Looking to our west, Pittsburgh upped snowfall totals along the MD/PA line. Seems like this system is rather energetic, and I would argue it bodes well for us later on tonight.
According to my records, since moving back to Maryland in August of 2016, I haven't experienced a December snowfall greater than 3.4", or an overall snowfall of greater than 4.8". Let's see what happens tonight!
Based off mesonet data, the wet bulb temp is 32/33 degrees for everyone west of I-95. It won't take much to bump this down below more once things get started. It looks like we might waste very little, if anything at all, on getting all frozen.
Ceilometer from McMillan Reservoir in DC showing a steady decrease in cloud heights. Precip is definitely starting to work towards the ground everywhere.

Agreed. Unlike other events, we have cold ground at night, and there's a fresh press of legit continental polar air coming in. The Bittinger mesonet site is already down to 27°, and the Frostburg site is down to 28°.
12z GFS now has a surface low off the Jersey coast, which allows precip to fill in better. Looks like 0.5" QPF line bumps back from Delaware to the Harford/Cecil County line.
3:30 pm was when Mt. Holly would push their products. You always wanted to see the crawl on the lower third go "...WINTER STORM WARNING FOR THE GREATER DELAWARE VALLEY..." Pure magic.
