.SYNOPSIS...
COMPLEX LOW PRESSURE OVER THE MID-ATLANTIC REGION WILL TRACK
NORTHEAST OFF THE NEW ENGLAND COAST THROUGH TONIGHT. A COLD FRONT
SLIDING SOUTHEAST ACROSS THE GREAT LAKES AND ONTARIO PROVINCE WILL
WEAKEN AND DISSIPATE AS A WEAK RIDGE BEGINS TO BUILD IN ACROSS OUR

DOWN TO CHC POPS AT WORST...MAINLY NORTH OF ALB...AND WE HAVE CLOSE
TO ZERO POPS BY WEDNESDAY EVENING. COLD AIR MOVES IN ON THE BACK

WEDNESDAY. AIDED BY DOWNSLOPING...MERCURIES WILL BOUNCE BACK INTO
THE 40S AND 50S AT MOST LOCATIONS. BUT A MIXTURE OF EFFECTS FROM
COLD ADVECTION AND RADIATIONAL COOLING WILL SEND MERCURIES BACK DOWN
TO MOSTLY BELOW FREEZING WEDNESDAY NIGHT.
