PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE TAUNTON MA 
800 PM EST THU FEB 09 2017

NOTE...NEAR BLIZZARD CONDITIONS WERE STILL OCCURRING ON PARTS OF

REDUCES VISIBILITY TO BELOW 1/4 MILE ALONG WITH SUSTAINED WINDS OR 
WINDS THAT FREQUENTLY GUST TO 35 MPH OR MORE...AND THAT THESE ARE 
THE PREDOMINANT REPORTED CONDITIONS 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 PROVIDENCE RI...BLIZZARD CRITERIA WERE MET FOR 5 HOURS AND 
18 MINUTES...FROM 1051 AM TO 409 PM.

AT HYANNIS MA...BLIZZARD CRITERIA WERE MET FOR 5 HOURS AND

AND 32 MINUTES...FROM 1221 PM TO 453 PM.

AT BLOCK ISLAND RI...BLIZZARD CRITERIA WERE MET FOR 4 HOURS AND 
12 MINUTES...FROM 1149 AM TO 401 PM.

AT BEVERLY MA...BLIZZARD CRITERIA WERE MET FOR 3 HOURS AND 
57 MINUTES...FROM 1212 PM TO 409 PM.

AT MARSHFIELD MA...BLIZZARD CRITERIA WERE MET FOR 3 HOURS AND 
40 MINUTES...FROM 1215 PM TO 355 PM. 

AT NEW BEDFORD MA...BLIZZARD CRITERIA WERE MET FOR 3 HOURS AND 
38 MINUTES...FROM 1132 AM TO 310 PM.

AT WESTERLY RI...BLIZZARD CRITERIA WERE MET FOR 3 HOURS AND 
35 MINUTES...FROM 1153 AM TO 328 PM.

WE HAVE DETERMINED THAT BLIZZARD ALSO OCCURRED AT CHATHAM MA... 
PROVINCETOWN MA...AND NORTH SMITHFIELD RI. 

AT CHATHAM MA...BLIZZARD CONDITIONS BEGAN AT 107 PM AND CONTINUED 
THROUGH AT LEAST 336 PM WHEN COMMUNICATIONS ISSUES OCCURRED. HOWEVER 
THREE HOURS LATER VISIBILITIES WERE STILL 1/4 MILE AND WINDS WERE 
STILL STRONG.  

AT PROVINCETOWN MA...BLIZZARD CONDITIONS WERE CONFIRMED FROM 1256 PM 
THROUGH AT LEAST 356 PM BUT WINDS WENT MISSING AFTER 450 PM. 

AT NORTH SMITHFIELD RI...BLIZZARD CONDITIONS WERE REPORTED FROM 1056 
AM TO 108 PM BUT WINDS WENT MISSING AT THAT TIME. VISIBILITY 
CRITERIA WERE MET THROUGH 356 PM.

Just from the pics and other obs I have seen I have no idea how that NWS statement is accurate. I am not one who wants to ever trash the NWS but saying only one site verified makes no sense. It was a blizzard IMO.

Some thoughts signing off and dragging myself back to reality...

1) This was a blizzard. Objectively.

Continued thoughts signing off...

2) Wonder what you all think about model post-mortem... I thought NAM won here, big time. Sure it had it's usual apesh*t run yesterday, but overall, it was actually the closest verifying than the others. Euro was absolutely lagging. RGEM / CMC were atrocious.

Obviously we're not gonna crown NAM as the new king... this speaks more to the nature of this system than model dependability.

I agree, NAM led the way with this getting big snow back west of far Eastern CT.

 

Euro was lagging for sure with this one.

NAVGEM performed well in the medium range.
