Was just about to post that. It does look like there's a change back to snow trying to occur. Also that's right where the leading edge of the 850/925 temps go back below freezing.
Yup. I know it's only a matter of an hour at most, but this is amazing. Since moving back to Maryland in August 2016, the most snow I've seen is 5" in one event.
For perspective, the average December snowfall at IAD, DCA, and BWI is: 3.5", 3.0", and 2.3" respectively. A lot of folks are going to get their December average snowfall in under 6 hours and there's still two weeks left in the month.
Sterling WFO is releasing a special 18z balloon. It'll be worth checking when it's posted on SPC's page, especially for the lower Susquehanna Valley crew that's worried about mixing.
It's snowing a solid clip in Reisterstown. So long as it's not washed away this evening I'll be happy. Snow on Christmas decorations is like double secret bonus snow.
