A low pressure system that traversed across the southern United States brought heavy snow to Delaware on the 16th and 17th.  Snowfall averaged 3 to 8 inches with the highest amounts in the southern half of the state. The snow fell through the morning commute on the 17th and coupled with below freezing temperatures made for very hazardous travel on untreated and less traveled roadways.
The snow began across Delaware between 6 p.m. EDT and 8 p.m. EDT on the 16th. The snow fell at its heaviest between Midnight EDT and 6 a.m. EDT on the 17th, tapered off during the afternoon of the 17th and ended from north to south between 2 p.m. EDT and 7 p.m. EDT on the 17th. Delaware State Police responded to about 110 traffic accidents (14 with injuries) and assisted nearly 70 disabled vehicles. There were six traffic accidents with injuries in Sussex County, five in New Castle County and four in Kent County. A couple of the more serious accidents included a plow truck that overturned on interstate 95 in New Castle County, a car and train that collided in Ellendale in Sussex County and a vehicle that struck a tree in Harrington (Kent County). Court Houses and Delaware State Offices were closed in Kent and Sussex Counties. All schools were closed. There were municipal and school delayed openings on the 18th.

Representative snowfall included 8.1 inches in Harrington (Kent County), 7.4 inches in Selbyville (Sussex County), 7.0 inches in Stockley and Ellendale (Sussex County), 6.9 inches in Georgetown (Sussex County), 6.4 inches in Viola (Kent County), 5.7 inches in Dover (Kent County) and Laurel (Sussex County), 5.0 inches in Glasgow (New Castle County), 4.7 inches in Bridgeville (Sussex County), 4.1 inches in Townsend (New Castle County), 3.9 inches in New Castle (New Castle County), 3.3 inches in Talley (New Castle County) and 2.5 inches at the New Castle County Airport.
The snow was caused by a pair of low pressure systems that moved across the southern part of the United States. On the morning the 16th the primary low pressure system was located over Arkansas. It moved east and at 8 p.m. EDT was located over northern Alabama. Very early on the 17th, a secondary low pressure system started forming near Wilmington, North Carolina as the primary low pressure system reached Atlanta, Georgia. While the secondary low pressure system moved offshore during the day on the 17th, the original (primary) low pressure system was slowly suppressed south as a high pressure system built into New York State.  This ended the snow across Delaware.
This was the last event in which an inch or more of snow fell at the New Castle County Airport near Wilmington. The entire seasonal snowfall total at the airport was 56.1 inches and was the second snowiest season on record to the 72.8 inches of snow that fell during the 2009-10 season.
