Snowfall Totals
Click on the snowfall map below to access more snowfall data from the event.
High pressure over New England supplied cold air to the Mid-Atlantic late Tuesday night into Wednesday morning. Low pressure developing off the Mid-Atlantic coast early Wednesday brought a light wintry mix to the area. Ground temperatures were warm enough for nothing more than a light slushy accumulation from the Washington D.C area southward. The highest snowfall accumulations in the morning were across northern Maryland where temperatures were cold enough and precipitation was heavy enough to receive 2 to 5 inches of snow, causing a slippery morning commute. Precipitation transitioned to light rain and drizzle across most of the area by the late morning through early afternoon as warmer air from the Atlantic wrapped into the system. A strong upper low over the Tennessee Valley Wednesday morning moved through the area during the late afternoon and evening.
Conditions deteriorated rapidly as heavy precipitation overspread the region at the start of the late afternoon rush hour. Colder air moved into the area during this time, allowing precipitation to change quickly to sleet and then heavy snow. There were many reports of thunder and lightning occurring with the sleet and snow. Heavy snow continued through the evening hours with snowfall rates around 2 to 3 inches per hour during the height of the event.
Snowfall totals from the event were highest across the northern and western suburbs of Washington D.C. (see snowfall map). The heavy snowfall coinciding with the afternoon and evening rush hour commute led to hours and hours of gridlocked traffic from treacherous driving conditions. There were countless reports of commuters needing 5 to 10 hours to get home from work while others abandoned their vehicles. The heavy, wet snow brought down many trees and powerlines. The Washington Post reported almost 400,000 people lost power in the D.C. area that evening.

located over the northwestern suburbs of Washington D.C. around 6:45 PM (see first image). An hour later, the band of heavy snow progressed east right over Washington D.C. by 7:45 pm
(see second image).
