL
CLOSER TO MIDNIGHT WITH CLEAR SKIES FOR ALL BUT THE MOUNTAINS.
ALL IN ALL, LOWS IN THE LOWER 20S WITH SOME TEENS SEEM MOST
LIKELY. HIGH CLOUDS BEGIN TO MOVE BACK INTO THE REGION BEFORE
SUNRISE.
SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/
MIDLEVEL JET MOVES OVER THE GREAT LAKES SUNDAY MORNING, WITH
WEAK LOW PRESSURE MOVING INTO NORTHERN NEW ENGLAND. IT WILL
MOSTLY BRING CLOUDINESS TO THE REGION AS THE PROSPECT OF NOTABLE
PRECIPITATION REMAINS LOW. WOULD EXPECT SOME SCATTERED SHOWERS
OR SNOW SHOWERS AS IT PASSES, BUT MOISTURE DEPTH IS ONLY NOTABLE
LATER IN THE EVENING AND FOR A SHORT DURATION.
DUE TO THE CLOUDS AND EARLY NW FLOW, HIGH TEMPS WILL BE A
COUPLE DEGREES COOLER THAN SATURDAY BUT WITH LIGHTER WINDS.
LINGERING PRECIPITATION TAPERS LAST IN THE MOUNTAINS OVERNIGHT,
AS CLOUDS KEEP OVERNIGHT LOWS A FEW DEGREES WARMER THAN TONIGHT.
LONG TERM /MONDAY THROUGH SATURDAY/
OVERVIEW: HIGH PRESSURE BUILDS IN MONDAY, BUT QUICKLY SHIFTS
OFFSHORE TUESDAY MORNING. A WARM FRONT WILL BRING INCREASING
CHANCES FOR PRECIPITATION LATE TUESDAY INTO WEDNESDAY WITH
TEMPERATURES RISING ABOVE NORMAL WEDNESDAY AFTERNOON. A COLD
FRONT CROSSES THURSDAY MORNING WITH COOLER, BREEZY, AND SHOWERY
CONDITIONS TO END THE WEEK.
IMPACTS: SOME SLICK TRAVEL WILL BE POSSIBLE IN THE MOUNTAINS TUESDAY
NIGHT INTO WEDNESDAY MORNING FROM LIGHT SNOW TRANSITIONING TO A
WINTRY MIX.
FORECAST DETAILS: SKIES TURN MOSTLY SUNNY ACROSS THE SOUTH
MONDAY WITH SNOW SHOWERS DIMINISHING IN THE MOUNTAINS. NW WINDS
IN THE WAKE OF A CLIPPER SYSTEM WILL GUST UP TO 25 MPH WITH
HIGHS RANGING FROM THE LOW 30S NORTH TO MID 40S SOUTH. HIGH
PRESSURE SLIDES ACROSS SOUTHERN NEW ENGLAND MONDAY NIGHT AND
TUESDAY MORNING FOR MOSTLY DRY WEATHER.
A WARM FRONT APPROACHES LATE TUESDAY WITH PRECIPITATION LIKELY
TUESDAY NIGHT. THERMAL PROFILES WILL SUPPORT SOME LIGHT SNOW TO
START ACROSS THE NORTH WITH RAIN BEING THE DOMINANT P-TYPE SOUTH
OF THE MOUNTAINS. THERE MAY BE A PERIOD OF A WINTRY MIX ACROSS
NORTHERN VALLEYS TUESDAY NIGHT THAT COULD BRING SLICK TRAVEL
INTO WEDNESDAY MORNING. TEMPERATURES ARE THEN FORECAST TO RISE
ABOVE FREEZING AFTER DAY BREAK WITH CHANCES OF RAIN CONTINUING
THROUGH THE DAY WEDNESDAY. HIGHS ON WEDNESDAY WILL RANGE FROM
THE 40S NORTH TO MID 50S SOUTH. A COLD FRONT CROSSES THURSDAY
MORNING ALLOWING FOR A CHANGE TO SNOW SHOWERS IN THE MOUNTAINS
WITH MOSTLY DRY A BREEZY CONDITIONS SOUTH OF THE MOUNTAINS.

THE WEEK WITH CONTINUED CHANCES FOR SNOW SHOWERS IN THE
MOUNTAINS.
