HYDROMETEOROLOGICAL DISCUSSION:
:
MID-MORNING WV ( WATER VAPOR ) IMAGERY SHOWS AN UPPER LEVEL
DISTURBANCE LOCATED ACROSS CENTRAL NEW YORK STATE WHICH IS
SWINGING AROUND A LARGER UPPER TROUGH IN SOUTHEAST CANADA. THIS
DISTURBANCE IS HELPING TO MAINTAIN A LINE OF SHOWERS AND
THUNDERSTORMS WHICH IS ENTERING THE ADIRONDACK MOUNTAINS AS OF 10
AM EDT. AS THIS UPPER LEVEL DISTURBANCE CONTINUES TO ROTATE
NORTHEAST...SHOWERS AND STORMS WILL BE LIKELY ACROSS MOST OF
NORTHERN NEW YORK STATE AND WESTERN...CENTRAL AND NORTHERN NEW
ENGLAND INTO EARLY TONIGHT. BASIN AVERAGE RAINFALL SHOULD BE
LIMITED TO AROUND 0.50 INCHES SINCE THE STORMS SHOULD BE
PROGRESSIVE BUT SOME INDIVIDUAL POINT RAINFALLS MAY APPROACH OR
EXCEED AN INCH THROUGH THIS EVENING.
:
LATER FRIDAY NIGHT INTO SATURDAY...A SLOW MOVING FRONTAL BOUNDARY
CREEPING NORTH FROM THE ATLANTIC WILL SET UP NEAR OR JUST SOUTH OF
LONG ISLAND AND THE NEW ENGLAND SOUTH COAST AND THAT COULD BRING
SOME LOCALLY HEAVY RAINS TO THOSE AREAS OVER THE WEEKEND...WITH
AMOUNTS POSSIBLY APPROACHING OR EXCEEDING AN INCH.
:
SOME LOCALLY HEAVY RAINFALL OCCURRED OVER THE LAST 24 HOURS ACROSS
EXTREME WESTERN NEW YORK STATE JUST NORTH OF BUFFALO. SEVERAL
AMOUNTS OF OVER 2.50 INCHES WERE REPORTED INTO THE NERFC THIS
MORNING WHICH INCLUDED 3.78 INCHES AT NIAGARA FALLS AIRPORT...3.24
INCHES IN PENDLETON AND 2.60 INCHES IN NORTH TONOWANDA. WE DO NOT
ANTICIPATE POINT RAINFALLS AS HEAVY AS THAT TODAY OR TONIGHT.
