The big picture meteorologically has a front come through Sunday morning, stalling to our south, followed by a storm riding on the front early Monday. The front itself will bring some light precipitation tomorrow with up to an inch of snow possible, but many areas seeing just a few flurries. Across Cape Cod and the Islands the snow could be mixed with rain or even just plain rain for this part of the day, but it will become all snow once the bulk of the storm arrives Sunday night.
On Sunday night a renewed area of snow will move across the region. The snow will be heaviest late at night and the first part of Monday well south of Boston. Additionally, the snow will be most intense along the south coast.
All models are keeping the heaviest snow south of the area. Many times this winter, the models have insisted the snow would stay south only to have it move further north in actuality. The data I have reviewed this afternoon continues to push the snow further south, based on this information, I feel even less snow will fall than I did this morning.
This map is for snow that will fall Sunday morning through Monday morning.
I will update the forecast and snow totals here and on Twitter @growingwisdom.
The snow will be light and not very wet, so whatever you do receive can be easily moved. There will be moderate to heavy amounts of snow from Hartford to Washington, DC. If you have travel plans Sunday and Monday to or from those areas you can expect delays and cancellations to be likely.
As the storm pulls away later Monday the snow will end as cold arctic air stays firmly in place. Highs Monday will stay in the lower 20s, at least 15 degrees below the 30 year average of early March temperatures. More cold air greets New Englanders on Tuesday when highs again remain well below average.
It will turn less cold later next week. Temperatures will recover above freezing by Thursday and Friday. It’s not going to be warm, but there will be some melting of the snow.
Another storm threatens early next weekend.
