Baltimore/DC winter storm watch, snow amounts from clipper
Hey everybody. First the update of the day, a winter storm watch has been hoised for all of Maryland west of the Chesapeake Bay including Baltimore, Washington, Hagerstown, and Fredrick in anticipation of more than 5 inches of snow being a possibility Saturday into Saturday night. There maybe more mixing south of a line from Washington DC to Annapolis and Dover. North of that line I expect all snow from this situation and mainly overrunning snow. Assuming that occurs and the coastal storm has minimal impact on us, I suspect will see a 6-8 inch snowfall across north central Maryland and possibly less snow in southern Maryland of 2-4" with ice on top of that and maybe even a bit of rain mixed in in lower southern Maryland. That's the early estimate here. Below is the NWS statement on this winter storm watch and will continue to monitor this closely.

We also received 1.8" of snow here in Essex, MD in southeastern Baltimore County yesterday and 1.1" yesterday at BWI with 0.08" QPF and 1.2" of seasonal snowfall. There was 0.8" of snow at Reagan National in Washington bringing the seasonal total up to 0.9" and finally there was 3.0 inches of snow at Annapolis, Arnold, and Bowie, MD, which were our highest totals from Wednesday in Maryland. Now we watch and wait to see what Saturday and Saturday night brings us and what impact if any the coastal storm has on our weather Sunday. Right now the coastal impacts on Sunday look minimal from the stand point of snow, otherwise this would be a blockbuster snowstorm for the megalopolis. But that trend will continue to fine tune as well.

You can have freezing rain at 15 degrees if conditions are right. All you need is for the cold air to be shallow and right at the surface.

But snow also?
Brent, you said that it can freezing rain at 15 degrees. That I can imagine. It's 15 at 0 feet and 55 at 1000 feet above the ground. but the forecast had called for "*snow* and freezing rain" at 27 degrees. Can it do that? If it does, then the upper layer must be right around 32 degrees, and unless the layer is really shallow, like mid-skyscraper height, it seems to me that the rain would freeze before it hits the ground and you would get snow and sleet instead.

Kinda sucks doesn't it? The last three systems here have been sleet and freezing rain with the temps around the low 20s upper teens. It all has to do what the temp is in the upper layers of the atmosphere like someone else stated b4 me

I'm not sure about that. I just know there was freezing rain at about 15 degrees in Washington State this past weekend. I was pretty shocked as well.

Dawn in Harford Co here. Been looking for you, waiting for your post. Only 5 inches? Wishing for more.

Hi Dawn. At least 5 inches of snow is possible and that I think is conservative. Some areas of northern Maryland will likely see a band of 6-12" of snow accumulation from midday Saturday through midday Sunday. If this coastal storm does develop and intensify closer to the coast, it could means even higher snow totals. But right now I'm going with a solutions that indicates 6-10 inches along the MD/PA border with isolated totals nearing a foot. I'm looking at 6-8 inches at BWI and down into Annapolis and Washington DC. Totals of 3-5 inches is possible in southern Maryland assuming snow mixes with sleet and freezing rain. Snow could linger in southern Maryland through Sunday morning and into early Sunday afternoon. So 3-5 inches in southern Maryland maybe somewhat conservative. Will see how this shakes out. At the very least this is expected to be the first significant snowstorm of the season and given how much snow we've seen this season, definitely deserved.
Take care and be prepared for this storm. It's certainly a storm I wouldn't take lightly.
Jim
