Storm Snochi gives way to Friday morning icy spots, and more snow Friday night-Saturday?

*** Capital Weather Gang Live Storm Updates from earlier today ***

** Winter weather advisory until 1 a.m. Friday morning east of D.C./I-95 **

* Snow totals | Zoomable snow total map | Storm news live blog *

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!

From earlier…

  • Energetic upper level disturbance to sweep through D.C. area between roughly 3 and 11 p.m. tonight

  • Snow may be heavy at times, especially between around 6 and 9 p.m. tonight.

SchoolCast:

Many school systems have already decided to close tomorrow and I imagine many of those that haven’t already will.
