OVERVIEW...
HIGH PRESSURE REMAINS IN PLACE ACROSS NEW ENGLAND THROUGH THE
END OF THE WEEK AND INTO THE WEEKEND. LOW PRESSURE STALLS SOUTH
OF NEW ENGLAND LATE THIS WEEK, AND SLOWLY MOVES NORTHWARD
THROUGH THE WEEKEND. IMPACTS FROM THIS SYSTEM ARE POSSIBLE BY
EARLY NEXT WEEK.
DETAILS...
HIGH PRESSURE BRINGS CONTINUED DRY CONDITIONS FOR THE END OF
THE WEEK AND INTO THE WEEKEND. TEMPERATURES MODERATE ON FRIDAY
AND SATURDAY, WITH HIGH RANGING FROM THE LOW 60S ACROSS THE
NORTH TO UPPER 60S ALONG THE COAST BY SATURDAY. NIGHTTIME TEMPS
REMAIN COOL, WITH A FROST OR FREEZE LIKELY AGAIN THURSDAY NIGHT
AWAY FROM THE COASTLINE.
BY SUNDAY THE LOW PRESSURE CENTER MAKES SOME NORTHWARD PROGRESS
ALONG THE EAST COAST. AN EAST-NORTHEASTERLY WIND DEVELOPS ALONG
THE COAST, WITH HIGH CLOUDS INCREASING THROUGH THE DAY ACROSS
SOUTHERN AREAS. THIS KEEPS TEMPS A BIT LOWER ACROSS SOUTHERN
AREAS, GIVING GENERALLY LOW TO MID 60S ACROSS THE AREA, WITH
MORE SUNSHINE ACROSS THE NORTH.
BY EARLY NEXT WEEK MOISTURE MAKES NORTHWARD PROGRESS INTO NEW
ENGLAND. JUST HOW FAR NORTH AND HOW QUICKLY REMAINS IN QUESTION.
THE GFS REMAINS MORE PROGRESSIVE WITH MORE MOISTURE REACHING
THE AREA BY LATE SUNDAY AND MONDAY. THE EURO, IT'S ENSEMBLES,
AND AI MODELS GENERALLY HAVE LESS MOISTURE AND LATER NORTHWARD
PROGRESS UNTIL THE TUESDAY-WEDNESDAY TIMEFRAME, BUT ARE STARTING
TO SHOW SIGNS OF A NORTHWARD TREND WITH WEAKER BLOCKING TO THE
NORTH.
CURRENTLY POPS ALLOW FOR THE CHANCE OF RAIN STARTING SUNDAY
NIGHT AND INTO EARLY NEXT WEEK ACROSS SOUTHERN AND COASTAL
AREAS. SHOULD THE NORTHWARD TRENDS CONTINUE, THESE WOULD NEED TO
BE RAISED, AND COASTAL WINDS MAY ALSO HAVE TO BE MONITORED FOR
SOME STRONGER NORTHEASTERLY GUSTS.

THROUGH SUNDAY. NIGHTTIME VALLEY FOG IS POSSIBLE EACH NIGHT,
