What happened

The episode as NWS PHI wrote it up.

Freezing rain spread from north to south across the state during the late afternoon and evening on the 9th. Sleet mixed in from time to time. In New Castle County, it changed briefly to snow before ending on the 10th. The precipitation ended from north to south between 3 a.m. EST and 10 a.m. EST on the 10th. Delaware State Police responded to nearly 100 accidents, 11 with injuries as well as 5 disabled vehicles. More than two-thirds of the accidents occurred in Kent County. In Sussex County, the South Rehoboth Boulevard/Coastal Highway was closed because of a jack-knifed tractor trailer. Representative ice accumulations included 0.20 inches in Frankford (Sussex County), 0.06 inches in Milton (Sussex County) and around 0.05 inches at the New Castle County Airport.

The wintry mix of precipitation was caused by the combination of waves of low pressure on a frontal boundary that supplied the moisture and precipitation and an arctic high pressure system to the north of the boundary that supplied the low level cold air. As this boundary sagged southward, the precipitation sagged southward with it. At 7 a.m. EST on the 8th, the high pressure system was centered over James Bay and the frontal boundary across the Lehigh Valley in Pennsylvania. By 7 p.m. EST on the 8th, the frontal boundary moved into New Castle County. By 10 p.m. EST on the 8th, the frontal boundary cleared all of Delaware. At 7 a.m. EST on the 9th, the frontal boundary was located over the lower Delmarva Peninsula with a wave of low pressure forming along it. At 7 p.m. EST on the 9th, the frontal boundary was approaching Cape Hatteras, North Carolina and at 7 a.m. EST on the 10th dropped into northern Florida. At 10 a.m. EST on the 10th, the boundary just passed through Miami, Florida and by then, waves of low pressure were finally too far offshore to affect Delaware.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
356 PM EST MON FEB 9 2015

.SYNOPSIS...
A BROAD AREA OF LOW PRESSURE WILL PASS OFF THE CAROLINA COAST
TONIGHT, WITH HIGH PRESSURE BUILDING OVER THE REGION FROM THE
NORTHWEST FOR TUESDAY AND WEDNESDAY. A COLD FRONT WILL CROSS THE
AREA THURSDAY, WITH A STRONG LOW PRESSURE SYSTEM EXPECTED TO DEVELOP
ALONG THIS FRONT AS IT MOVES OFF THE COAST. VERY COLD AIR AND STRONG
WINDS ARE EXPECTED FOR THE MID-ATLANTIC REGION BEHIND THIS FRONT
THURSDAY NIGHT AND FRIDAY. A CLIPPER SYSTEM MAY EFFECT THE AREA ON
SATURDAY, FOLLOWED BY YET ANOTHER BLAST OF COLD AIR ON SUNDAY AND
MONDAY AS ANOTHER CANADIAN HIGH PRESSURE SYSTEM MOVES EAST.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
ONGOING SYSTEM HAS BEEN SENDING WAVES FOR LIGHT PCPN ACROSS THE AREA
WITH TEMPS MOSTLY AROUND FREEZING IN MOST AREAS AND IN THE 20S
NORTH. MORE PCPN WILL ARRIVE THIS EVENING FROM SOUTH/CENTRAL PA AND
FOR THIS REASON WE WILL KEEP THE WSW ADVISORY FOR THE CENTRAL AREAS.
UP NORTH...LITTLE ADDITIONAL PCPN IS EXPECTED AND WHATEVER OCCURS
WILL PROBABLY BE SNOW. WE WILL KEEP THE ADVISORY FOR THESE AREAS
MAINLY DUE TO ONGOING SLICK CONDITIONS FOR TODAYS PCPN. WE TRIMMED
THE END TIME FOR THE NRN AREAS AT MIDNIGHT. ACROSS THE SOUTH
(DELMARVA AND SE NJ). THE ADV ISSUED EARLIER FOR WHAT APPEARED (AT
THE TIME) AN IMMINENT THREAT FOR FZRA...NEVER REALLY OCCURRED.
BUT...MODELS ARE INDICATING ANOTHER PERIOD OVERNIGHT WHERE MIXED
PCPN AND FZRA POSSIBLE...SO WE WILL KEEP THE ADV IN THESE AREAS
GOING FOR NOW AND PAINT SOME LIGHT FZRA/GLAZE ACCUMS POSSIBLE FOR
THESE AREAS.

LOW TEMPS TONIGHT WILL DROP INTO THE TEENS ACROSS THE FAR
NORTH...AND DROP INTO THE MID/UPPER 20S ELSEWHERE. WINDS WILL BE
MOSTLY N OR NE AT 10 TO 15 MPH OVERNIGHT...HIGHER ALONG THE SHORE
AREAS.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
HIGH PRESSURE WELL TO THE NORTH WILL BEGIN TO BUILD TOWARDS THE
AREA. LOW PRESSURE ASSOCIATED WITH THE SYSTEM FROM THE NEAR TERM
WILL BE WELL TO THE SOUTH...BUT WILL BE STRENGTHENING WHILE MOVING
OFFSHORE. THE ONLY PCPN WE HAVE FOR TUESDAY WILL BE FOR THE MORNING
ACROSS THE DELMARVA AND SE NJ WHERE SLGT CHC OR SMALL CHC POPS WILL
BE FOUND. BY MORNING...TEMPS WILL LIKELY BE COLD ENOUGH FOR MOSTLY
LIGHT SNOW. SKY COVER TUESDAY WILL BE MOSTLY CLOUDY FOR THE MOST
PART...BUT SOME IMPROVEMENTS NORTH ARE POSSIBLE LATER TUE. WINDS
WILL BE MODERATE WITH WINDS MOSTLY NORTHERLY 10 TO 15 MPH AND GUSTS
IN THE LOW 20S MPH RANGE. HIGH TEMPS WILL MOSTLY BE IN THE 30S
ACROSS THE REGION.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
THE MID-LEVEL FLOW PATTERN FROM TUESDAY NIGHT THROUGH MONDAY OF NEXT
WEEK IS FORECAST TO BE PUNCTUATED BY TWO EXTREME TROUGHS...ONE
THURSDAY INTO FRIDAY...THE OTHER LATE SATURDAY THROUGH SUNDAY. SOME
OF THE COLDEST AIR OF THE SEASON...IF NOT THE COLDEST...WILL
INVADE THE NORTHEAST SECTION OF THE COUNTRY IN THEIR WAKE, WITH A
FLOW DIRECTLY FROM THE POLAR REGIONS.

TUESDAY NIGHT SHOULD BE FAIRLY TRANQUIL, WITH LIGHTER WINDS, PERHAPS
SLIGHTLY STRONGER NEAR THE COAST.  NO PRECIPITATION IS EXPECTED, WITH
NORMAL TO SLIGHTLY BELOW NORMAL TEMPERATURES AS SURFACE HIGH
PRESSURE BUILDS OVER THE AREA. WEDNESDAY WILL FEATURE MAINLY CLEAR SKIES
FOR A GOOD PART OF THE DAY, BUT SOME HIGH CLOUDS ARE POSSIBLE IN
THE WEST LATE. HIGH TEMPERATURES ON WEDNESDAY WILL BE SEVERAL
DEGREES BELOW NORMAL. LIGHT SNOW IS POSSIBLE IN THE NORTHERN HALF
OF THE CWA WEDNESDAY NIGHT AS A CLIPPER SYSTEM MOVES THROUGH NEW
YORK STATE. THE COLD FRONT ASSOCIATED WITH THIS SYSTEM WILL MOVE
ACROSS THE AREA ON THURSDAY, USHERING IN BITTER COLD AIR FOR
THURSDAY NIGHT AND FRIDAY. THE ASSOCIATED MID-LEVEL TROUGH IS
EXPECTED TO BECOME NEGATIVELY TILTED JUST AS IT SWINGS THROUGH OUR
AREA THURSDAY NIGHT, SO RAPID DEVELOPMENT OF A SURFACE LOW IS
EXPECTED ONCE AGAIN OVER THE NEW ENGLAND MARITIMES.
UNFORTUNATELY...THE GRADIENT GENERATED BY THIS DEPARTING BUT
DEEPENING LOW PRESSURE SYSTEM WILL BRING GUSTY NORTHWEST WINDS TO
OUR AREA...DRIVING WIND CHILL TEMPERATURES DOWN TO THE NEGATIVE
TEENS (AND PERHAPS BEYOND IN THE HIGHER ELEVATIONS UP NORTH) FOR
THURSDAY NIGHT. HIGH TEMPERATURES ON FRIDAY WILL STRUGGLE TO
EMERGE OUT OF THE SINGLE DIGITS IN THE FAR NORTH, AND WON'T GET
OUT OF THE LOW TO MID 20S IN THE SOUTH...SOME TWENTY DEGREES BELOW
NORMAL FOR THIS TIME OF YEAR. ANOTHER COLD NIGHT IS ON TAP FOR
FRIDAY NIGHT, BUT WITH LESS WIND IT MIGHT NOT FEEL QUITE SO
COLD...AND THE HOUSE WILL BE A LITTLE EASIER TO HEAT.

THEN ANOTHER BLAST HEADS OUR WAY ON SATURDAY, HERALDED BY A CLIPPER
SYSTEM WITH SOME LIGHT SNOW FROM WEST TO EAST STARTING IN THE
AFTERNOON. THIS CLIPPER COULD INTENSIFY AS IT MOVES OFF THE COAST
SATURDAY NIGHT, BRINGING GUSTY WINDS BACK TO THE AREA JUST AS COLD
AIR ONCE AGAIN INVADES THE REGION BEHIND A COLD FRONT. TEMPERATURES
SATURDAY NIGHT AND SUNDAY COULD BE COLDER THAN THE MIDWEEK SYSTEM
AND PERHAPS EVEN COLDER SUNDAY NIGHT GOING INTO MONDAY, BUT BY LATE
SUNDAY WINDS SHOULD BE SUBSIDING JUST A BIT.

ALL-IN-ALL, NOT A VERY NICE WEEK AHEAD...UNLESS YOU/RE A POLAR BEAR!

&&

CONDITIONS LATER TRANSITION BACK TO MIXED PRECIP AND EVENTUALLY
LIGHT SNOW THROUGH THE EVENING TO OVERNIGHT.

WITH REGARDS TO WINDS, NORTHEAST WINDS WILL BECOME MORE
NORTH-NORTHEAST WITH TIME THROUGH TONIGHT, WITH SOME GUSTS TO
