Btw, just when we thought it was safe to put the snow shovel back in the garage... it kept snowing this evening, even with the moon appearing from behind the clouds.

Nearly another half inch brings this latest storm total to 10.4 inches... our second biggest dumping of the season/month so far, after the Dec. 3 storm. And to think this wasn't even a well-hyped Nor'Easter or anything like that, just a measly little inverted trough extending from a system well offshore. Welcome to New England.
CLA,
Isn't the phenomenon of the Norlun Trough fascinating? Walt Drag of the Boston NWS office was the only one to pull the trigger on the extent of what it would do and the significant accumulations and he did it Wed afternoon. Here is what he posted Wed late afternoon:
.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
-- Changed Discussion --AS YOU ARE PROBABLY AWARE...MODEL TEMPERATURES IN THE BOUNDARY LAYER ARE
SLIGHTLY TOO WARM THIS EVENING. THAT MEANS TROUBLE FOR THIS FCST ISSUANCE...THINK
MORE SNOW AND COLDER.


WE`VE PARTIALLY RECOGNIZED THIS PROBLEM IN MIDDAY UPDATES... BUT IF THE
18Z MODEL RUNS ARE CORRECT...WE`RE GOING TO END UP WITH SUBSTANTIALLY
MORE SNOW BOSTON ALONG THE COAST TO NEWBURYPORT THAN ISSUED AT 4 PM.

BE ALERT FOR A POSSIBLE UPGRADE ON 4AM THURSDAY FCST TO A WARNING 8
INCH SNOWFALL IN PARTS OF ESSEX COUNTY MASS AND EASTERN HILLSBOROUGH
COUNTY NH. WE ARE NOT OFFICIAL ON THIS YET SINCE INTERIM NCEP MODEL
RUNS ARE THE ONLY BIG CHANGE ON QPF AND WE WANT 00Z RUNS TO FALL IN
LINE WITH THIS.

RIGHT NOW WE STAY WITH ADVISORIES AS POSTED BUT THE BATCH OF SNOW COMING
INTO SW CT AT 530 PM IS GOING TO GO STATIONARY TOMORROW MORNING IN NE MASS
AND S CENTRAL NH AND WITH LARGE DENDRITIC GROWTH I CAN SEE ANOTHER 6+
SNOW EVENT.
