Snow Forecast Tuesday 03142017 Early Call

I think at this point an early call snow forecast map is warrented. I’m still wondering about the coast hugging option as illustrated today by the NAM model however it remains now as the only model showing a west solution. The GFS & Canadian model are in sync for the most part and would be all snow for just about everyone. There may be mixing issues for area in Coastal New Jersey from Southern Ocean County Southward and I went for lower amounts there. I kept it all snow on Long Island because in cases like this it usually stays all snow there though some south shore and east end mixing can’t be ruled out, I don’t think it makes too much of a difference. I put the western edge of 12 inches into Eastern Pennsylvania to include Allentown and Philadelphia. All of Southern New England and Southeastern NY are in the foot plus zone as well. As far as the top side of this I’m not terribly good at figuring that part out. I think the foot plus forecast indicates that this is a significant winter snow storm and if somebody winds up with more than this I would not be surprised. Snow begins during Monday evening in Southern areas and could arrive in NYC around or before midnight and should be done by late afternoon or evening on Tuesday.

The map sequence above is the Canadian model forecast today which is in line with the GFS forecast as well as last night’s European model. This would suggest a foot plus snowfall for much of the region from Washington DC to Philadelphia to New York City to Boston.

Now below are the National Weather Service snow forecast maps that were issued this morning. These only take us through 7am Tuesday so they are not total storm forecasts .
