CONCERNING...WINTER MIXED PRECIPITATION  
 
VALID 072321Z - 080315Z  
 
SUMMARY...HEAVY SNOW WILL MOVE FROM NEW HAMPSHIRE ACROSS SOUTHERN  
MAINE THIS EVENING. FREEZING RAIN WILL PERSIST FOR 2-3 HOURS ACROSS  
MASSACHUSETTS INTO SOUTHERN NEW HAMPSHIRE.  
 
DISCUSSION...A PROGRESSIVE SHORTWAVE TROUGH WILL CONTINUE TO QUICKLY  
MOVE ACROSS THE NORTHEAST THIS EVENING, WITH A SURFACE LOW MOVING  
FROM SOUTHERN NEW ENGLAND INTO NB/NS. STRONG WARM/MOIST ADVECTION IS  
OCCURRING AHEAD OF THIS WAVE, RESULTING IN A EXTENSIVE SHIELD OF  
PRECIPITATION. MOST OF THE AREA IS COLD ENOUGH FOR SNOW, BUT  
SOUTHERN AREAS FROM MA INTO COASTAL ME ARE EXPERIENCING FREEZING  
RAIN AS A RESULT OF A WARM NOSE ALOFT.  
 
RECENT OBSERVATIONS INDICATE 1"/HR SNOW RATES ARE COMMON FROM NH  
INTO ME, WITH HOURLY FREEZING RAIN RATES OF 0.05-0.10" OVER MA AND  
SOUTHERN NH. RAPID DRYING ALOFT WILL RESULT IN DISSIPATING  
PRECIPITATION FROM WEST TO EAST OVER THE NEXT FEW HOURS, WHILE  
STRONG LIFT AND THE BULK OF THE HEAVY SNOW MOVES ACROSS ME AND ENDS  
AROUND 04Z.
