First, the snow happening now through Thursday morning should only be a dusting to an inch in central and N MD while S MD could see a couple inches. As the evening is progressing I am noticing that the dew points, moisture in the air, are increasing and the snow is filling in nicely. That pattern should help us for Friday.
Friday does not look to be the major storm I once thought it had the potential to be. But true to form with the storms this winter; the models in the long-range show nice storms, only to take them away in the short-term. I don't yet have a 100% forecast for Friday, but here is how I see it shaping up.
TIMING: Late afternoon into the evening. Some flakes could be seen earlier, but honestly, the greatest snow impact could be around the evening commute.
PRECIP TYPE: All snow. The snow should be fluffy and so power outages and tree damage is unlikely.
ACCUMULATION: This is still not 100%, but realistically we could see around 2 - 4 inches in most areas. Slightly higher in S MD. Some localized areas could see a burst of snow.
CONCERNS: It does appear, similar to this evening, that the dry air I am concerned about can be overcome. If that is the case accumulation rates will be higher. Another factor is the slight chance for a re-formation of the Low near the coast. If that happens than areas south of Baltimore could see an increase in accumulation.
All in all this is not a big storm, but given the cold air it will be nice to have snow to go along with it.
I will have another update later Thursday. Follow me on Twitter (@wxmanmd) for frequent weather updates and tidbits.
