.SYNOPSIS...
A COLD FRONT WILL MOVE THROUGH THE REGION THIS MORNING FOLLOWED
BY A BLUSTERY NORTHWEST WIND. HIGH PRESSURE WILL BUILD TO THE
SOUTH OF THE AREA TONIGHT AND SATURDAY. A WARM FRONT APPROACHES
FROM THE SOUTHWEST MONDAY MORNING AND LIFTS NORTHEAST BY MONDAY
NIGHT. A COLD FRONT ATTEMPTS TO MOVE SOUTH MONDAY NIGHT/TUESDAY
MORNING. LOW PRESSURE PASSES BY WELL OFFSHORE WEDNESDAY AND
THANKSGIVING DAY. WEAK LOW PRESSURE PASSES TO THE NORTH FRIDAY
DRAGGING A COLD FRONT THROUGH THE REGION.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
900AM UPDATE.... FORECAST IS ON TRACK AS COLD AIR IS MOVING INTO
THE REGION. INCREASED POPS IN THE MOUNTAINS WHERE UPSLOPE SNOW
SHOWERS WILL CONTINUE THROUGH THE MORNING. MORNING KGYX SOUNDING
SHOWS GOOD POTENTIAL FOR WIND GUSTS TO MIX OUT TO THE 30MPH
RANGE... WITH HIGHEST GUSTS NEAR THE COAST.

PREV DISC...
AT 07Z...AN ARCTIC COLD FRONT WAS DRAPED ALONG THE SAINT LAWRENCE
VALLEY. THE FRONT WILL RACE SOUTHEAST AND OFFSHORE THIS MORNING.
ACROSS THE HIGHER TERRAIN WE`LL SEE CLOUDS AND A FEW SNOW SHOWERS
WITH ITS PASSAGE AND A FEW UPSLOPE CLOUDS AND SNOW SHOWERS IN ITS
WAKE. HIGHS TODAY WILL RANGE FROM THE TEENS IN THE MOUNTAINS TO
LOWER 30S AT THE COAST...BUT THE BLUSTERY NORTHWEST WIND WILL MAKE
IT FEEL A GOOD TEN TO FIFTEEN DEGREES COLDER THEN THAT.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
OUTSIDE OF A FEW CLOUDS ACROSS NORTHERN SECTIONS...IT`LL BE MAINLY
CLEAR AND COLD AS SURFACE HIGH PRESSURE BUILDS BY TO OUR SOUTH.
LOWS TONIGHT WILL BE IN THE SINGLE NUMBERS AND TEENS...WITH A FEW
20 DEGREE READINGS CONFINED TO THE IMMEDIATE COAST. ON
SATURDAY...A SOUTHWEST FLOW DEVELOPS AS THE SURFACE HIGH SHIFTS
OFFSHORE WITH CLOUDS GRADUALLY INCREASING IN DEVELOPING WARM AIR
ADVECTION PATTERN. EXPECT ANY LATE DAY SNOW SHOWERS TO BE CONFINED
TO NORTHERN SECTIONS. HIGHS SHOULD BE MAINLY IN THE 30S.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
SOMEWHAT QUIET BUT CHANGEABLE PERIOD OF WEATHER ON TAP FOR THE
EXTENDED INCLUDING THANKSGIVING. OVERALL UPPER LEVEL TROUGHING
REMAINS IN PLACE...BUT VARIOUS SHORT WAVES AND A PERIOD OF RIDGING
MAKE FOR A FEW DETAILS TO NOTE.

WE WILL SEE A NICE WARM UP SUNDAY THROUGH TUESDAY AS THIS
MERIDIONAL PATTERN BUCKLES AND RIDGING DEVELOPS OVER THE EASTERN
SEABOARD IN RESPONSE TO A DEEPENING TROUGH OVER THE CENTRAL CONUS.
PROMINENT SHORT WAVE ROTATING THROUGH THE TROUGH WILL PROMPT A
WARM FRONT TO LIFT THROUGH NEW ENGLAND MONDAY SPREADING MOSTLY
RAIN ACROSS THE AREA. SOME OF THE COOLER LOCATIONS EARLY SUNDAY
MORNING MAY HAVE A WINTRY MIX AT THE ONSET OF PRECIPITATION.
LIKEWISE...VERY EARLY MONDAY MORNING FREEZING RAIN MAY BE THE
PRECIPITATION TYPE FOR A FEW NORTHERN LOCATIONS AS SURFACE
TEMPERATURES DROP BELOW FREEZING.

PRECIPITATION BECOMES SHOWERY AS A COLD FRONT MOVES INTO THE
REGION...LIKELY CLEARING THE AREA MONDAY NIGHT/TUESDAY MORNING.
AS TEMPERATURES DROP LIGHT SNOW SHOWERS WILL DOMINATE IN UPSLOPE
AREAS. CLOUDS AND SHOWERS CLEAR OUT ACROSS THE COASTAL PLAIN AS
WINDS BECOME NW WEDNESDAY AND THANKSGIVING DAY. OCEAN LOW
PRESSURE PASSES WELL OUTSIDE THE BENCHMARK WEDNESDAY NIGHT AND
MOVES INTO THE MARITIMES THANKSGIVING DAY. THIS WILL HAVE SOME
IMPACT BY KEEPING A SLIGHT CHANCE OF RAIN JUST OFF THE COAST AND
TO STRENGTHEN DOWNSLOPE PROCESSES. THANKSGIVING DAY LOOKS COOL
WITH TEMPERATURES IN THE LOWER 30S NORTH TO UPPER 30S/LOWER 40S
SOUTH AND A SLIGHT CHANCE OF SHOWERS IN THE MOUNTAINS AND OVER THE
MIDCOAST.
