What happened

The episode as NWS OKX wrote it up.

A cold front slipped south of the tri-state area during the day on Thursday, March 15. This allowed colder air to work into the region after several days of anomalously warm temperatures. Farther to the south, along the Gulf Coast, low pressure developed and deepened as it tracked northeast along the boundary. The deepening low tracked to near the Mid Atlantic coast Friday evening, March 16, to just east of Montauk Point Saturday morning, March 17. |Initially, the precipitation started off as a light mix of snow, sleet, and rain during the early morning hours, but, as the colder air continued to deepen, the preciptation fell primarily as snow during the daytime hours, falling moderate to occasionally heavy at times. During the evening hours, the precipitation changed over to sleet and eventually to freezing rain. |Snow and sleet totals ranged from 6 to 12 inches, with the highest amounts across interior Fairfield and New Haven counties. The NWS Cooperative Observer in Bridgeport measured 6.0 inches.|In addition, there were major impacts on mass transit with high winds and heavy wintry precipitation during the evening rush-hour traffic. Hundreds of flights were cancelled at the metropolitan airports with many planes stuck on the tarmac.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE UPTON NY
1004 PM EDT FRI MAR 15 2007

...MAJOR WINTER STORM TO IMPACT THE TRI-STATE AREA FRIDAY AND FRIDAY
NIGHT...

.NEAR TERM (OVERNIGHT)...
THE POLAR FRONT HAS DROPPED SOUTH OF LONG ISLAND DURING THURSDAY
AFTERNOON WITH GUSTY NORTHERLY WINDS AND LIGHT RAIN IN ITS WAKE. A
DEEP-LAYERED W/SW FLOW ALOFT WILL OVERRUN THE DEEPENING COLD POOL AT
THE SURFACE WITH GENERALLY LIGHT PCPN FALLING OVERNIGHT. WITH HIGH
PRESSURE PUSHING INTO THE REGION FROM THE NORTH DRIER AIR HAS MOVED
INTO PORTIONS OF THE LOWER HUDSON VALLEY ALONG WITH COLDER AIR IN
THE LOWER LEVELS. PRECIPITATION INLAND HAS BECOME MIXED WITH
SLEET...AND FURTHER INLAND PRECIPITATION HAS COME TO AN END. THERE
WILL LIKELY BE A LONG TERM BREAK IN THE STEADY PRECIPITATION INLAND
UNTIL THE LOW PRESSURE SYSTEM DEVELOPING OVER THE SOUTHERN STATES
ADVANCES NORTHWARD FRIDAY MORNING. THIS IS ALREADY REFLECTED IN THE
PROBABILITY GRIDS WITH JUST CHANCES POSSIBLE WELL INLAND UNTIL LATER
FRIDAY MORNING. ONLY CHANGES AT THIS TIME WILL BE TO PRECIPITATION
TYPES INLAND WHERE SLEET HAS MIXED IN. JUST SOME MINOR ADJUSTMENTS
TO THE TEMPERATURES AND DEWPOINTS OVERNIGHT.

MODELS HAVE COME INTO GOOD AGREEMENT WITH TAKING A LARGE SPRAWLING
HIGH PRESSURE SYSTEM ACROSS EASTERN CANADA AND UP INTO THE CANADIAN
MARITIMES BY FRIDAY NIGHT. THIS IN CONJUNCTION WITH LOW PRESSURE
DEVELOPING OVER THE MIDDLE ATLANTIC STATES AND AN AMPLIFYING...
BECOMING NEGATIVELY TILTED UPPER TROUGH OVER THE OHIO VALLEY WILL
PRODUCE A MAJOR LATE SEASON WINTER STORM FOR THE NE. UNLIKE PREVIOUS
STORM SYSTEMS THIS YEAR...A STRONG POLAR HIGH (1040 MB) EXISTS NORTH
OF 40N. HOWEVER...THE TRANSIENT NATURE OF THE HIGH AND A LACK OF AN
UPSTREAM BLOCK OVER THE DAVIS STRAIT WILL PRECLUDE STRONG COLD AIR
DAMMING. THUS...A MARGINAL COLD POOL AND MAJOR CYCLOGENESIS WILL
LIKELY BRING ENOUGH WARM AIR OVER TOP THE COLD LOW-LEVELS TO PRODUCE
A SIGNIFICANT MIXED PCPN EVENT. THUS...THE ISSUANCE OF WINTER STORM
WARNING FOR ALL BUT FAR EASTERN LONG ISLAND AND SOUTHERN NEW LONDON
COUNTY IN CT. THESE LOCATIONS WILL SEE LESSER AMOUNTS OF SNOW AND
ICE AND WILL LIKELY MEET ADVISORY CRITERIA.
&&

.SHORT TERM (FRIDAY THROUGH SUNDAY NIGHT)...
LIGHT PCPN FRI MORNING WILL PICK UP IN INTENSITY BY MIDDAY AS LOW
PRESSURE OVER THE MID ATLANTIC STATES BEGINS TO LIFT NORTHWARD IN
RESPONSE TO AN AMPLIFYING UPPER TROUGH OVER THE OH VALLEY STATES.
THE PCPN WILL BE MAINLY SNOW ACROSS THE FORECAST AREA FROM MID
MORNING THROUGH LATE AFTERNOON WHEN THE COLD AIR WILL BE AT ITS
DEEPEST. SEVERAL INCHES OF SNOW WILL ACCUMULATE BY THE EVENING RUSH
WITH SOME LOCATIONS HAVING RECEIVED 4 TO 8 INCHES BY THIS TIME.

IT IS DURING THE EVENING HOURS THAT WARMER ATLANTIC AIR GETS WRAPPED
INTO THE STORM SYSTEM AND INTO EASTERN SECTIONS OF THE FORECAST
AREA...PRIMARILY ACROSS EASTERN LONG ISLAND AND SE CT. THESE
LOCATIONS WILL LIKELY GO OVER TO PREDOMINANTLY RAIN DURING THE
OVERNIGHT HOURS. TO THE WEST THOUGH...THERE MAY BE JUST ENOUGH WARM
AIR ALOFT TO TRANSITION THE SNOW OVER TO SLEET AND FREEZING RAIN
WITH THE POTENTIAL FOR SIGNIFICANT ICING. AT THIS TIME...IT LOOKS TO
BE MAINLY A SLEET ACCUMULATION VERSUS AN ICE ACCRETION FROM FREEZING
RAIN. THE TRACK OF THE STORM LOOKS TO BE JUST INSIDE THE BENCHMARK
OF 40N...70W. THIS TRACK TYPICALLY DOES NOT SUPPORT AN ALL SNOW
SCENARIO. HOWEVER...THE ISALLOBARIC WIND COMPONENT MAY BE SUCH THAT
THE NORTHERLY LOW LEVEL FLOW KEEPS AREAS CLOSE TO FREEZING. THIS IS
OF GREAT CONCERN SHOULD ENOUGH WARM AIR ALOFT COME IN TO CHANGE THE
PCPN TO RAIN...WHICH COULD RESULT IN A SIG. FREEZING RAIN EVENT.

THE SURFACE LOW TRACKS SOUTH AND EAST OF LONG ISLAND FRI NIGHT TO
APPROX. 100 NM SE OF MTP. THE PCPN ENDS FROM WEST TO EAST SAT
MORNING WITH LITTLE ADDITIONAL PCPN. THE VERTICAL TEMP PROFILE MAY
COOL ENOUGH FOR THE PCPN TO END AS A PERIOD OF LIGHT SNOW ACROSS
EASTERN AREAS SAT MORNING.

TOTAL SNOW AND SLEET ACCUMULATIONS WILL RANGE FROM 8 TO 14 INCHES
NORTH AND WEST OF NYC...TO 5 TO 10 INCHES ALONG THE COAST. THE EAST
END OF LONG ISLAND AND SE CT WILL SEE AMOUNTS OF 4 TO 6 INCHES.
&&

.LONG TERM (MONDAY THROUGH WEDNESDAY)...
A MODERATING TREND ENSUES MON INTO TUE WITH A STRENGTHENING RETURN
FLOW AHEAD OF THE NEXT FRONTAL SYSTEM PROGRESSING ACROSS THE GREAT
LAKES. LOW RAIN CHANCES WILL BE IN THE FORECAST FROM MON NIGHT
THROUGH TUE ALONG AND AHEAD OF THE EASTWARD ADVANCING FRONT.
&&

.HYDROLOGY...
ANOTHER 1/4 INCH OF QPF POSSIBLE TONIGHT BEHIND THE POLAR FRONT WITH
ANOTHER WAVE OF LOW PRESSURE.

HEAVIEST QPF LOOKS TO BE FRI INTO FRI NIGHT WITH OVERRUNNING PCPN
INCREASING IN INTENSITY AS A COASTAL LOW DEVELOPS ALONG THE MID
ATLANTIC REGION AND TRACKS UP THE COAST. AT THIS TIME OVER 2 INCHES
OF QPF MAY BE A POSSIBILITY DURING THIS TIME. THE MAJORITY THIS PCPN
LOOKS TO FALL IN THE FROZEN STATE OVER NYC/NJ/LOWER HUDSON VALLEY
AND INTERIOR CONN. EASTERN LI AND COASTAL SE CONN WILL LIKELY SEE A
CHANGEOVER TO RAIN...WHICH MAY PRESENT THE POTENTIAL FOR SOME URBAN
AND SMALL STREAM FLOODING. AN ADDITIONAL 1 TO 2 INCHES OF RAINFALL
ON TOP OF SEVERAL SLUSHY INCHES OF SNOW WILL LIKELY LEAD TO FLOODING
PROBLEMS. THUS...A FLOOD WATCH HAS BEEN ISSUED FOR NEW LONDON COUNTY
IN CT AND SE/NE SUFFOLK IN NY. THE WATCH TAKES EFFECT AT 00Z SAT AT
WHICH TIMES THESE AREAS WILL LIKELY TRANSITION OVER TO RAIN.

ICE JAMS NOT EXPECTED TO BE A PROBLEM AS OF YET ON OUR RIVERS AND
STREAMS...ESPECIALLY WITH A TURN TOWARDS COLDER CONDITIONS ON
FRIDAY.
&&

.AVIATION...
CEILINGS AND VISIBILITIES HAVE BEEN SLOW TO LOWER EARLY THURSDAY
EVENING. AS COLDER AIR FILTERS IN AND PRECIPITATION MIXES WITH SNOW
AND SLEET CEILINGS AND VISIBILITIES WILL LOWER TO MVFR AND POSSIBLY
IFR...ESPECIALLY AT THE TERMINALS WHERE SNOW WILL BECOME THE
DOMINATE PRECIPITATION. THIS WILL OCCUR FROM THE TERMINALS NORTHWEST
OF NEW YORK CITY EARLIER AND THEN AT THE CITY AND COASTAL
TERMINALS. AT SWF THE PRECIPITATION HAS ENDED AS DRIER AIR HAS
FILTERED IN WITH THE HIGH. PRECIPITATION WILL INCREASE AND BECOME
STEADIER TOWARD MORNING AS THE LOW OVER THE SOUTHERN STATES MOVES
NORTH. BETWEEN 07Z AND 12Z CEILINGS AND VISIBILITIES SHOULD BE IFR
AT ALL THE TERMINALS WITH SNOW AND SLEET. THIS WILL CONTINUE THROUGH
AT LEAST 00Z SATURDAY. THERE COULD BE A PROLONGED PERIOD OF SNOW AND
SLEET ESPECIALLY ALONG THE COAST DURING THE DAY FRIDAY.

WINDS WILL BE FROM THE NORTHEAST THROUGH THE FORECAST
PERIOD...GENERALLY 10 KNOTS OR LESS OVERNIGHT AND THEN INCREASE
TOWARD 12Z AS THE LOW MOVES NORTH. WINDS WILL BECOME GUSTY DURING
THE DAY FRIDAY AND POSSIBLE GUST UP  TO 30 KNOTS AT TIMES.
&&

.MARINE...
NO CHANGES TO THE FORECAST AT THIS TIME.

COLD FRONT HAS JUST ABOUT PASSED THROUGH THE AREA WATERS WITH WINDS
SHIFTING INTO THE NORTH AND NORTHEAST. SEAS CURRENTLY RUNNING AT
AROUND 5 TO 6 FEET. SMALL CRAFT WILL BE CONTINUED TONIGHT ON THE
OCEAN WATERS.

STORM MOVING IN FROM THE SOUTH WILL TIGHTEN THE PRESSURE GRADIENT
OVER THE WATERS TOMORROW AS A HIGH PRESSURE CENTER DRIFTS JUST NORTH
OF NEW ENGLAND. WINDS AND SEAS WILL BUILD. SMALL CRAFT STARTING AT
10Z FOR THE HARBOR AND SOUND STILL LOOKS GOOD. AS THE STORM
APPROACHES FRIDAY NIGHT...A LLJ NEAR 60KT IS PROGGED TO MOVE ACROSS
THE EASTERN WATERS LATE AT NIGHT INTO SATURDAY MORNING. GALE WARNING
THEREFORE WILL REMAIN ON THE OCEAN WATERS STARTING 10Z SAT. COULD BE
A CLOSE CALL FOR THE EASTERN SOUND WITH REGARDS TO GALE WARNING FOR
THE LATE NIGHT FRIDAY AND MORNING HOURS OF SATURDAY...BUT WILL LEAVE
IT AS A SCA FOR NOW. MEANWHILE ON THE OCEAN...SEA/SWELL BUILDS TO 10
TO 13 FEET.

PERHAPS A LULL IN THE ACTION TOWARDS MIDDAY SATURDAY AS THE CENTER
OF THE STORM MOVES JUST EAST OF LONG ISLAND...THEN INCREASING WINDS
BY EVENING ON THE BACKSIDE OF THE STORM. WITH REGARDS THE SCA ON THE
HARBOR AND SOUND...THIS MAY NEED TO BE EXTENDED AT LEAST IN THE
MID-MORNING HOURS OF SATURDAY...BEFORE WINDS DROP FOR SOME TIME WITH
THE PASSAGE OF THE STORM...AND A DECENT CHANCE OF SCA GUSTS SATURDAY
NIGHT ON THE BACK SIDE OF THE STORM. WILL LEAVE SCA AS
IS...CONSIDERING THIS WOULD BE AFFECTING PERIODS 4 AND 5 OF THE
FORECAST. ON THE SAME TRAIN OF THOUGHT...GALES MAY NEED TO BE
EXTENDED ON THE OCEAN WATERS INTO THE MID-MORNING HOURS OF SATURDAY.

AS FOR ANY COASTAL FLOODING CONCERNS...WIDESPREAD MINOR COASTAL
FLOODING EXPECTED DUE TO STRONG NORTHEAST WINDS ACROSS THE WESTERN
LONG ISLAND SOUND DURING THE FRIDAY EVENING HIGH TIDE CYCLE. THE
STORM SURGE FORECAST TO BE 2 1/2 TO 3 FT AT THE TIME OF HIGH TIDE.
ELSEWHERE...THE SURGE IS FORECAST TO REACH SLIGHTLY BELOW WIDESPREAD
MINOR FLOODING LEVELS. NEXT HIGH TIDE IS SATURDAY MORNING. WILL LET
LATER SHIFTS ASSESS THE POTENTIAL OF COASTAL FLOODING DURING THAT
TIME...AS IT IS IN THE 4TH PERIOD OF THE FORECAST.

AN OFFSHORE FLOW WILL GRADUALLY WEAKEN ON SUNDAY AND BECOME WESTERLY
ON MONDAY. SEAS WILL GRADUALLY SUBSIDE AS WELL.
