Snow Today into Tonight. EURO versus GFS for This Weekend

February 8, 2012; 10:52 AM ET


The HRRR model snow accumulation image has been posted below. For most folks, this is a coating to an inch or two storm. It will snow hard at times but most roads should be just wet. It possible that roads get snow covered after dark, especially across eastern Pennsylvania into New Jersey.

The big battle comes this weekend. An arctic front will plow across the eastern part of the country Friday into Saturday. Snow squalls should accompany the frontal passage, but the big issue is whether a storm develops along the coast or not. I put the GFS and Euro models below that shows the difference between the two models. The GFS just has a frontal passage while the Euro has storm developing on the coast and more widespread snow. The NAO is not that excited for a coastal storm, so I think the compromise is an wide area of light snow that goes from the Great Lakes, Ohio Valley through the mid-Atlantic with amounts in the coating to 2-inch range.
