AREAS AFFECTED...CENTRAL AND NORTHERN NEW ENGLAND...NORTHERN NEW
YORK...
CONCERNING...WINTER MIXED PRECIPITATION
VALID 131315Z - 131915Z
SUMMARY...A MIX OF SNOW...SLEET AND FREEZING RAIN WILL MOVE ACROSS
NORTHERN NEW YORK AND CENTRAL NEW ENGLAND THIS MORNING. FREEZING
RAIN RATES COULD EXCEED 0.03 INCHES PER HOUR IN SOME AREAS. HEAVY
SNOW COULD DEVELOP IN SOME AREAS ACROSS CENTRAL AND NORTHERN MAINE.
DISCUSSION...HEIGHTS WILL FALL ACROSS THE NORTHEAST TODAY, AS A
MID-LEVEL TROUGH APPROACHES FROM THE WEST. SEVERAL AREAS OF
PRECIPITATION ARE ONGOING IN THE NORTHEAST. THIS IS BEING SUPPORTED
BY LARGE-SCALE ASCENT AHEAD OF THE TROUGH, AND BY STRONG LOW-LEVEL
JET CURRENTLY LOCATED IN NORTHERN NEW YORK. AT THE SURFACE, A STRONG
THERMAL GRADIENT IS PRESENT WITH TEMPERATURES IN NEW ENGLAND RANGING
FROM THE LOWER TO MID 30S F OVER SOUTHERN AND CENTRAL NEW ENGLAND,
AND TEENS TO SINGLE DIGITS OVER CENTRAL AND NORTHERN MAINE. IN
ASSOCIATION WITH THE LOW-LEVEL JET, A NOSE OF WARM AIR ALOFT IS
EVIDENT ON FORECAST AND OBSERVED SOUNDINGS. THIS WARM NOSE, WITH
TEMPERATURES OF 2 TO 5 C, WILL FAVOR A MIXED PRECIPITATION TYPE FROM
NORTHERN NEW YORK EASTWARD ACROSS NORTHERN NEW ENGLAND INTO SOUTHERN
MAINE. FREEZING RAIN WITHIN THIS ZONE COULD EXCEED 0.03 INCHES PER
HOUR WITHIN THE HEAVIER POCKETS OF PRECIPITATION. TO THE NORTH OF
THE ZONE, AIR ALOFT WILL BE COLD ENOUGH FOR SNOW. LOCALIZED HEAVY
SNOW WILL BE POSSIBLE, MAINLY ACROSS PARTS OF CENTRAL AND NORTHERN
MAINE.
