DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
AFTER SOME EARLY MORNING LOW CLOUDS AND FOG, CONFIDENCE IS HIGH
THAT FAIR WEATHER WILL PREVAIL TODAY THROUGH AT LEAST
WEDNESDAY. BROAD HIGH PRESSURE OVER SOUTHERN CANADA WILL BE THE
SOURCE OF THIS FAIR WEATHER AS IT DRIFTS EAST THROUGH THE WEEK.
AS THE HIGH REMAINS CENTERED NORTH OF THE AREA, TEMPERATURES
WILL TREND COOLER THAN NORMAL FOR BOTH DAY TIME HIGHS AND
OVERNIGHT LOWS. THIS WILL TRANSLATE TO HIGHS IN THE LOW TO MID
60S AND LOWS IN THE 30S TO 40S. THERE WILL LIKELY BE FAVORABLE
RADIATIONAL COOLING CONDITIONS MOST NIGHTS AND IT IS LIKELY SOME
SPOTS SOUTH OF THE MOUNTAINS WILL SEE SOME FROST.
KEY MESSAGE 2 DESCRIPTION...
AT THE END OF THE WEEK, MODELS HAVE CONSISTENTLY SHOWN THE
POTENTIAL FOR A COASTAL LOW TO IMPACT THE REGION. A HIGH DEGREE
OF STORM TRACK UNCERTAINTY STILL REMAINS, BUT THE LOW COULD
ALLOW FOR SOME MUCH NEEDED RAINFALL OVER THE WEEKEND IF THE LOW
TAKES A MORE WESTERLY OR NORTHERLY TRACK. GUSTY WINDS AND HIGH
SURF COULD BE POSSIBLE AS WELL.
AVIATION /08Z MONDAY THROUGH FRIDAY/
THROUGH 06Z TUESDAY: MAINLY VFR OUTSIDE OF NIGHTTIME VALLEY
FOG. ANY LOW CLOUDS AND FOG EARLY THIS MORNING SHOULD LIFT WITH
INCREASING NORTH WINDS, LINGERING ACROSS THE MOUNTAINS AND CT
RIVER VALLEY. VALLEY FOG MAY RETURN AGAIN OVERNIGHT INTO
TUESDAY.
OUTLOOK:
TUESDAY-WEDNESDAY: MAINLY VFR WITH NO SIG WX.
THURSDAY-FRIDAY: MAINLY VFR OUTSIDE OF NIGHTTIME VALLEY FOG.
SOME INCREASE IN WINDS AND SHOWERS POSSIBLE LATE FRIDAY AND
FRIDAY NIGHT.
MARINE
HIGH PRESSURE WILL REMAIN CENTERED NORTH OF THE WATERS THROUGH
MID WEEK WHILE AN AREA OF LOW PRESSURE DEVELOPS OFFSHORE OF THE
MID ATLANTIC. WINDS AND SEAS LIKELY REMAIN BELOW SCA THRESHOLDS
INTO TUESDAY. A STRENGTHENING NE GRADIENT WILL BRING POTENTIAL
FOR PERIODS OF SCA CONDITIONS WEDNESDAY AND THURSDAY AND
POTENTIAL FOR GALES LATE IN THE WEEK DEPENDING ON THE TRACK OF
THE LOW PRESSURE SYSTEM. REGARDLESS OF TRACK, SEAS WILL LIKELY
BUILD IN EXCESS OF 5-7FT AROUND THURSDAY AND CONTINUE TO BUILD
