Been sitting on a plane for 3 hours now. 

Loudoun government closed. 

Drive from Frederick to DCA was fun. Roads caved quickly. Hoping flight stays on time. 

Frederick MD schools closed tomorrow. 

Frederick County Md schools closed tomorrow. 

What is the chance my 6am flight out of DCA is impacted?

Pre-dawn Friday as it stands now. 

Thanks. Have a 6:05 flight out of DCA so hoping for no delays getting out of town. 

What’s the potential start time looking like at DCA?

Snow picking up again and flake size increasing. 

Very fine flakes here in Frederick. 

This band in Frederick means business

3-6” is a solid bar right now. We are over 2” currently and the good stuff is really just starting. NAM has been steady 4.5-6” for several runs. Sounds right for what’s transpiring. You in North FDK? 

Sounds good to me. Yeah, right on the other side of the Rt. 15 bridge. North crossing/willowbrook near the sheetz.

Was noticing this as well. The evolution is going as expected from what has been depicted by most guidance. Should see some 5-7” totals out of this one at this rate. Combo of 85H frontogen coupled with the mid-level ascent pattern should yield periods of 0.75-1.5”/hr rates for a time overnight into the early morning hrs. 

Where do you feel like we end up? Just down the road from you. 

I have a flight at 6 am the 20th from DCA so bank on the GFS. 

Seems like mostly snow in Frederick now. 

Just started in Frederick. Mostly sleet

Snow has switched to sleet here.
