SHORT TERM...(TODAY-FRIDAY)

BREEZY AND SLIGHTLY COOLER/DRIER CONDITIONS ARE EXPECTED TODAY IN
THE WAKE OF A COLD FRONT THAT PASSED THROUGH EARLIER THIS MORNING.
THE LATEST MODEL GUIDANCE HAS INITIALIZED WELL WITH THE CURRENT
PATTERN AND INDICATES THE DEEP UPPER TROUGH IN PLACE OVER THE EAST
COAST QUICKLY LIFTING NORTHEAST AND AWAY FROM THE LOCAL AREA TODAY.
HIGH PRESSURE WILL BUILD EASTWARD OVER THE REGION WITH MAINLY DRY
AND BREEZY NORTHWEST LOW-LEVEL FLOW CONTINUING. DEWPOINTS HAVE
ALREADY DIPPED INTO THE MID 50S NEAR THE LAKE REGION AND ARE
EXPECTED TO DROP INTO THE 40S THROUGH THE AFTERNOON HOURS. THE
LATEST RUC GUIDANCE ACTUALLY INDICATES SLIGHTLY LOWER DEWPOINTS
THROUGH THIS TIME TODAY...WHICH CAN'T BE RULED OUT DUE TO THE
POTENTIAL FOR DRIER AIR MIXING DOWN. TEMPERATURES WILL START OFF IN
THE 60S THIS MORNING AND ARE ONLY EXPECTED TO REACH THE MID/UPPER
70S THROUGH THE AFTERNOON HOURS...WHICH WILL BE 10-15 DEG COOLER
THAN YESTERDAY AFTERNOON ALONG THE EAST COAST. LATER TONIGHT INTO
THURSDAY MORNING...OVERNIGHT LOWS ARE FORECAST TO DIP INTO THE LOWER
50S ACROSS THE NWRN INTERIOR AREAS TO THE LOWER 60S ALONG THE EAST
COAST. THE PRESSURE GRADIENT WILL GRADUALLY WEAKEN TONIGHT THROUGH
THURSDAY AS HIGH PRESSURE CONTINUES EASTWARD OUT INTO THE ATLANTIC
AND THE LOW-LEVEL FLOW VEERS BACK TO THE EAST. THE COMBINATION OF
ZONAL FLOW ALOFT AND ONSHORE LOW-LEVEL FLOW OFF THE ADJACENT
ATLANTIC WATERS WILL LEAD TO INCREASING LOW-LEVEL MOISTURE AND
TEMPERATURES THURSDAY THROUGH FRIDAY. TEMPERATURES ARE FORECAST TO
RETURN TO NORMAL THROUGH THIS SECOND HALF OF THE SHORT-TERM PERIOD.

LONG TERM...(FRIDAY NIGHT-EARLY NEXT WEEK)

THE LATEST EXTENDED MODEL GUIDANCE REMAINS IN DECENT AGREEMENT
THROUGH THE UPCOMING WEEKEND AND CONTINUES TO SHOW MOSTLY ZONAL
UPPER FLOW ACROSS THE REGION. THE LOW-LEVEL RIDGE AXIS IS FORECAST
TO REMAIN NORTH OF THE LOCAL AREA WITH LIGHT TO MODERATE EASTERLY
FLOW CONTINUING. TEMPERATURES WILL REMAIN AROUND NORMAL THROUGH THE
PERIOD WITH SLIGHTLY WARMER OVERNIGHT LOWS ALONG THE EAST COAST DUE
TO THE PERSISTENT ONSHORE FLOW. ANOTHER COLD FRONT ASSOCIATED WITH
AN UPPER TROUGH IS PROGGED TO PROGRESS EASTWARD INTO THE REGION AND
APPROACH THE STATE EARLY NEXT WEEK...WHICH COULD LEAD TO INCREASING
DEEP LAYER MOISTURE AND RAIN CHANCES.

MARINE...

FRESH TO STRONG NORTHWEST FLOW IN THE WAKE OF A COLD FRONT WILL
CONTINUE THROUGH THE MORNING HOURS TODAY...THEN BEGIN TO WEAKEN
TONIGHT THROUGH THE SECOND HALF OF THE WEEK AS HIGH PRESSURE BUILDS
EAST NORTH OF THE MARINE AREA. WINDS ARE FORECAST TO QUICKLY SHIFT
TO THE EAST LATER TONIGHT THROUGH THE UPCOMING WEEKEND WITH MOSTLY
DRY CONDITIONS EXPECTED.
