SYNOPSIS
A PROLONGED PERIOD OF DRY WEATHER IS ON TAP THROUGH THE START OF
NEXT WEEKEND, AS A BROAD AREA OF HIGH PRESSURE CENTERED OVER THE
UPPER MIDWEST WILL SETTLE EAST-SOUTHEAST ACROSS THE GREAT LAKES AND
INTO THE NORTHEAST. A GRADUAL DAY TO DAY WARMING TREND WILL
SUPPORT ABOVE AVERAGE TEMPERATURES TO RETURN BY SUNDAY AND LAST
INTO THE START OF THE NEW WORK WEEK.
NEAR TERM /THROUGH SATURDAY NIGHT/
CLEAR SKIES, LIGHT WINDS, AND A DRY AIRMASS IN PLACE WILL SUPPORT
EFFICIENT RADIATIONAL COOLING TONIGHT SUPPORTING TEMPERATURES TO
DROP LIKE A ROCK WITH LOWS BOTTOMING OUT IN THE LOW TO MID 40S
ACROSS THE HIGHER TERRAIN OF THE SOUTHERN TIER AND EASTERN LAKE
ONTARIO REGION, AND UPPER 40S TO LOW 50S ACROSS THE LAKE PLAINS.
GIVEN THE DROP IN TEMPERATURES, FOG WILL LIKELY DEVELOP ACROSS THE
RIVER VALLEYS TONIGHT, ESPECIALLY ACROSS THE SOUTHERN TIER.
SURFACE HIGH PRESSURE WILL CENTER ITSELF ACROSS THE LOWER GREAT
LAKES REGION SATURDAY AND SATURDAY NIGHT, SUPPORTING ANOTHER DRY DAY
AND NIGHT. THE ONLY DIFFERENCE BETWEEN TODAY AND SATURDAY, IS
SATURDAY WILL BE SLIGHTLY WARMER WITH HIGHS NEAR NORMAL FOR THE
START OF AUGUST.
SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/
DRY WEATHER CONTINUES THROUGH THE END OF THE WEEKEND AND INTO THE
START OF NEXT WEEK AS BROAD SURFACE HIGH PRESSURE DRIFTS FROM FROM
THE THE GREAT LAKES REGION SUNDAY AND INTO NEW ENGLAND MONDAY. IN
ADDITION TO THE DRY WEATHER, THE GRADUAL DAY TO DAY WARMING TREND
WILL CONTINUE, FEATURING ABOVE NORMAL HIGHS WELL INTO THE 80S.
LONG TERM /TUESDAY THROUGH FRIDAY/
SURFACE HIGH PRESSURE WILL CONTINUE TO DRIFT INTO NEW ENGLAND
THROUGH THE MIDDLE OF NEXT WEEK, BEFORE EXITING INTO THE CANADIAN
MARITIMES LATE IN THE WEEK. AS A RESULT, ASSOCIATED SUBSIDENCE AND
DRY AIR WILL KEEP THE AREA DRY AND MAINLY CLEAR TO PARTLY CLOUDY
THROUGH AT LEAST THE MIDDLE OF THE WEEK. BY LATE IN THE WEEK,
SOUTHERLY FLOW AROUND THE DEPARTING HIGH AND ASSOCIATED GRADUAL
INCREASE IN LOW LEVEL MOISTURE MAY ALLOW FOR A FEW ISOLATED SHOWERS
AND THUNDERSTORMS WITH DAYTIME HEATING, BUT COVERAGE OF THESE WILL
BE SPARSE, IF THEY DEVELOP AT ALL.
OTHERWISE, THE DAY TO DAY WARMING TREND WILL CONTINUE TUESDAY
THROUGH FRIDAY WITH HIGHS RANGING IN THE 80S EACH DAY.

ACROSS THE SOUTHERN TIER TONIGHT GIVEN THE CLEAR SKIES, CALM WINDS
AND DRY AIRMASS OVERHEAD PROMOTING EFFICIENT RADIATIONAL COOLING.
