HYDROMETEOROLOGICAL DISCUSSION:
:
THE STRONG STORM SYSTEM THAT BROUGHT HEAVY RAINFALL TO MUCH OF
EASTERN NEW YORK STATE AND NEW ENGLAND OVER THE PAST 24 HOURS AND
ACCUMULATING SNOW ON THE BACK END HAS PUSHED EAST OF THE NEW
ENGLAND COAST NOW. THE LAST OF THE SNOW IS EXITING FAR DOWNEAST
MAINE AND OTHERWISE...SOME LAKE EFFECT SNOWSHOWERS SOUTH OF LAKE
ONTARIO AND SOME LIGHT SNOWSHOWERS IN THE MOUNTAINS OF NORTHERN
NEW ENGLAND WILL END BY EARLY THIS AFTERNOON. HIGH PRESSURE WILL
BUILD ACROSS THE REGION THIS AFTERNOON AND TONIGHT AND WE EXPECT
FAIRLY BENIGN WEATHER INTO FRIDAY. THE NEXT CHANCE FOR SHOWERS
WILL COME LATE FRIDAY AND FRIDAY NIGHT ACROSS NEW YORK STATE AND
NORTHERN NEW ENGLAND AS A COLD FRONT APPROACHES FROM THE WEST.
RAINFALL AMOUNTS DO NOT LOOK IMPRESSIVE WITH THIS SYSTEM RIGHT NOW
