watching potential for more snow friday night into saturday morning

Now that Tuesdays storm is gone, let’s look to the Friday and Saturday timeframe. A clipper system on Thursday will provide a fresh shot of cold air, with lows overnight Thursday and Friday night in the upper 20s to low 30s.

A second clipper, possibly a bit stronger, will arrive overnight Friday into Saturday morning. It appears that we will be cold enough to support snow in our area, as temps during this time will be between 29 and 33 degrees. But the track is uncertain, and that will determine how much moisture is available to produce snow.
There are 2 possible scenarios, and we describe them below:
​
SCENARIO 1: The clipper is stronger and further north, leading to a large swath of snow across the mid Atlantic. Within this swath, a more narrow area of snow could accumulate to a few inches especially across central and northern MD where temps are colder. At this point, I would give this a 50% chance of occurring.

SCENARIO 2: The clipper is weaker and further south. So while we still would likely see some snow falling, there would certainly be less in the way of accumulation, with anything meaningful staying to our south across central VA. We would be cold, but there wouldn’t be much moisture to work with. I would give this a 40% chance of occurring. ​

Now I know your thinking, well that only adds up to 90%… And that’s because there is technically a 3rd possible scenario, which would be this whole thing fizzled out and we get nothing at all. I would give that a 10% chance of occurring.

Right now, we can say with moderate confidence that there is increasing potential for snow (possibly accumulating) overnight Friday into Saturday morning. It is still too early to give a first call, but we will probably be able to do that Wednesday night. For now, just stay tuned and keep your fingers crossed for more snow!
