What happened
The episode as NWS GYX wrote it up.
An area of low pressure located over the Upper Mississippi River Valley on the morning 11th moved northeastward to the Great Lakes on the morning of the 12th. A secondary low formed along the mid-Atlantic coast during the day on the 12th, then moved slowly northeastward along the coast and was located in the Gulf of Maine by the morning of the 13th and then southeast of Nova Scotia by the morning of the 14th. The late season storm brought heavy snow to much of the state. Snowfall amounts ranged from 4 to 8 inches along the coast to 10 to 15 inches in the mountains.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
1104 AM EDT THU APR 12 2007
.SHORT TERM /REST OF TODAY/...
HAVE UPDATED TO INCLUDE THE MID COAST OF MAINE TO WARNINGS BASED
ON SOME OF THE NEW 12Z NAM. THE COLUMN REMAINS COLD...AND WHEN THE
PRECIPITATION FALLS MORE HEAVILY THIS AFTERNOON AND EVENING IT
SHOULD FALL AS SOON.
THERE MAY BE A LULL IN THE PRECIPITATION...WOULD COULD FALL AS
RAIN AND SLEET FOR A TIME. NO OTHER SIGNIFICANT CHANGES TO THE
FORECAST AT THIS TIME.
&&
.PREV DISCUSSION... /ISSUED 1009 AM EDT THU APR 12 2007/
SHORT TERM /REST OF TODAY/...
CONTINUING TO MONITOR THE DEVELOPING SITUATION. AT THE MOMENT...NO
CHANGES TO CURRENT FORECAST...BUT THIS MAY CHANGE SHORTLY AS THE
DEPTH OF THE WARM LAYER IS BEING EVALUATED. REPORT OF SLEET IN
KEENE IS PUTTING A MONKEY WRENCH INTO THE FORECAST...AS NO MODEL
SOUNDINGS ARE SHOWING.
THIS COULD BE DUE TO THE FACT THAT THE PRECIPITATION HAS LIGHTENED
UP...AND THE WARM LAYER IS ALLOWED TO DOMINATE. AS THE BEST VERTICAL
MOTION REDEVELOPS IN THE WARM AIR ADVECTION...THE COLUMN SHOULD
COOL BACK TO ISOTHERMAL. THIS WILL BE A KEY IN THE PRECIPITATION
TYPE FORECAST FOR THIS AFTERNOON.
A REVIEW OF THE MORNING UPPER AIR SUGGESTS THAT THE COLUMN IS
INITIALLY COLDER THAN FORECAST. BASED ON THE 06Z MODEL RUN QPF AND
THE COLDER SOUNDINGS...CONSIDERING UN UPGRADE OF THE ADVISORY TO A
WINTER STORM WARNING FOR INTERIOR SECTIONS OF SOUTHEAST NEW HAMPSHIRE...
AS WELL AS THE MAINE COAST FROM PORTLAND TO ROCKLAND. THIS WOULD
BE FOR 4 TO 8 INCHES OF SNOW...AS THE VERTICAL MOTION OVERCOMES
THE WARMING FROM THE OCEAN.
WILL ALSO UP ACCUMULATIONS FOR INTERIOR SECTIONS OF MAINE AS QPF
FORECASTS SUPPORT UP TO 10 INCHES OF SNOW FOR THIS AREA. AGAIN...STILL
WORKING ON THE DETAILS...AND AN UPDATE WOULD BE OUT BEFORE 1045
AM.
PREV DISCUSSION... /ISSUED 235 AM EDT THU APR 12 2007/
SHORT TERM /TODAY THROUGH TONIGHT/...
SECONDARY LOW FORMS OFF MID ATLANTIC COAST AND AWAY WE GO. NOT MUCH
CHANGE IN 00Z MODEL SOLUTIONS FROM PREVIOUS RUNS...SO PLAN ON
CONTINUING FORECAST/WARNINGS/ADVISORIES INTACT FOR THE MOST PART
WITH A FEW MINOR TWEAKS. STILL LOOKS LIKE CORRIDOR OF STRONGEST
WINDS WILL BE COMING OVER THE CAPE...SOUTH OF OUR FORECAST AREA.
TRAVEL WILL BECOMING CHALLENGING OVER WESTERN FORECAST AREA BY
NOONTIME AND BY DRIVE TIME OVER EASTERN FORECAST AREA. WET SNOW
WILL CAUSE POWER OUTAGE CONCERNS. SYSTEM PULLS OUT FROM WEST TO EAST
OVERNIGHT. USED MOS/MET/CURRENT FORECAST FOR TEMPERATURES AND ADJUSTED
MAVS FOR POPS.
LONG TERM /FRIDAY THROUGH WEDNESDAY/...
WOW...HERE WE GO AGAIN?
UNSTABLE CONDITIONS WILL CONTINUE IN THE MOUNTAINS FRIDAY AND
FRIDAY NIGHT ALONG/NEAR AN INVERTED TROUGH. PLENTY OF LOW LEVEL
MOISTURE AND SOME UPSLOPE COMPONENT...ALONG WITH STEEP LAPSE RATES
WILL ALLOW FOR ACCUMULATING SNOW TO FALL ACROSS THE HIGH TERRAIN.
SAT...A BRIEF BREAK FROM THE ACTION...THEN EVERYTHING MAY BREAK LOOSE.
SUN...ONE LAST GASP TO WINTER...AND A HEALTHY ONE AT THAT. MODELS IN
FAIRLY GOOD AGREEMENT BRINGING INTENSIFYING LOW TO THE MID ATLC
REGION BY SUNDAY. LOW FORECAST TO MOVE UP THE COAST AND BECOME
NEARLY STATIONARY JUST SOUTH OF LONG ISLAND NEW YORK...BEFORE
DOING A CLASSIC LOOP IN THE SAME VICINITY SUNDAY NIGHT AS UPPER
LOW CAPTURES SYSTEM. WHAT A SPRING. WILL APRIL SNOWFALL RECORDS
FALL? ALL-TIME SNOWIEST FOR THE FOREST CITY IS 20.5 INCHES WAY
BACK IN APRIL 1906. 30 YEAR AVERAGE FOR PORTLAND IS 3.2 INCHES.
HAVE UPPED WINDS AND SEAS FOR DAY 4...HOWEVER LEFT ROOM FOR
ADJUSTMENTS AT TRACK/INTENSITY WILL LIKELY CHANGE WITH TIME.
COASTAL FLOOD POTENTIAL: IF TRACK/INTENSITY HOLDS...THERE WILL
BE PROBLEMS ALONG THE COAST (MAINLY SOUTH OF PORTLAND) SUNDAY
NIGHT AND MONDAY. MONDAY WOULD BE THE MOST VULNERABLE TIME FOR AND
COASTAL FLOODING...SPLASH-OVER AND BEACH EROSION AS LARGE...HIGH
ENERGY OCEAN WAVES WOULD HAVE HAD TIME TO DEVELOP AND COMBINE WITH
AN INCREASING ASTRONOMICAL HIGH TIDE.. ASTRONOMICAL TIDES INCREASE
WITH TIME DURING THE PERIOD SUNDAY NIGHT...RIGHT THROUGH MIDWEEK.
HAVING SAID ALL THIS...ITS STILL EARLY AND WE HAVE A COUPLE MORE
DAYS TO REVIEW THIS POTENTIAL.
AVIATION...VFR TO START...FALLING TO MVFR FROM WEST EAST LATER
THIS MORNING...DOWN TO IFR/LIFR LATER THIS AFTERNOON THROUGH
TONIGHT.
MARINE...GLWS IN EFFECT THROUGH TONIGHT. STORM FORCE WINDS
POSSIBLE SUNDAY NIGHT AND MONDAY. HOWEVER...IT IS STILL EARLY.
