** Winter weather advisory until 1 a.m. Friday morning east of D.C./I-95 **
11 p.m. Update: The last of the remaining show showers are diminishing as Storm Snochi exits stage northeast. What’s next? Toward dawn, skies clear and winds diminish, as lows drop back to the mid-to-upper 20s, making for an icy Friday morning as any slush tends to freeze up. Friday we get a break with mostly to partly sunny skies, light winds from the southwest, and highs in the upper 30s to near 40. But then…
…another system could bring a period of snow Friday night into Saturday morning. Right now it looks like a 1-3″ kind of system. That’s not a lock, though. We’ll have more starting at 5 a.m. Thanks as always for joining us!
- Energetic upper level disturbance to sweep through D.C. area between roughly 3 and 11 p.m. tonight
- Precipitation may begin as a mix, but should change over to snow. Thunder is possible.
- Snow may be heavy at times, especially between around 6 and 9 p.m. tonight.
- Accumulations of 1-4 inches possible, and locally higher amounts cannot be ruled out.
- This disturbance has a history of producing very heavy snow: 6″ in 3 hours in Roanoke
Many school systems have already decided to close tomorrow and I imagine many of those that haven’t already will.
3.5 apples: Schools are closed or very likely (90 percent chance or better) will close
3 domes: Greater than 90% chance of unscheduled leave policy and/or delayed opening. 50% or less chance of shutdown.
Update: OPM has announced a 2-hour delay, with option for unscheduled leave/telework
