BLIZZARD CONDITIONS WILL REMAIN LIKELY ACROSS SERN MA...INCLUDING THE CAPE AND ADJACENT ISLANDS. DISCUSSION...RADAR IMAGERY AS OF 1715Z ACROSS THE REGION DEPICTS SEVERAL BANDS OF ONGOING MODERATE TO HEAVY SNOW ASSOCIATED WITH A STACKED UPPER/SFC LOW ESE OF THE NEW ENGLAND COAST. TENDENCY WILL BE FOR THESE MESOSCALE BANDS TO SLOWLY SHIFT EWD TOWARDS THE COAST THROUGH 22Z AS THE UPPER/SFC LOW CONTINUE QUICKLY NEWD AND AWAY FROM THE MCD AREA. ACROSS WRN PORTIONS OF MA/CT...ONE OF THESE MESOSCALE BANDS IS STRUGGLING TO PRODUCE ANY MORE THAN MODERATE SNOW PER SFC OBSERVATIONS AND REPORTED SNOW TOTALS. THIS MAY BE DUE TO AN INTRUSION OF DRY LOW-LEVEL AIR EVIDENT ON THE 12Z KGYX SOUNDING AND IN RECENT SFC DEWPOINTS AOB 10 DEG F LOCATED IN THIS AREA. FURTHER E ACROSS THE DISCUSSION AREA...SFC DEWPOINTS ARE GENERALLY HIGHER...AND A STRONG NLY/NELY FETCH OFF THE ATLANTIC SHOULD ENCOURAGE HIGHER SNOWFALL RATES AROUND 1 INCH/HR. A STRONG PRESSURE GRADIENT AND NELY LOW-LEVEL JET...PARTICULARLY OVER SERN MA INCLUDING THE CAPE/ISLANDS...WILL CONTINUE TO PROMOTE NEAR-BLIZZARD TO BLIZZARD CONDITIONS ACROSS THIS REGION. RECENT SFC OBSERVATIONS INDICATE REDUCTIONS IN VISIBILITY AOB 1/4 MI WITH HEAVY SNOW AND SUSTAINED WINDS OF 20-35 KT...WITH GUSTS UP TO 45 KT AT KACK. ..GLEASON.. 02/08/2016 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
