WE HAVE GONE BACK THROUGH OBSERVATIONS FROM SATURDAY JANUARY 7TH IN ORDER TO DETERMINE WHETHER A BLIZZARD OCCURRED ALONG THE SOUTH COAST. THE UPSHOT IS THAT A BLIZZARD WAS NOT OBSERVED AT ANY OF THE REPORTING STATIONS...BUT NEAR-BLIZZARD CONDITIONS DID OCCUR. THE DEFINITION OF A BLIZZARD IS THAT FALLING AND/OR BLOWING SNOW REDUCES VISIBILITY TO BELOW 1/4 MILE ALONG WITH WINDS THAT FREQUENTLY GUST TO 35 MPH OR MORE...AND THAT THESE CONDITIONS ARE THE PREDOMINANT REPORTED CONDITION FOR 3 CONSECUTIVE HOURS. WHEN REVIEWING WHETHER A PARTICULAR OBSERVATION LOCATION HAD BLIZZARD CONDITIONS...WE COUNTED VISIBILITIES EQUAL TO 1/4 MILE SINCE THAT IS QUITE LOW FOR AN AUTOMATED VISIBILITY SENSOR TO DETECT. AT MARSHFIELD MA...BLIZZARD CRITERIA WERE MET FOR A TOTAL OF 2 HOURS...FROM 655 PM TO 715 PM AND FROM 735 PM TO 915 PM. AT MARTHAS VINEYARD MA...BLIZZARD CRITERIA WERE MET FOR A TOTAL OF 37 MINUTES...FROM 353 PM TO 430 PM. AT BLOCK ISLAND RI...BLIZZARD CRITERIA WERE MET FOR A TOTAL OF 25 MINUTES...FROM 356 PM TO 421 PM. AT CHATHAM MA...BLIZZARD CRITERIA WERE MET FOR A TOTAL OF 14 MINUTES...FROM 252 PM TO 306 PM. AT NANTUCKET MA...VISIBILITIES WERE 1/4 MILE FOR NEARLY 4 HOURS AND WINDS FREQUENTLY GUSTED PAST 35 MPH FOR 11 HOURS...BUT THE STRONG WINDS WERE MAINLY AFTER THE VISIBILITIES HAD IMPROVED. THE WINDS AND LOW VISIBILITIES COINCIDED TO PRODUCE BLIZZARD CONDITIONS FOR ONLY 9 MINUTES...FROM 725 PM TO 734 PM. $$ FIELD
