Strange thing today. I was working down near AFB today. This morning that area had a good burst of snow. Probably nearly 3" in grassy areas. The sun came out about 12:45. By 2:30 most of the snow was gone. I'm driving home on route 50. Suddenly I notice snow on all the trees and ground as I near bowie. I get to my house just east of crofton and there's snow everywhere. Probably 2" on grassy areas. Snow didn't melt at all. Strange..

High ratio snow looks to be in the cards tonight. H85 temperatures seem to be near perfect and in correlation with the DGZ. Looking like 850's near -12 over BWI, which could lead to 15-18:1 ratios despite surface temperatures around 28-30. The result could be 2" in a more spread out area with lollies to 3" once again.

Me too. My wife measured 1.3" at home in Clarksburg but her "measurements" leave a little something to be desired when it comes to process.

Any other Clarksburg obs would be appreciated.

Measured 1.5" downtown at 18th and F, NW.

. I measured 1.5" on flagstone patio surface.

yup...love the 0.25" that tickles DC and Baltimore

This one has more potential than last nights. Hi-res models were putting out .1-.15 for this AM's event. Congrats on today btw, and think you could be celebrating tomorrow again. I think I get in on this one as well, only .7" this AM but a beautiful snow nevertheless. 

 

RAP has been juicing up each run, great sign.
