Double barrel low pressure systems brought a winter storm to Delaware on the 1st. A combination of snow, sleet and especially freezing rain affected the state mainly during the second half of the day on the 1st. Snowfall amounts were around an inch, but around one quarter of an inch of ice accumulated on exposed surfaces and caused scattered power outages. In addition, the icy precipitation combination caused numerous accidents.
Precipitation started as snow between 9 a.m. and 10 a.m. EST on the 1st throughout most of Delaware. Precipitation changed briefly to sleet in Kent and Sussex Counties and for a more protracted period in New Castle County starting  during the late morning on the 1st. Precipitation changed to all freezing rain in Sussex County around Noon EST, Kent County during the early afternoon and New Castle County by mid afternoon on the 1st. Precipitation changed to plain rain in Sussex County during the early evening on the 1st, but remained freezing rain in the rest of the state until it ended in the middle of the evening on the 1st.
Delaware State police responded to about 130 traffic accidents, 13 with injuries and around 25 disabled vehicles. Delmarva Power reported about 3,900 of its customers lost power because of downed tree limbs and wires in Delaware and Eastern Maryland. The greatest concentration in Delaware was around Felton in Kent County. Many schools had delayed openings on Monday March 2nd, some schools cancelled classes.

Representative ice accumulation included 0.33 inches in Pike Creek (New Castle County), 0.25 inches in Camden (Kent County), Frankford (Sussex County) and Newark (New Castle County) and 0.20 inches at the New Castle County Airport.
Representative snowfall (and sleet) included 1.0 inch in Greenville (New Castle County), 0.8 inches in Frederica (Kent County), 0.6 inches in Felton (Kent County), 0.5 inches in Bridgeville and Seaford (Sussex County) and 0.3 inches at the New Castle County Airport.
The winter storm was caused by the combination of an arctic high pressure system that left plenty of cold air in place near the surface and a low pressure system from the South that pumped precipitation into the region.  At 7 a.m. EST on the 1st, a pair of low pressure systems were in Mississippi and the western Gulf of Mexico off the Texas coast.  During the early afternoon, while the low pressure system moved into the Tennessee Valley,  a new low pressure system was forming off of the South Carolina coast.  The latter low pressure system moved rapidly northeast and was off the New Jersey coast at 7 p.m. EST on the 1st while the latter low pressure system became part of a series of lows along a cold front west of the Appalachians. The coastal low pressure system passed near Nantucket, Massachusetts around Midnight EST on the 2nd. It took most of the associated moisture and precipitation with it as the inland low pressure systems and frontal boundary weakened overnight.
