Monday Jan 9 – This quick update is about a small band of precipitation that will try to arrive with a mid level warm front (at cloud level). The timing of this piece of energy will be in the morning, after sunrise. The surface temperatures will still be well below freezing. But, warming will be taking place at cloud level that could allow for some sleet or freezing drizzle. This will be the beginning of the warm up this week.
Typical this type of set up will cross the mountains and dry up east of Hagerstown. But there is enough support that ‘something’ might survive. If anything I would suggest the best chance would be along and north of I-70 to the PA line and into Pennsylvania. So, I figured I had to mention it. But I don’t want to scare you or over hope your hopes for a delay.
This band will be light and the timing will be after sunrise. But at this point, the potential error in track and timing should open the window for a 30% to 40% chance of something reaching central Maryland. I will be up early to give another update to help you plan should this turn into anything. Here is what my trusty High Resolution Rapid Refresh Model is showing.

Notice how the moisture falls apart east of Hagerstown…
