Snow will develop during the mid morning hours on Sunday. The snow will mix with sleet and change over to freezing rain during the afternoon.

One to two inches of snow is possible in the northern and western suburbs with up to one inch in DC before the change over to sleet and freezing rain.

Freezing Rain will then change over to rain during the evening hours as temperatures slowly rise into the middle 30s. Untreated roadways will be slippery and Winter Weather Advisories will likely be issued.

Potent Storm … Treacherous Commute

Snowfall Potential

Snowfall Potential through Thursday Noon

The options for OPM tomorrow are not easy. The roads will be a nightmare due to the cold temperatures and horrible timing of heavy snow between 4AM and 8AM (the DC Rush hour). A two-hour delay may not serve any purpose because it will still be snowing between 8AM and 10AM.

Snow should taper off and end between 10AM and noon with lingering flurries during the afternoon hours. The best two options for OPM tomorrow (in my humble opinion): Delayed Opening at 11AM or Close the Government.
