.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
HIGH PRESSURE WILL MOVE OFFSHORE MONDAY NIGHT AND A WARMER
SOUTHWEST FLOW WILL DEVELOP AHEAD OF A WEAK COLD FRONT SAGGING
SOUTHWARD FROM QUEBEC. CLOUDS WILL INCREASE LATER IN THE NIGHT.
LOWS WILL GENERALLY BE IN THE LOW 30S WITH A FEW UPPER 20S
POSSIBLE IN THE NORMALLY COLDER LOCATIONS. THE COLD FRONT WILL
MOVE INTO NORTHERN ZONES DURING THE MORNING WITH JUST A FEW
HUNDREDTHS OF AN INCH OF RAINFALL. HIGHS WILL REACH THE UPPER 50S
TO NEAR 60F FOR SOUTHERN PORTIONS OF THE FORECAST AREA AND LOWER
50S NORTH WHERE FRONTAL CLOUD COVER WILL BE DENSER. AS THE PARENT
LOW FILLS IN QUEBEC...THE COLD FRONT WILL ALSO WEAKEN AND STALL
ACROSS THE FORECAST AREA. SOME CLEARING WILL OCCUR OVERNIGHT AND ALLOW
TEMPERATURES TO FALL INTO THE MID TO UPPER 30S.

ANOTHER LOW PRESSURE SYSTEM WILL MOVE ALONG THE STALLED FRONT
TOWARDS THE FORECAST AREA ON TUESDAY. THIS LOW WILL DEEPEN DURING
THE DAY AS UPPER LEVEL FORCING INCREASES AND IT WILL SLOWLY TRACK
INTO THE REGION ON TUESDAY NIGHT. A VERY STRONG UPPER LEVEL JET
APPROACHING FROM THE NORTHWEST WILL CAUSE THE LOW TO FURTHER
DEEPEN ON TUESDAY NIGHT INTO WEDNESDAY AND THEN BECOME A CUT-OFF
LOW OFF THE NEW ENGLAND COAST. THIS WILL KEEP CLOUDS AND RAIN IN
THE AREA THROUGH THURSDAY WITH HIGH IN THE LOW 50S AND LOWS IN THE
UPPER 30S. HIGH PRESSURE WILL FINALLY RETURN LATER THURSDAY AND
BUILD THURSDAY NIGHT. RAINFALL AMOUNTS COULD ADD UP TO WELL OVER
AN INCH FROM TUESDAY NIGHT INTO THURSDAY MORNING AND KEEP HYDRO
CONCERNS GOING THROUGH THE WEEK AS REMAINING SNOW MELTS AND KEEPS
RIVERS ELEVATED. AM LEANING TOWARDS THE ECMWF SOLUTION WITH THE
CONCERN THAT THE GFS MOVES THE CUT-OFF EASTWARD TOO RAPIDLY.
