Tuesday December 17 2019

Fog is developing this morning and could become pretty thick over the next few hours. This is thanks to warmer moist air is ‘trying’ to move in over the cold and wet ground. That supersaturates the air at the surface and ‘poof’ we get a ground cloud we call fog. Some spots may hav ice in pockets in the mountains and southern PA, mainly on trees and colder surfaces. Roads are being reported as wet. Most of our region is above freezing.

This afternoon a car ride will operated who stays in the 30s and who reaches the 60s. Farther north, an ice and snow storm will continue to rage in northern PA, New York, and New England. Following that storm a true load of arctic air spill our way for Wednesday.

High Temperatures Today

There will be less than 100 miles separating the 30s from the 60s on Maryland’s Lower Eastern Shore.

The NAM 3 Km Model is coldest keeping Baltimore in the 30s. The European ECWMF and GFS Models bring the 40s to Baltimore, but 50s close to Annapolis.

Wednesday Winter Air Returns

This is most likely across Pennsylvania and northern Maryland. But some flakes could get close to Metro Baltimore


Temperature Outlook

I’ve highlighted the model spread of temps in Baltimore today. Check out the drop over the next two days!  Nearly freezing in Baltimore on Thursday means 20s inland.  A gradual moderation to the 50s is possible before Christmas.  Note that the model accuracy one week away is not the best. There will be some adjustments to the holiday forecast.
