ASSOCIATED WITH THIS SYSTEM WERE SEEN OVER THE MERRIMACK AND
WESTERN MAINE RIVER BASINS. ANY LINGERING PRECIPITATION THAT MAY
OCCUR TODAY WILL NOT AMOUNT TO MORE THAN A FEW HUNDREDTHS OF AN
INCH. FOR THE REST OF THE WEEKEND, THE NERFC AREA WILL REMAIN
PRECIPITATION FREE AS HIGH PRESSURE BUILDS INTO THE REGION. THE
NEXT CHANCE OF ANY SIGNIFICANT RAIN WILL BE ON MONDAY.

AN OCCLUDED FRONT IS PRESENTLY PROCEEDING ACROSS THE NERFC SERVICE
AREA, BRINGING AREAS OF HEAVY RAIN TO THE REGION. THIS SYSTEM
SHOULD AFFECT THE REGION FOR THE REST OF THE DAY ON FRIDAY, WITH
THE HEAVIEST RAINS EXPECTED IN PARTS OF THE MERRIMACK RIVER BASIN
AND THE WESTERN MAINE RIVER BASINS. BASIN-AVERAGE PRECIPITATION
TOTALS IN THESE AREAS ARE EXPECTED TO BE BETWEEN 0.75 AND 1.0
INCHES.
:
THE LOW PRESSURE CENTER ASSOCIATED WITH THIS FRONT WILL MOVE
FROM JUST NORTH OF LAKE ERIE THROUGH SOUTHERN QUEBEC DURING THE
NEXT DAY. AN AREA OF HIGH PRESSURE WILL BUILD OVER THE
NORTHEAST BEHIND THIS FRONTAL PASSAGE, WHICH WILL RESULT IN DRIER
WEATHER FOR THE UPCOMING WEEKEND.

PRECIPITATION SUMMARY:
:
AS THE OCCLUDED FRONT PROGRESSED ACROSS THE REGION ON THURSDAY AND
FRIDAY MORNING, SIGNIFICANT RAINFALL WAS OBSERVED OVER MUCH OF
NEW YORK STATE. 24-HOUR RAINFALL TOTALS FROM 1-2 INCHES WERE SEEN
