HIGH PRESSURE REMAINS CENTERED OVER NEW ENGLAND THROUGH TONIGHT
AND DRIFTS OFFSHORE TUESDAY AS A WEAK LOW PRESSURE SYSTEM

COAST THROUGH TUESDAY, WITH THE UPPER RIDGE GRADUALLY WEAKENING.
THE SURFACE HIGH ALSO BEGINS TO SLOWLY WEAKEN AND SHIFT OFFSHORE
DURING TUESDAY AFTERNOON. LEANED TOWARD THE NBM PROBABILITIES
FOR PRECIPITATION MOVING INTO THE SOUTHERN REGION TUESDAY
AFTERNOON, HOWEVER, WITH MOST CAMS HOLDING OFF ON PRECIPITATION
UNTIL TUESDAY EVENING LOWERED POPS THROUGH THE AFTERNOON AND
CUTBACK ON NORTHERN EXTENT. THE UPPER LOW CONTINUE TO MEANDER
THROUGH TUESDAY NIGHT AND INTO WEDNESDAY BEFORE OPENING INTO A
SHORTWAVE LATE WEDNESDAY INTO WEDNESDAY NIGHT, AND BECOMING
RATHER FLAT AS THE LOW MOVES INTO THE UPPER RIDGE. CHANCES OF
PRECIPITATION WILL CONTINUE TUESDAY INTO WEDNESDAY NIGHT,

PRECIPITATION WILL BE LIGHT, WITH UP TO A QUARTER OF AN INCH
POSSIBLE ALONG THE COAST, AND A FEW HUNDREDTHS FARTHER NORTH.
LONG TERM /THURSDAY THROUGH MONDAY/
A FEW SHWRS ARE POSSIBLE ON THU AS THE OFFSHORE LOW BEGINS TO
MEANDER OUT TO SEA. ALTHOUGH MOISTURE IS LIMITED, STEEP LAPSE

ENTIRE CWA DOWN. DRY FOR THE WEEKEND WITH COOLER TEMPS. COMPARING
THE NBM TO THE MEX, THE NBM MAY BE TO WARM. IN FACT, AT THIS TIME

TO SEE SOME OF THE NRN AND ERN AREAS STAY IN THE UPR 60S SAT AND
SUN, ALBEIT WITH LOTS OF SUNSHINE ESPECIALLY SAT.
