What happened

The episode as NWS PHI wrote it up.

Snow in New Castle County and a wintry mix in Kent and Sussex Counties during the morning of the 18th caused slippery and hazardous traveling conditions on untreated roadways. Delaware State Police responded to approximately 65 accidents, 14 of them with injuries as well as about 25 disabled vehicles. Most of the disabled vehicles were vehicles that skidded off of roadways. The majority of the accidents were in Kent and New Castle Counties, but the majority of the injuries were in Sussex County. Snowfall averaged 1 to 2 inches in Kent and New Castle Counties and less than one inch in Sussex County. Ice accumulations were less than one tenth of an inch in Kent and Sussex Counties. Many school districts had delayed openings as did the city of Wilmington.

In New Castle County, snow fell between 2 a.m. and 7 a.m. EST on the 18th. In Kent and Sussex Counties, the snow started around 2 a.m. EST on the 18th also, but changed briefly to sleet and then freezing rain between 5 a.m. EST and 6 a.m. EST that morning. Precipitation transitioned to plain rain around 6 a.m. EST in Sussex County, but continued to fall as freezing rain in Kent County until it ended around 730 a.m. EST on the 18th.

Representative snowfall totals included 2.3 inches in Talleyville (New Castle County), 2.0 inches at the New Castle County Airport, Newport and Newark (New Castle County), 1.8 inches in Glasgow (New Castle County), 1.6 inches in Dover (Kent County) and 0.5 inches in Bridgeville and Ellendale in Sussex County.

The snow was caused by an occluded front that moved into West Virginia during the early morning of the 18th. A new low pressure system formed on a warm front over the Delmarva Peninsula around sunrise on the 18th and then tracked northeast reaching the central New Jersey coast in the middle of the morning.

What forecasters said that day

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 Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Feb 18, 12:36 AM EST, 1 hour 24 minutes earlier.

Area forecast discussion, Feb 18, 12:36 AM EST, 1 hour 24 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1236 AM EST TUE FEB 18 2014

.SYNOPSIS...
LOW PRESSURE MOVING NORTHEAST FROM THE OHIO VALLEY WILL REDEVELOP
ALONG THE NEW JERSEY COAST TUESDAY MORNING THEN RACE OUT TO NOVA
SCOTIA TUESDAY NIGHT. THEN THE THE MAIN WEATHER STORY THE REST OF
THIS WEEK WILL BE MILDER WEATHER AND A SERIES OF FRONTS. A COLD
FRONT WILL CROSS THE MID ATLANTIC STATES MIDDAY WEDNESDAY. A WARM
FRONT IS EXPECTED TO ARRIVE THURSDAY NIGHT...BUT THE WARM UP WILL
BE SHORT LIVED AS IT WILL BE IMMEDIATELY FOLLOWED BY A STRONG COLD
FRONT LATE FRIDAY. ANOTHER COLD FRONT MAY CROSS OUR AREA THIS
WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE MAIN SNOW BAND IS CROSSING CENTRAL PA NOW. BASED ON THE RADAR
TRENDS...IT SHOULD BE ARRIVING IN THE WESTERN PORTIONS OF THE
REGION WITHIN THE HOUR. THIS SNOW BAND WILL IMPACT LOCATIONS FOR 2
TO 3 HOURS...MEANING MOST OF THE HEAVY SNOW SHOULD BE DONE WELL
BEFORE THE RUSH HOUR. THERE ARE SOME LIGHT SNOW SHOWERS BEHIND THE
MAIN BAND...BUT WITH CLOUD TOPS ALREADY WARMER THAN -8 C AND
CONTINUING TO WARM...THE UPPER LEVEL LOW ALREADY OCCLUDING...DO
NOT EXPECT MUCH ADDITIONAL SNOW ONCE THE BAND GOES THROUGH. THIS
IS ALSO IN LINE WITH THE HRRR...SHOWING LITTLE REDEVELOPMENT
OF PRECIPITATION UNTIL THE MAIN AREA OF LIFT IS GENERALLY NE OF
OUR REGION. STILL...2 TO 4 INCHES IS POSSIBLE UNDER THE BAND. HAVE
LOWERED FORECAST SNOW TOTALS SLIGHTLY TO ACCOUNT FOR THIS
INCREASINGLY BRIEF WINDOW OF OPPORTUNITY FOR ANY HEAVY SNOW...BUT
THE WINTER WEATHER ADVISORY STILL LOOKS IN GOOD SHAPE. WILL
REEVALUATE AFTER THE SNOW BAND MOVES THROUGH THE REGION.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TODAY/...
MADE A FEW CHANGES TO THE GRIDS THIS EVENING FOR THIS SHORT TERM
PERIOD. PER THE FORECAST SOUNDINGS, WE TOOK OUT THE MENTION OF
RAIN FOR BERKS COUNTY, THE LEHIGH VALLEY, AND NORTHWEST NEW
JERSEY. WE ALSO SPED UP THE BACK END OF THE PRECIPITATION AROUND
MIDDAY HAVING IT COME TO END A COUPLE HOURS SOONER FOR OUR CENTRAL
AND SOUTHERN ZONES.

WITH THE SOUNDINGS SHOWING SOME DRYING ALOFT TOWARD THE END OF
THE EVENT, WE MIGHT SEE SOME DRIZZLE. BUT WHEN THIS OCCURS (IF IT
OCCURS), TEMPERATURES SHOULD BE ABOVE FREEZING. SO WE DIDN'T
ADJUST THE FREEZING RAIN IN THE GRIDS.

PREVIOUS...WE EXPECT PRECIPITATION TO BE ONGOING TUESDAY MORNING,
WITH SNOWFALL CONTINUING TO ACCUMULATE WHERE IT FALLS. AS WE
PROGRESS THROUGH THE MORNING, THE FRONTAL BOUNDARY IS EXPECTED TO
PUSH THROUGH THE AREA, WHILE A TRIPLE POINT/COASTAL LOW DEVELOPS
AND TAKES OVER AS THE DOMINANT LOW WITH THE SYSTEM. AS THE LOW AND
FRONT PUSH THROUGH AND LIFT TO OUR NORTH, TEMPERATURES WILL
CONTINUE TO RISE THROUGH THE DAY. AS THE TEMPERATURES RISE,
SNOWFALL WILL BEGIN TO TRANSITION OVER, AND MIX WITH OR CHANGE TO
RAIN WHERE IT FALLS FROM SOUTH TO NORTH. THERE IS THE POSSIBILITY
FOR A BRIEF PERIOD OF FREEZING RAIN TO OCCUR FOR AREAS WHERE THE
TRANSITION BEGINS THE EARLIEST, I.E. THE SOUTHERN TIER OF COUNTIES
IN THE ADVISORY. THIS IS EXPECTED TO BE BRIEF AT THE ONSET OF THE
TRANSITION PERIOD, BEFORE CHANGING TO ALL RAIN FOR THE SOUTHERN
AREAS. AREAS FARTHEST NORTH WILL LIKELY REMAIN ALL SNOW BEFORE
PRECIPITATION ENDS, HENCE HIGHER SNOWFALL AMOUNTS UP NORTH. WE
EXPECT ALL PRECIPITATION TO COME TO AN END DURING THE AFTERNOON,
WITH TEMPERATURES WARMING 5 TO 10 DEGREES WARMER THAN MONDAY AND
NEARLY EVERYONE RISING ABOVE FREEZING.

&&

.LONG TERM /TONIGHT THROUGH MONDAY/...
500 MB: ANOTHER STRONG SHORT WAVE PASSAGE WEDNESDAY THROUGH THE
NORTHEAST UNITED STATES IS FOLLOWED BY STRONG RIDGING ALOFT INTO
FRIDAY AS THE MEAN TROUGH SHIFTS WESTWARD AND BECOMES POSITIVELY
TILTED THIS WEEKEND...AXISED FROM HUDSON BAY TO THE SOUTHERN
PLAINS. THIS PATTERN PRODUCES A SIGNIFICANT WARMING TREND HERE
LATE THIS WEEK.

TEMPERATURES: TUESDAY NIGHT THROUGH THURSDAY NEAR OR SLIGHTLY ABOVE
NORMAL... THEN THE CALENDAR DAY AVERAGE ON FRIDAY...10 TO 15 DEGREES
ABOVE NORMAL...COOLING TO ABOUT 5 DEGREES ABOVE NORMAL SATURDAY...AND
WITHIN SEVERAL DEGREES OF NORMAL SUNDAY THROUGH MONDAY.

FORECAST BASIS...12Z/17 BLENDED NCEP MOS TUE NIGHT-THURSDAY THEN WPC
1523Z/17 GUIDANCE THURSDAY NIGHT THROUGH MONDAY WAS GRIDDED-POSTED
BASICALLY AS IS.

TUESDAY NIGHT...MOSTLY CLEAR.  PATCHY FROSTY FOG POSSIBLE LATE?

WEDNESDAY...A MIDDAY CFP MAY BE ACCOMPANIED BY SHOWERS...SW WIND
GUST 15-25 MPH IN THE MORNING SHIFTING TO NORTHWEST DURING THE
AFTERNOON.

WEDNESDAY NIGHT...MOSTLY CLEAR. PATCHY FROSTY FOG LATE IN THE
COUNTRYSIDE.  LIGHT WIND.

THURSDAY...CONSIDERABLE CIRRUS WITH LIMITED SUNSHINE. CHILLING
COASTAL GRADIENT ONSHORE FLOW OFF THE WATER WHERE THE SEA SURFACE
TEMPS ARE IN THE 30S!

THURSDAY NIGHT...AREAS OF RAIN AND DRIZZLE WITH STRATUS AND FOG
AS DEWPOINTS WARM ABOVE FREEZING ON SOUTHERLY FLOW OVER THE DEEP
SNOW PACK FROM NORTHEAST MARYLAND THROUGH NORTHERN DELAWARE AND
THE NW 2/3RDS OF NJ NORTHWARD. COULD HAVE DENSE FOG. THE
STRENGTHENING BOUNDARY LAYER WIND MAY BE INVERSION LIMITED ON
MIXING DOWN MUCH WIND DURING THE NIGHT FAVORING LOW LVL WIND
SHEAR.

FRIDAY...SHOWERS AND POSSIBLE TSTMS AHEAD OF A COLD FRONT WITH
POTENTIAL WIND ADVISORY CRITERIA 45 MPH GUSTS AND IF THUNDER...
POTENTIAL FOR SVR IN NJ/DE WITH 60 TO 70 KT OF WIND FROM 850-700
MB. CLEARING LATE. MLCAPE RIGHT NOW IS MODELED UNDER 300J...
MAINLY DELAWARE.

A QUESTION THIS DAY WILL BE WHAT TIME THE COLD FRONT WILL ARRIVE.
AT THIS TIME...EXPECT THE FRONT TO SWEEP THROUGH THE REGION
FRIDAY AFTERNOON. WHAT THIS TIMING WILL MEAN FOR THE REGIONS
WEATHER IS THAT THERE WILL LIKELY BE A LARGE MAX TEMPERATURE
GRADIENT ACROSS THE REGION...WITH HIGHS POSSIBLY ONLY IN THE 40S
LEHIGH VALLEY NORTHWARD THROUGH NW NJ AND THE POCONOS TO THE 60S
IN SOUTHERN DE.

GRADIENT WIND SW GUSTY 35-45 MPH MIDDAY SHIFTS NW BY EVENING WITH NW
GUSTS TO 20 MPH AT NIGHT.

NEXT WEEKEND...AN UPPER LEVEL SHORT WAVE TROUGH SHOULD CROSS THE
MID ATLANTIC STATES...THOUGH THERE WERE SIGNIFICANT DIFFERENCES
BETWEEN THE GFS AND ECMWF ON THE TIMING AND AMPLITUDE OF THIS
TROUGH. BREAKING IT DOWN AS OF OUR 2030Z/17 FCST...OUR
INTERPRETATION...

SATURDAY...DRY AND NICE.  W WIND GUST 15 MPH.

SUNDAY AND MONDAY...WPC GUIDANCE.

&&

.AVIATION /05Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

THE MAIN SNOW BAND IS IN CENTRAL PA NOW...LIFTING RAPIDLY ENE TO
THE REGION. UNDER THIS SNOW BAND...EXPECT THE BULK OF THE SNOW TO
OCCUR. IN ADDITION...IFR CONDITIONS ARE LIKELY. A FEW SITES IN
BOTH MD AND PA HAVE REPORTED VISIBILITIES AS LOW AS 1/4SM WITH THE
SNOW BAND. BUT GIVEN THE ISOLATED NATURE OF THOSE
REPORTS...CONFIDENCE IS LOW THAT ANY TERMINAL IN OUR ARE WILL SEE
CONDITIONS THAT LOW. THUS HAVE KEPT EVERYONE ABOVE AIRFIELD
MINIMUMS FOR NOW.

THE MAIN SNOW BAND SHOULD BE THROUGH OUR AREA BY 12Z. BEHIND
IT...EXPECT ANOTHER PERIOD...AROUND 6 HOURS...OF LOW
CLOUDS...GENERALLY IN MVFR RANGE. SOME LIGHT DZ OR FZDZ IS ALSO
POSSIBLE...BUT CONFIDENCE IS NOT HIGH ENOUGH TO INCLUDE IN THE TAF
FOR NOW. HIGH RES MODELS SHOW SOME REDEVELOPMENT OF MOSTLY RAIN POSSIBLE
ALONG THE JERSEY SHORE AFTER 15Z...BUT AT THIS TIME IT LOOKS TO
STAY MOSTLY N OF KACY.

OUTLOOK...
TUESDAY NIGHT...VFR. DIMINISHING WESTERLY WIND WITH GUSTS UNDER 20
KT TURNING LIGHT SW LATE.

WEDNESDAY...GENERALLY VFR CONDITIONS EXPECTED. ISOLATED MVFR CONDITIONS
POSSIBLE IN SHRA...MAINLY IN THE MORNING. SLIGHT CHANCE OF FREEZING
RAIN SHOWERS E PA IF IT DEVELOPS SOON AFTER DAYBREAK. SW WIND
GUST 20-30 KT SHIFT NW DURING THE AFTERNOON.

WEDNESDAY NIGHT...VFR WITH PATCHY IFR FROSTY FOG POSSIBLE TOWARD
SUNRISE THURSDAY IN THE COUNTRYSIDE.

THURSDAY...GENERALLY VFR THROUGH THE DAY. CONDITIONS DETERIORATING
TO IFR IN ST/FOG/RAIN-DRIZZLE THURSDAY NIGHT. LLWS POSSIBLE BY
DAYBREAK FRIDAY.

FRIDAY...MVFR...AND POSSIBLY IFR IN ST/FOG/SHOWERS EXPECTED ACROSS
THE REGION IN THE MORNING. COLD FRONT MOVES THROUGH FRIDAY AFTERNOON...
BRINGING AN ABRUPT WIND SHIFT...BUT ALSO IMPROVING CONDITIONS.
LLWS POTENTIAL DURING THE MORNING. SW WIND GUSTS 30-40 KT THROUGH
MIDDAY SHIFT NW AFTER THE CFP. SMALL CHC OF A COLD FRONTAL PASSAGE
TSTM...ESPECIALLY KMIV AND KACY.

SATURDAY...VFR.

&&

.MARINE...
SUB-ADVISORY WINDS EARLY IN THE PERIOD AS HIGH PRESSURE PUSHES
OFFSHORE THEN OUT TO SEA. HOWEVER, SMALL CRAFT ADVISORY WINDS ARE
EXPECTED TO INCREASE OVERNIGHT AS A FRONTAL BOUNDARY APPROACHES THE
AREA. WINDS MAY BRIEFLY DROP BELOW ADVISORY LEVELS EARLY DURING THE
DAY, BEFORE INCREASING LATER IN THE AFTERNOON. IT IS POSSIBLE THAT
WINDS COULD APPROACH GALE FORCE BRIEFLY AROUND DAYBREAK TUESDAY, BUT
IT SHOULD NOT BE LONG ENOUGH OF A DURATION TO WARRANT A WARNING.

OUTLOOK...
TUESDAY NIGHT...AFTER 10 PM...NO HEADLINE ANTICIPATED.

WEDNESDAY...SCA CONDITIONS POSSIBLE WITH SOUTHWESTERLY FLOW
TURNING WESTERLY THROUGH THE DAY.

THURSDAY...SUB-SCA CONDITIONS THROUGH THE DAY...BUT WINDS AND WAVE
HEIGHTS INCREASE THURSDAY NIGHT WITH PROBABLE SCA CONDITIONS.

FRIDAY...SCA OR POSSIBLY MARGINAL GALE CONDITIONS. WINDS WILL BE
SOUTHERLY IN THE MORNING...THEN TAKING AN ABRUPT SHIFT TO NORTHWESTERLY
IN THE AFTERNOON. THE INVERSION WITH 50S DEWPOINTS OVER SSTS OF 30S
IS A BIG FACTOR IN HOW MUCH WIND TRANSLATES TO THE MARINE SFC.

SATURDAY...NO HEADLINE ANTICIPATED AT THIS TIME.
