What happened

The episode as NWS ALY wrote it up.

Low pressure developed over the lower Mississippi Valley on Saturday April 14th, and then moved northeast while intensifying, reaching the southern Appalachians by Sunday morning, April 15th, and then just south of western Long Island by Monday morning, April 16th. This low became very intense, with a central barometric pressure falling below 970 millibars upon reaching just south of Long Island Monday morning. The low then headed off the New England coast by Tuesday morning.| |This intense coastal storm spread heavy precipitation across western Massachusetts, starting on Sunday, and persisting into late Monday. Initially, the precipitation fell as a mixture of wet snow, sleet and rain, with snow and sleet more prevalent across the higher elevations. The precipitation then changed to plain rain by Monday morning. Liquid equivalent precipitation total from this storm ranged from 3 to 6 inches. This led to minor flooding across portions of western Massachusetts Monday afternoon into early Tuesday.

NATIONAL WEATHER SERVICE ALBANY NY
447 AM EDT MON APR 16 2007

.SYNOPSIS...
A POWERFUL STORM IS CENTERED NEAR NEW YORK CITY...AND WILL SLOW
DOWN ITS MOVEMENT BEFORE DRIFTING SLOWLY SOUTHEAST AND OUT TO SEA
ON TUESDAY. THE UPPER PORTION OF THE STORM WILL REMAIN OVER OUR

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
PRECIPITATION TYPE IS STILL LARGELY ELEVATION DEPENDANT...ALTHOUGH
WARMER AIR FROM THE SURFACE THROUGH THE BOUNDARY LAYER IS STILL
WORKING WESTWARD BASED ON 00Z AND 06Z AREA SOUNDINGS. DECENT
CONSENSUS FROM MOST SOURCES OF OPERATIONAL AND ENSEMBLE GUIDANCE
SUGGEST LOW LEVELS WARM ENOUGH TO SUPPORT MOSTLY RAIN TODAY FROM
SOUTHERN VT THROUGH THE BERKSHIRES...NW CT AND MUCH OF EASTERN NEW
YORK ALONG THE HUDSON RIVER...INCLUDING MOST OF THE CAPITAL
DISTRICT. SOME LIGHTNING STRIKES INDICATED OVER NJ...PA AND
SOUTHERN NY...BUT KEEPING THUNDER OUT OF OUR FORECAST SINCE ANY

KEEPING WIND ADVISORY IN HIGHER ELEVATIONS OF SOUTHERN
VT AND BERKSHIRES...AND AREAS OF EASTERN NY NEAR THE VT/MA
BORDER...THROUGH 9 AM...WHEN WINDS WILL DIMINISH ENOUGH TO LET
ADVISORY EXPIRE. WINTER STORM WARNINGS AND WINTER WEATHER
ADVISORIES WILL BE CANCELLED ALONG AND EAST OF THE HUDSON
RIVER...BUT ELEVATIONS ABOVE 1500 FEET WILL CONTINUE TO SEE ENOUGH
SNOW...WITHIN THE MIX WITH RAIN AND SLEET...TO KEEP WARNINGS
UP. THIS INCLUDES ADIRONDACKS TO NORTHERN SARATOGA...AND PEAKS OF
THE CATSKILLS. KEPT WESTERN MOHAWK VALLEY AREAS IN
WARNING...ALTHOUGH AREAS RIGHT ALONG THE RIVER WILL SEE MOSTLY
RAIN. ABRUPT CHANGES IN ELEVATION IN SHORT DISTANCES MEANS
BROAD BRUSHING THE TEXT...SO THE WARNINGS AGAIN ARE FOR HIGHER

>5SD V ANOMALY IN SAME STORM...ALONG WITH PWAT ANOMALIES NEAR 3 SD
ABOVE NORMAL. 250 MB WIND ANOMALIES -3SD CONTINUES TO SUGGEST
VERY SLOW MOVING UPPER LOW. SURFACE LOW AROUND 4SD BELOW NORMAL.
SOME PEAKS IN THE ADIRONDACKS MAY SEE SNOW TOTALS UP TO 2 FEET.
SOME RAINFALL TOTALS THROUGH TUESDAY WILL BE ABOVE 8 IN SOUTHERN
AND EASTERN AREAS. IMPRESSIVE STORM FOR MID APRIL...WILL LOOK FOR

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
BY THIS EVENING...COOLING WILL TAKE PLACE AT THE BOUNDARY LAYER
FROM WEST TO EAST...AND AREAS SEEING MOSTLY RAIN WILL SEE MIXING
WITH AND OCCASIONALLY CHANGING TO PERIODS OF SNOW SHOWERS. DECENT
CONSENSUS IN ALL OPERATIONAL AND ENSEMBLE GUIDANCE SOURCES THAT
THERE WILL BE A DECREASE IN THE COVERAGE OF RAIN/SNOW SHOWERS MOST
OF TUESDAY...THEN ONE MORE PIECE OF UPPER ENERGY ROTATES AROUND
THE PERIPHERY OF THE UPPER LOW...AND TRACKS WEST INTO MAINLY
EASTERN AREAS LATE TUESDAY AFTERNOON AND EVENING...WITH MORE RAIN
AND SNOW CHANCES. SO...LOWERED TO CHANCES TUESDAY...THEN BACK UP
TO LIKELY LATE TUESDAY AFTERNOON AND EVENING. BASED ON SURFACE
TEMPERATURES...MIX OF RAIN AND SNOW SHOWERS IN VALLEYS ONCE AGAIN.
BY WEDNESDAY...ONE PRIMARY UPPER LOW GRADUALLY TRACKS OUT TO
SEA...BUT STILL LINGERING MOISTURE AND CLOUD COVER...WITH
BROAD...WEAK UPPER TROUGH AXIS AND UPPER DEFORMATION OVER THE
REGION...AND VERY WEAK HIGH PRESSURE DISPLACED WELL TO THE
NORTHWEST SLOWLY BUILDING IN. CLOUD COVER AND SPRINKLES/FLURRIES
WILL STILL BE AROUND WEDNESDAY...ESPECIALLY WITH EASTERLY BOUNDARY
LAYER WINDS. TEMPERATURES IN 40S TUESDAY AND WEDNESDAY...COOLER IN
MOUNTAINS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
BROAD...WEAK UPPER DEFORMATION AREA PERSISTS OVER OUR
REGION...WITH ADDITIONAL WEAK UPPER LOWS TRACKING SOUTH OF OUR
REGION...SO LOOKS MOSTLY CLOUDY WITH SOME CHANCES FOR SHOWERS AND
SNOWSHOWERS WELL INTO THE EXTENDED WITH BELOW NORMAL TEMPERATURES.

&&

.AVIATION /08Z MONDAY THROUGH FRIDAY/...
WIDESPREAD PRECIPITATION CONTINUES ACROSS AREA WITH RAIN AT TAFS
SITES AND EASTWARD WITH SNOW AND SLEET TO THE WEST ESPECIALLY

MORNING. THE MODELS INDICATE LOW WILL BASICALLY STALL THERE
TODAY...THEN HEAD EASTWARD TONIGHT. THUS...THE PRECIPITATION WILL
CONTINUE TODAY POSSIBLY INTO THIS EVENING THEN TAPER OFF. STRONG
AND GUSTY EASTERLY WINDS THIS MORNING WILL WEAKEN SOME AS WE HEAD
INTO THE AFTERNOON HOURS AND EVEN MORE SO THIS EVENING. OVERALL
MVFR-IFR CONDITIONS WILL IMPROVE MVFR TO POSSIBLY VFR AT TIMES
TONIGHT. SKIES WILL REMAIN OVERCAST THROUGH PERIOD.
