DISCUSSION
KEY MESSAGES 1...
AN UPPER LEVEL LOW OVER THE NORTHEAST COAST WILL ROTATE AND LIFT
NORTH AND OUT OF THE REGION LATER TODAY. NORTHWEST FLOW BEHIND THE
DEPARTING SYSTEM WILL BRING ONE FINAL COOL DAY BEFORE AN UPPER RIDGE
BEGINS BUILDING INTO THE AREA. WRAP AROUND MOISTURE ASSOCIATED
WITH THE LOW WILL CONTINUE TO PRODUCE ISOLATED TO SCATTERED AND
POCKETS OF DRIZZLE EARLY THIS MORNING, THOUGH MOST PRECIPITATION
WILL REMAIN LIGHT. SHOWERS WILL DISSIPATE AS THE MORNING PROGRESSES
AS DRIER AIR MOVES IN. OTHERWISE, SKIES WILL REMAIN MOSTLY CLOUDY
THROUGH THE MORNING BEFORE BECOMING PARTLY SUNNY THIS AFTERNOON
AS HIGH PRESSURE BUILDS NORTHWARD INTO THE REGION. TEMPERATURES
WILL CLIMB INTO THE LOW TO MID 60S THIS AFTERNOON.
THE OVERALL PATTERN SHIFTS THIS WEEKEND AS A RIDGE BUILDS INTO THE
REGION, BRINGING A MUCH WARMER AIR MASS. SOUTHWEST FLOW AND WARM AIR
ADVECTION WILL ALLOW TEMPERATURES TO REBOUND INTO THE MID 70S TO LOW
80S BY SATURDAY AND SUNDAY. DESPITE THE INFLUENCE OF HIGH
PRESSURE, MAINLY CLEAR SKIES ARE ONLY EXPECTED THROUGH SATURDAY
MORNING, AS A LOW PRESSURE SYSTEM APPROACHING FROM THE MIDWEST
INCREASES CLOUD COVER LATER IN THE DAY. A WARM FRONT IS EXPECTED
TO APPROACH THE REGION SATURDAY AFTERNOON INTO SATURDAY EVENING,
BRINGING THE CHANCE FOR ISOLATED SHOWERS AND THUNDERSTORMS.
KEY MESSAGE 2...
WARM AIR ADVECTION WILL CONTINUE INTO MIDWEEK, WITH TEMPERATURES
CLIMBING INTO THE 80S AND POSSIBLY REACHING 90 DEGREES IN A FEW
VALLEY LOCATIONS. ECMWF AND CONSALL GUIDANCE SUGGEST HIGHS
MAINLY IN THE LOW TO MID 80S WHILE THE NBM TRENDS WARMER WITH
TEMPERATURES IN THE MID TO UPPER 80S. TEMPERATURES FOR MONDAY
WERE ADJUSTED SLIGHTLY LOWER TO ACCOUNT FOR THE NBM RUNNING TOO
WARM DURING SEASONAL TRANSITION, KEEPING CENTRAL NY AND
NORTHEAST PA BELOW HEAT ADVISORY CRITERIA. WITH SOUTHWEST FLOW
IN PLACE, MOISTURE ADVECTION AHEAD OF AN APPROACHING COLD FRONT
WILL BRING CHANCES FOR SHOWERS TUESDAY AFTERNOON INTO TUESDAY
NIGHT. THE COLD FRONT IS CURRENTLY EXPECTED TO MOVE THROUGH THE
REGION AROUND WEDNESDAY, THOUGH SOME TIMING DIFFERENCES REMAIN
WITHIN THE ENSEMBLE GUIDANCE. THIS COULD BRING ADDITIONAL
SHOWERS AND POSSIBLY THUNDERSTORMS, ESPECIALLY IF THE FRONT
MOVES THROUGH DURING THE AFTERNOON OR EVENING HOURS.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
A BROKEN DECK OF MAINLY MVFR CEILINGS CONTINUES TO LINGER
AROUND MOST OF THE TERMINALS THIS AFTERNOON AS AN UPPER LEVEL
LOW PUSHES EASTWARD. HIGH PRESSURE BUILDING IN FROM THE WEST
WILL ALLOW CONDITIONS TO GRADUALLY IMPROVE OVER THE NEXT SEVERAL
HOURS AS THE CLOUDS SCATTER OUT AND VFR CONDITIONS RETURN FOR
THE EVENING. WEST TO NORTHWEST WINDS WILL BECOME LIGHT AND
VARIABLE TONIGHT.
VFR CONDITIONS ARE EXPECTED THROUGH THE REST OF THE TAF PERIOD
AT ALL TERMINALS. WINDS WILL BE BECOMING SOUTHWESTERLY LATER
TOMORROW MORNING WITH GUSTS OF 15-20 KNOTS EXPECTED INTO THE
EARLY AFTERNOON. LOCALLY STRONGER WIND GUSTS ARE POSSIBLE AFTER
18Z.
OUTLOOK:
SATURDAY AFTERNOON THROUGH MONDAY...MAINLY VFR; SMALL CHANCE
FOR AN ISOLATED SHOWER OR THUNDERSTORM LATE SATURDAY INTO
SUNDAY, WHICH MAY RESULT IN BRIEF RESTRICTIONS.
TUESDAY...MAINLY VFR, BUT AFTERNOON SCATTERED SHOWERS AND
THUNDERSTORMS MAY RESULT IN BRIEF RESTRICTIONS.
WEDNESDAY...SCATTERED SHOWERS AND THUNDERSTORMS AND ASSOCIATED
RESTRICTIONS POSSIBLE AS A FRONTAL BOUNDARY MOVES INTO THE AREA.
