Total Snowfall Accumulation Forecast by 3 AM Thursday:

Timing, Delays, Cancellations:

  • Sleet & Snow mixed will re-develop between 3 and 5 PM and then become heavy, wet snow after 5PM.
  • Heavy snow will continue through the evening before it tapers off  around midnight and ends between 1 and 3AM.
  • Federal Government employees… I am 90% confident of a 2 hour delayed opening Thursday with Unscheduled Leave.

  • The urban heat island of Washington DC and south Arlington will see accumulations of 4 to 6″.
