MESOSCALE DISCUSSION 0128
   NWS STORM PREDICTION CENTER NORMAN OK
   0754 AM CST SAT FEB 09 2013
   
   AREAS AFFECTED...CENTRAL/EASTERN MA AND NH/MAINE
   
   CONCERNING...BLIZZARD 
   
   VALID 091354Z - 091800Z
   
   SUMMARY...HEAVY SNOWFALL AND BLIZZARD CONDITIONS WILL PERSIST
   THROUGH LATE MORNING/EARLY AFTERNOON ACROSS PORTIONS OF
   CENTRAL/EASTERN MA INTO NH/MAINE. SNOWFALL RATES ARE EXPECTED TO
   GRADUALLY DIMINISH...ALTHOUGH 2-3 IN/HR RATES WILL REMAIN POSSIBLE
   ESPECIALLY ACROSS COASTAL/EASTERN MAINE INTO EARLY AFTERNOON. THE
   PERSISTENCE OF VERY STRONG NORTHERLY WINDS WILL CONTINUE TO
   CONTRIBUTE TO CONSIDERABLE BLOWING/DRIFTING SNOW.
   
   DISCUSSION...CYCLONE CONTINUES TO GENERALLY SHIFT EAST-NORTHEASTWARD
   THIS MORNING...CENTERED OFF THE COAST OF MA AS OF 13Z. A MULTI-HOUR
   TREND OF WARMING CLOUD TOPS CONTINUES TO BE NOTED IN IR SATELLITE
   IMAGERY ACROSS MUCH OF NEW ENGLAND ASIDE FROM MAINE. THIS COINCIDES
   WITH THE EASTWARD SHIFT OF FORCED ASCENT AWAY FROM THE
   REGION...WHICH SHOULD LEAD TO DIMINISHING SNOWFALL RATES THROUGH THE
   MORNING. THAT SAID...A LONGER-LIVED/PIVOTING BAND ACROSS
   COASTAL/EASTERN MAIN WILL CONTINUE TO PRODUCE HEAVY SNOWFALL WITH
   2-3 IN/HR RATES POSSIBLE INTO EARLY AFTERNOON. THE 12Z OBSERVED
   SOUNDING FROM GRAY MAINE FEATURED A DEEPLY SATURATED/COLD
   THERMODYNAMIC PROFILE EFFICIENT FOR HEAVY SNOWFALL. EVEN WHILE
   SNOWFALL RATES MAY BEGIN TO DIMINISH BY LATE MORNING/EARLY
   AFTERNOON...VERY STRONG NORTH-NORTHEASTERLY WINDS WILL CONTRIBUTE TO
   CONSIDERABLE BLOWING AND DRIFTING SNOW AS WSR-88D VWP DATA FROM GRAY
   MAINE CONTINUES TO SAMPLE 60-65 KT WINDS WITHIN THE LOWEST 1-2 KM
   AGL.
