What happened

The episode as NWS BTV wrote it up.

A very vigorous upper level disturbance ejected from south central Canada toward the Mid-Atlantic coast on February 22nd, which resulted in the development of a coastal storm south of New England by the afternoon. This storm rapidly intensified during the evening and night of the 22nd as it moved across Cape Cod into the Gulf of Maine. By the morning of February 23rd, a very intense storm system was slowly moving across Nova Scotia and New Brunswick into the Canadian Maritimes.

Light snow overspread Vermont during the morning of February 22nd and became moderate to heavy across much of central and eastern Vermont during the evening hours to early Monday Morning (23rd). Snowfall totals by the morning of the 23rd ranged from 6 inches in the Champlain Valley and southern Vermont to 10 to 18 inches across much of central and eastern Vermont. Some snowfall totals included; 20 inches in Sutton (Caledonia county), 19 inches in Newark (Caledonia), 16 inches in Lyndonville (Caledonia county), 14 inches in Canaan (Essex county), 13 inches in Cambridge (Lamoille county), Chelsea (Orange county), Marshfield (Washington county) and 12 inches in Windsor (Windsor county).

On February 23rd, wrap around moisture from the intense Canadian Maritime storm along with northwest winds created ideal up slope conditions across the higher terrain of northern Vermont. Snow redeveloped just after daybreak and ended just before Midnight.|Several inches of additional snowfall occurred in the northern valleys with 6 to 12 inches in higher terrain communities along the western slopes across the northern Green mountains (Eastern Franklin, Lamoille, western Orleans and eastern Chittenden counties).

In addition, brisk northwest winds 10 to 20 mph with gusts to 30 mph developed during the evening of February 22nd and continued through February 23rd. This resulted in considerable blowing and drifting of the snow which impacted travel across the region.

.SYNOPSIS...
SURFACE LOW PRESSURE ACROSS CENTRAL MICHIGAN WILL TRACK TOWARD
SOUTHERN CANADA TODAY...WHILE A SECONDARY AREA OF LOW PRESSURE
DEVELOPS NEAR LONG ISLAND THIS AFTERNOON. THESE TWO SYSTEM WILL
COMBINED TO PRODUCE PERIODS OF SNOW THROUGH TONIGHT...WHICH COULD BE
HEAVY AT TIMES ACROSS CENTRAL AND EASTERN VERMONT THIS EVENING. A
MODERATE TO SIGNIFICANT SNOWFALL EVENT IS EXPECTED FOR CENTRAL AND
NORTHERN VERMONT...AS WELL AS THE CHAMPLAIN VALLEY BY MONDAY
MORNING...WITH SLIGHTLY LESSER AMOUNTS ACROSS THE NORTHERN
ADIRONDACK MOUNTAINS. ACCUMULATING MOUNTAIN SNOW SHOWERS WILL
CONTINUE THROUGH TUESDAY FOR THE ADIRONDACK AND GREEN

TROF BASE ACRS CENTRAL KY ATTM WITH LATEST 3HR PRES FALLS
INDICATING WEAK SFC CYCLOGENESIS OCCURRING ON THE LEE SIDE OF THE
APPALACHIAN MTNS NEAR DC. VAPOR TRENDS SHOW POTENT S/W TROF
LIFTING ACRS THE CENTRAL GREAT LAKES WITH LIMITED SIGNS OF
WEAKENING OR TRANSFERRING ENERGY TO THE COAST YET.
FURTHERMORE...WATER VAPOR SHOWS PLENTY OF MID/UPPER LVL MOISTURE
ADVECTING FROM GULF COAST CONVECTION AHEAD OF DEEP FULL LATITUDE
TROF ACRS THE SE CONUS INTO THE MID ATLANTIC STATES...WHICH WL
EVENTUALLY BE PULLED BACK TWD OUR FA LATER TODAY...A TROF BECMGS
NEGATIVELY TILTED.

FOR THIS MORNING...FIRST BAND OF LIGHT SNOW WL MOVE ACRS OUR CWA
ASSOCIATED WITH GOOD DEEP LAYER MOISTURE AND SOME 850-500MB

PRODUCE A QUICK DUSTING TO 3 INCHES OF SNOW ACRS THE SLV/CPV AND
MOST OF VT WITH SLIGHTLY HIGHER AMOUNTS ACRS THE DACKS ASSOCIATED
WITH UPSLOPE SW FLW. MEANWHILE...A BRIEF BREAK IN THE PRECIP WL
DEVELOP FROM MID MORNING UNTIL EARLY AFTN...AS SECONDARY COASTAL
DEVELOPMENT OCCURS AND ENERGY TRANSFERS TO THE COAST. ONCE AGAIN THE
MILLION DOLLAR QUESTIONS WL BE HOW QUICKLY THE TRANSFER OCCURS...THE
EXACT TRACK/STRENGTH OF SFC LOW...AND DEVELOPMENT/EVOLUTION OF
CLOSED 7H/5H CIRCULATIONS. LATEST TRENDS...WHICH WE HAVE EXPERIENCED
ALL WINTER LONG...IS FOR THE PRIMARY SYSTEM TO HOLD ON
LONGER/STRONGER AND SECONDARY DEVELOPMENT TO OCCUR SLIGHTLY LATER

MODEL RUNS...WITH GREATEST QPF AXIS SHIFTED SLIGHTLY FURTHER EAST
ACRS CENTRAL/EASTERN VT. FURTHERMORE...STRONGEST 850-500MB LIFT AND

TRENDS...WHICH WOULD SUPPORT REDUCING SNOWFALL AMOUNTS ACRS THE CPV
TO 4 TO 8 INCHES. SOME CONCERN THE CPV MAYBE IN THE TRANSFER SPOT
BTWN PRIMARY LOW PRES TO THE NW AND SECONDARY DEVELOPMENT TO OUR
