What happened

The episode as NWS BOX wrote it up.

A major winter storm impacted northern Connecticut with heavy snow and strong winds. The slow-moving storm, which tracked south of New England, dumped 10 to 20 inches of snow across Hartford, Tolland, and Windham counties and knocked out power to tens of thousands of customers. Schools and businesses were shut down for three days in some communities. Officially, Bradley International Airport in Windsor Locks reported a storm total of 9.9 inches. Other reports from Hartford County include 15 inches in Farmington, 14 inches in East Windsor, Burlington, and Wethersfield, 13 inches in Glastonbury, and 12 inches in Manchester. In Tolland County, 16 inches of snow fell in Stafford, 15 inches in Tolland, 14 inches in Vernon, and 11 inches in Mansfield. In Windham County, East Killingly reported 15 inches, Andover 13 inches, and Putnam, Willimantic, and Pomfret all had 12 inches of snow.

...THIS STORM APPEARS TO BE NOT PANNING OUT QUITE AS EXPECTED...

TRAVEL: COASTAL ROUTES WILL WORK OUT FINE TODAY AND PROBABLY THIS
        EVENING.

RECOVERY: SHUD NOT BE AS DIFFICULT AS ANTICIPATED YDY S OF BOSTON.

BLIZZARD WARNING: DROPPED IN BOSTON PROPER BUT CONTD NW SUBURBS...CUT
WAY BACK ON AMTS ON SE NEW ENGLAND. THIS DOES NOT MEAN IT CANT HAPPEN
BUT IT S GOING TO TAKE LONGER AND ODDS ARE LESS FOR A BLIZZARD THAN
OUR EARLIER FCSTS STATED. MOST LIKELY REGION FOR OCCURENCE IN MERR
VLY NEWBURYPORT TO LWM AND MHT AND MAYBE ORH. AM NOW CONCERNED ABOUT
GETTING WIND DONW IN THERE.

HEAVY OR VERY HEAVY SNOW WILL OCCUR IN BOSTONS NORTHERN AND WESTERN
SUBURBS W AND N TO ORH-HFD NORTHWARD WHILE IN THE CORRIDOR SFC-IJD-
OWD-NZW MQE-BOS AM CONCERNED ABT MOSTLY ZR/IP/WET S MIX.

SOUNDINGS AT BOSTON ARE IN OUR OPINION DANGEROUS CLOSE TO ALL SNOW...
EVEN THE WARMER ETA...BUT TOO LARGE A LAYER NEAR 0C...MAY BE TOO
MUCH FOR THE COMMA HEAD TO OVERCOME. WE WILL KNOW AT 8 PM.

WE ALSO CAUTION THAT RAPID STORM DVLPT IS OCCURING AND IT WILL STILL
BE A SERIOUS IMPACT STORM FROM THE MERRIMACK VALLEY THROUGH ORH AND
I84 NORTHWARD. XPCTING SFALL RATE OF 1 TO POSSIBLY 3" PER HR 22Z-04Z
WITH RISK ISOLATED THUNDER.

WE LIKE THE AVN UVM INTIALIZATION THIS AM AS C0MPARED TO
REFLECTIVITY.

BLV STG UVM THIS AFTN WILL COMPENSATE FOR NEAR FREEZING SOUNDINGS
AND TURN LGT MXD PCPN BACK TO SNOW/SLEET MIX DOWN TO NZW-PVD LN AND
TO ALL SNOW IN BOS PTS N AND W. HOW LONG THAT UVM CAN COMPENSATE WE
DONT KNOW. TNGT THE SOUNDINGS TEND TO COOL SLIGHTLY BUT THE GOOD

UNCOMFORTABLY CLOSE TO BOS AND WHILE MXD PCPN WAS ANTICIPATED FOR A
FEW HRS TDY TO MA PIKE REGION...UNCOMFORTABLE ABOUT FCST AS BEING TOO
STRONGLY WORDED.

18Z CHH SOUNDING MAY B HELFPUL IN ETA/NGM DECISION..ESPECIALLY
