The episode as NWS BTV wrote it up.
On March 6th, a slow moving north-south oriented cold front, laden with copious amounts of moisture, entered western Vermont by late morning, central Vermont around midday and eastern Vermont by late afternoon. In addition, a surface low in the Tennessee Valley tracked along this cold front to the mid-Atlantic states by evening, then the New York City vicinity during the early morning hours of March 7th and to the Maine-New Hampshire coast by late morning.
This surface low and cold front was responsible for severe weather along the Gulf coast states as well as flooding in the Tennessee and Ohio River Valleys on March 5th and 6th.
On March 5th into the morning hours of March 6th, temperatures were in the 40s across Vermont which promoted significant snow melt to the region.
On March 6th, heavy rainfall preceded the cold front as it moved across Vermont. The cold front crept across western Vermont during the late morning hours, temperatures fell 12-15 degrees within an hour and heavy rain changed to heavy sleet and then wet snow.
The cold front slowed across central Vermont during midday resulting in more rainfall (up to an inch) with a gradual changeover to sleet then snow. In eastern Vermont, heavy rainfall (1-2 inches) fell through early to mid-afternoon before colder air eventually filtered into the region...reaching the lower Connecticut River valley toward evening, where icing was the main hazard.
At the same time, rapid snow melt and heavy rainfall accounted for ice-covered rivers to swell and cause ice flows. There were several reports of ice jams and flooding related problems in the Passumpsic, Missisquoi and Winooski river valleys.
Heavy snow continued from the afternoon of March 6th to midday on March 7th with the heaviest occurring in the early morning hours of the 7th with snowfall rates of 1 to 3 inches per hour. Total snowfall accumulations ranged from 20 to 30 inches across much of the Champlain Valley and northern 1/3 of Vermont, 10 to 15 inches of snow with ice accumulation up to 1/4 inch in central Vermont and 2 to 6 inches of snow with 1/4 to 1/2 inch ice accumulation in the lower Connecticut River valley.
NWS Burlington office in South Burlington received 25.8 inches, a new March snowfall record and the 3rd highest snowfall total all-time.
Most roads were impassable with numerous accidents and stuck vehicles with portions of Interstate 89 closed multiple times. Burlington Int'l Airport was closed from midday on the 6th to midday on the 7th. Nearly 10,000 customers lost electrical power, nearly all school districts were closed on the 7th along with local/state governments.
Slightly more than a dozen dairy farms lost milk production due to trucks unable to reach farms and production facilities.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Burlington, VT wrote its last area forecast discussion before the first event at Mar 6, 6:39 AM EST, 1 hour 7 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
639 AM EST SUN MAR 6 2011
.SYNOPSIS...
A COLD FRONT WILL CONTINUE TO MOVE WEST TO EAST ACROSS OUR
FORECAST TODAY. THIS SYSTEM WILL BRING RAIN TO THE NORTH
COUNTRY...WHICH WILL CHANGE TO SNOW THIS AFTERNOON AND CONTINUE
THROUGH THE OVERNIGHT. A LOW PRESSURE AREA WILL DEVELOP ALONG
THIS FRONT ACROSS THE MID ATLANTIC STATES SUNDAY EVENING...AND
THEN MOVE SLOWLY NORTHEAST...REACHING CAPE COD BY EARLY MONDAY
NIGHT. THIS LOW HAS THE POTENTIAL TO BRING A SIGNIFICANT SNOWFALL
TO THE NORTH COUNTRY.
&&
.NEAR TERM /UNTIL 7 PM THIS EVENING/...
AS OF 445 AM EST SUNDAY...COLD FRONT IS CURRENTLY BISECTING OUR
NORTHERN NEW YORK ZONES...ALONG A LINE FROM ROUSES POINT TO
ELLENBURG...ST REGIS FALLS...AND SOUTHWEST THROUGH EDWARDS AND
FORT DRUM. TEMPERATURES ARE STILL WARM ENOUGH JUST BEHIND THE
FRONT THAT ALL PRECIP IS STILL IN LIQUID FORM. COLD AIR IS NOT
FAR BEHIND THOUGH AND AS COLD FRONT TRACKS EAST RAIN WILL CHANGE
OVER TO SNOW. THERE MAY BE A THIN LINE OF A MIX OF SLEET AND SNOW
AS THE CHANGEOVER TAKES PLACE. WINDS AHEAD OF THE FRONT ARE STILL
GUSTY OUT OF THE SOUTH...BUT WILL CHANGE TO NORTH AS FRONT PASSES
THROUGH. WE WILL HAVE EARLY MORNING MAX TEMPS THIS MORNING ACROSS
VERMONT AND PARTS OF NORTHERN NEW YORK...THEN WE WILL HAVE A
STEADY DROP IN TEMPS THROUGH THE DAY AS COLD AIR ADVECTION BEHIND
THE FRONT MOVES INTO THE AREA. SURFACE LOW WILL REDEVELOP NEAR
NYC LATE THIS AFTERNOON AND EVENING. BY 12Z IT SHOULD BE ALL SNOW
ACROSS THE SAINT LAWRENCE VALLEY. SNOW CONTINUES TO FILTER EAST
AND BY 18Z IT SHOULD BE ALL SNOW ACROSS NORTHERN NEW YORK...THE
CHAMPLAIN VALLEY AND MOST OF THE REST OF NORTHERN AND CENTRAL
VERMONT...MINUS THE AREA EAST OF THE GREENS AND ALSO SOUTHERN
VERMONT. BY 7 PM SNOWFALL TOTALS SHOULD BE AROUND 3 TO 7 INCHES
WITH THE HIGHEST AMOUNTS IN THE ADIRONDACKS. PLEASE SEE HYDRO
DISCUSSION FOR HYDRO CONCERNS.
&&
.SHORT TERM /7 PM THIS EVENING THROUGH TUESDAY/...
AS OF 500 AM EST SUNDAY...COLD AIR WILL CONTINUE TO SPREAD SOUTH
AND EAST ACROSS THE FORECAST AREA...AND ALL REMAINING RAIN AND
SLEET WILL CHANGE TO ALL SNOW OVERNIGHT. COASTAL LOW WILL TRACK
NORTHEAST TOWARDS CAPE COD AND SNOW WILL OCCASIONALLY BE HEAVY AT
TIMES WITH FRONTOGENESIS OF COASTAL LOW. IT STILL LOOKS LIKE 1 TO
2 INCHES OF QPF CAN BE EXPECTED WITH THIS SYSTEM BY MONDAY
EVENING. GFS SEEMED THE MOST REASONABLE FOR PRECIP...WITH
COMPARING TO PRECIP TOTALS THAT WE HAVE ALREADY SEEN. MILD AIR
WILL HOLD ON THE LONGEST IN SOUTHERN VERMONT...BUT HAVE GONE WITH
A WINTER STORM WARNING FOR ALL COUNTIES NOW BECAUSE NORTHERN
PARTS OF RUTLAND...WINDSOR AND ORANGE COUNTIES WILL MEET WARNING
CRITERIA TONIGHT. SNOW WILL TAPER OFF IN THE SAINT LAWRENCE
VALLEY OVERNIGHT...THUS LIMITING SNOWFALL TOTALS IN THAT AREA.
NORTHERN ADIRONDACKS AND NORTHERN VERMONT WILL HAVE MOST
PERSISTENT SNOW THROUGH THE EVENT...HAVE DEPICTED A LARGE SWATH
OF 8 TO 12 INCHES ACROSS MUCH OF THE AREA WHERE THE SNOW WILL BE
MOST PERSISTENT. SURFACE LOW WILL PULL EAST AND PRECIP WILL CUT
OFF FAIRLY SHARPLY FROM WEST TO EAST ACROSS THE FORECAST AREA.
SOME ADDITIONAL ACCUMULATIONS ARE POSSIBLE ACROSS EASTERN
VERMONT...BUT DRIER AIR WILL BRING CLEARING DURING THE AFTERNOON
AND PRECIP SHUTS DOWN AREAWIDE.
MONDAY NIGHT AND TUESDAY WILL BE DRY WITH COLDER THAN NORMAL
TEMPERATURES MONDAY NIGHT WITH CAA IN PLACE AND AS SKIES BECOME
CLEAR ALLOWING SOME RADIATIONAL COOLING. THEN TUESDAY WILL ALSO
BE A BIT BELOW NORMAL WITH COLD SURFACE HIGH PRESSURE RIDGING
INTO THE NORTH COUNTRY OUT OF CANADA.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
AS OF 330 AM EST SUNDAY...QUIET WEATHER TO START THE EXTENDED
PORTIONS OF THE FORECAST TUESDAY NIGHT AS SFC HIGH PRESSURE AND
LARGE-SCALE SUBSIDENCE REMAIN ATOP THE AREA. WITH CLEAR SKIES AND
LIGHT WINDS DECENT LONGWAVE RADIATIVE EFFECTS SHOULD DOMINATE
ONCE AGAIN WITH CHILLY OVERNIGHT LOWS GENERALLY IN THE 5 BELOW TO
10 ABOVE RANGE.
CLOUDS THEN SLOWLY INCREASE/THICKEN OVER TIME DURING WEDNESDAY AS
HIGH MOVES EAST AND AMPLIFIED ENERGY FROM THE OHIO VALLEY/GREAT
LAKES PUSHES EAST. BETTER DYNAMICS AND MOST OF THE PCPN WITH THIS
FEATURE SHOULD STILL BE MAINLY TO THE WEST OF OUR AREA HOWEVER SO
DESPITE THICKENING CLOUDS MAINLY DRY WEATHER EXPECTED. WITH
RETURN SOUTHERLY FLOW BEGINNING IN EARNEST...AFTERNOON TEMPS
SHOULD CLIMB BACK TOWARD SEASONABLE LATE WINTER NORMS WITH HIGHS
GENERALLY IN THE MID TO UPPER 30S. AS UPPER TROUGH AND ATTENDANT
SFC FRONT PUSH INTO THE REGION WEDNESDAY NIGHT INTO THURSDAY PCPN
CHCS INCREASE FROM WEST TO EAST ACROSS THE AREA. WILL HIGHLIGHT
MAINLY SNOW SHOWERS WITH INITIAL PCPN ARRIVAL WED NT...BUT GIVEN
INCREASING SOUTHERLY FLOW WOULD NOT BE SURPRISED TO SEE MIX OR
PLAIN RAIN SHOWERS IN TYPICAL MILDER SPOTS SUCH AS THE SAINT
LAWRENCE/CHAMPLAIN VALLEYS OVERNIGHT AS TEMPERATURES ONLY FALL
SLIGHTLY FROM EARLIER AFTERNOON HIGHS. BY THURSDAY A MIX OF
RAIN/SNOW SHOWERS STILL LOOKS LIKE A GOOD BET AS PRIMARY UPPER
SYSTEM NEARS. DECENT SOUTHERLY MOISTURE TRANSPORT ARGUES A
PERSISTENCE FCST HERE OF LIKELY POPS AREA WIDE AS TEMPS CLIMB
INTO THE 35 TO 40 DEGREE RANGE.
THEREAFTER FCST BECOMES MORE UNCERTAIN AS MODELS ONCE AGAIN ARE
HINTING AT STRUGGLES ON HOW TO HANDLE ADDL SOUTHERN STREAM ENERGY
RIDING NORTHWARD ALONG FRONTAL BOUNDARY. GFS CLOSES OFF UPPER
ENERGY SOUTH OF OUR REGION ACROSS THE MID ATLANTIC...WHILE THIS
MORNING'S EURO OP RUN WOULD SUGGEST A MORE PROGRESSIVE TRACK NEAR
OR ACROSS OUR AREA. REGARDLESS...PLENTY OF TIME TO PIN DOWN
SPECIFICS SO WILL COMPROMISE WITH CHC POPS INTO FRIDAY...THEN
TAPER OFF THEREAFTER.

.HYDROLOGY...
AS OF 330 AM EST SUNDAY...THE COMBINATION OF WARMER
TEMPERATURES...SNOWMELT AND MODERATE TO LOCALLY HEAVY RAINFALL
WILL PRODUCE RISES ON LOCAL WATERWAYS THROUGH SUNDAY. AS A
RESULT...WHILE MAINSTEM RIVER FLOODING IS NOT
EXPECTED...CONFIDENCE IS FAIRLY HIGH THAT MODEST TO SIGNIFICANT
WITHIN-BANK RISES WILL OCCUR TODAY INTO THIS EVENING. THIS WILL
LIKELY ALLOW FOR MOVEMENT OR PARTIAL BREAK-UP OF RIVER ICE IN
SOME AREAS THAT COULD LEAD TO THE DEVELOPMENT OF ICE JAMS. AS
ALWAYS...THE DIFFICULTY LIES IN PREDICTING WHERE THIS MAY
HAPPEN. DUE TO THE TYPICAL DELAYED RESPONSE OF RUNOFF DURING
PRECIPITATION EVENTS...THE BEST THREAT OF ICE MOVEMENT AND
POTENTIAL ICE JAMMING WOULD APPEAR TO OCCUR TODAY INTO THIS
EVENING...PARTICULARLY ALONG SMALLER TRIBUTARIES IN THE CHAMPLAIN
AND SAINT LAWRENCE VALLEYS...AND POSSIBLY ALONG THE LOWER REACHES
OF MAINSTEM RIVERS ENTERING THESE VALLEYS. INDEED...AS OF 500 AM
SHARP RISES HAVE BEEN NOTED ACROSS FRANKLIN COUNTY VERMONT...
PARTICULARLY ALONG THE ROCK RIVER AND TRIBUTARIES OF THE
MISSISQUOI RIVER WHERE A FLOOD ADVISORY IS IN EFFECT THROUGH LATE
MORNING. SOME CONCERN ALSO EXISTS ACROSS SOUTHERN VERMONT WHERE
TEMPERATURES WILL REMAIN MILDER THROUGH MID TO LATE AFTERNOON
TODAY. THUS CONDITIONS WILL CONTINUE TO BE MONITORED CLOSELY.
