KEY MESSAGE 1
MAINLY DRY AND COMFORTABLE CONDITIONS PERSIST TODAY.
SURFACE HIGH PRESSURE DROPS INTO THE UPPER GREAT LAKES, WITH A
LIGHT NORTHERLY FLOW LOCALLY AWAY FROM THE COASTAL SEA BREEZES.
A SPOTTY, ISOLATED SHOWER IS POSSIBLE THIS AFTERNOON, ESPECIALLY
INLAND OFF THE HIGHER TERRAIN AND PERHAPS ALONG SEA BREEZE
FRONTS, INVOF A WEAK SFC TROUGH AND ONE LAST WEAK SHORTWAVE
ALOFT PASSING THROUGH THE LONGER WAVE UPPER TROUGH OVER THE
AREA. TEMPERATURES ARE NEAR CLIMO NORMS IN THE 70S.
KEY MESSAGE 2
GUIDANCE CONTINUES TO ADVERTISE EAST COAST TROUGHING SLIDING
AWAY ON WEDNESDAY, WITH RISING HEIGHTS AND ZONAL FLOW ALOFT
AROUND THE NORTHERN PERIPHERY OF AN AMPLIFYING RIDGE FOR THU
THRU SAT TIMEFRAME. AT THE SURFACE, HIGH PRESSURE OVER THE GREAT
LAKES AND MIDWEST TO START WILL SINK TO THE SOUTH AND SET UP OFF
THE SE US COAST BY FRI, WITH DEEP LAYER W-SW FLOW AND WAA.
TEMPS IN AREAS FROM NYC WEST SHOULD GET BACK INTO THE LOWER 80S
ON WED, WITH MORE WIDESPREAD MID TO UPPER 80S ON THU, AND
AROUND 90 FOR THE URBAN CORRIDOR OF NE NJ.
TEMPS LIKELY REACH 90-95 ON FRI/SAT FOR NYC/NJ METRO, NEARBY
SUBURBS AND IN PARTS OF THE LOWER HUDSON VALLEY. TEMPS COULD
GET CLOSE TO DAILY RECORD HIGHS ON THU AT BRIDGEPORT AND AT MOST
CLIMATE SITES EXCEPT FOR CENTRAL PARK ON FRI, WITH RECORD HIGH
MINS POSSIBLE ON SAT. NBM DEWPOINTS ARE CURRENTLY PROGGED IN
THE 50S, WHICH WOULD KEEP HEAT INDEX VALUES AT OR JUST BELOW
TEMPS.
SLIGHTLY WARMER TEMPS AND HIGHER DEWPOINTS THAN FORECAST COULD
LEAD HEAT INDEX VALUES APPROACHING 95 BOTH FRI/SAT FOR THE URBAN
CORRIDOR OF NE NJ AND IN PARTS OF NYC WITH LESS AFTERNOON SEA
BREEZE INFLUENCE (MAINLY STATEN ISLAND/MANHATTAN). WPC DAY 3-7
PROBABILITIES (BASED ON GEFS, ECES, AND NAEFS) FOR >95F HEAT
INDEX VALUES REFLECT THIS, CONTINUING TO RUN IN THE 10-40%
RANGE.
KEY MESSAGE 3
GENERAL AGREEMENT ON A NORTHERN STREAM TROUGH
AMPLIFYING AS IT MOVES THROUGH SE CANADA SAT INTO SUN, WITH A
BACK DOOR COLD FRONT PUSHING THROUGH THE REGION LATE SAT INTO
SAT NIGHT. THIS WOULD BRING AN END TO THE HEAT HEADING INTO
SUNDAY, AND ALONG WITH ANOTHER UPPER LEVEL TROUGH APPROACHING
FROM THE GREAT LAKES WOULD BRING INCREASING CHANCES FOR SHOWERS
AND POSSIBLE TSTMS FROM LATE DAY SAT INTO EARLY NEXT WEEK.
