EXPECTED TO FORM IN THE CONNECTICUT RIVER VALLEY TONIGHT. LOWS  
TONIGHT WILL FALL BACK INTO THE 50S AND HIGHS ON THURSDAY WILL RISE

MAINLY DRY EXCEPT THERE IS THE RISK FOR SHOWERS ACROSS WESTERN AND  
NORTH CENTRAL MASSACHUSETTS. LOWS WILL FALL BACK INTO THE 50S.  
 
IT WILL BE WARMER ON FRIDAY AHEAD OF AN APPROACHING COLD FRONT WITH
