WATER VAPOR IMAGERY SHOWS A SMALL UPPER-LEVEL LOW OVER SW ONTARIO. A
POWERFUL MID-LEVEL JET IS ROUNDING THE BASE OF THE ASSOCIATED
TROUGH. THE LINEAR MCS OVER NJ AND NY IS LOCATED IN THE LEFT EXIT
REGION OF THE JET AND THIS COMBINED WITH STRONG FORCING ASSOCIATED
WITH A SUBTLE SHORTWAVE TROUGH WILL SUSTAIN THE LINE NEWD ACROSS SRN
NEW ENGLAND THIS EVENING. HOWEVER...INSTABILITY HAS MARKEDLY
DECREASED ACROSS THE REGION SUGGESTING A DOWNTREND WITH THE
CONVECTION SHOULD CONTINUE. FOR ANOTHER HOUR OR TWO...THE STRONGER
CELLS COULD PRODUCE HAIL DUE TO STEEP MID-LEVEL LAPSE RATES AND
STRONG GUSTY WINDS DUE TO THE STRONG LOW-LEVEL FLOW.
