This winter has truly been the opposite of last year and it seems there is no end in sight. The blocking pattern as you can see on the NAO chart below will continue through the end of the month which means more stormy weather and the opportunity for snow events. The PNA is actually negative which makes sense because the mean trough position is actually in the Rockies. The cold air in the East is bleeding in from the north under the mean ridge position. So what we have are storms attacking the ridge that has low-level cold air under it and the result is snow as we see this morning in the Ohio Valley and later across the Northeast.
I posted the ECMWF total snow map for the storm which to me is very amazing for mid-March. It's been years since I have seen this much snow being predicted by a model this time of the year.
The Northeast is going to get walloped by heavy snow with over 6 inches in many areas. The snow is going to come quick and hard, and may be accompanied by thunder and lightning. Snow rates may exceed an inch per hour in many areas from Pennsylvania to Maine. The big cities are probably going to have just rain, perhaps mixed with some snow when it comes in.
After this storm, there is another storm that may bring snow to the South and the Carolinas later this week.

The next couple of weeks will bring several big storms.
Heavy rains will hit California this weekend and cause serious flooding.
Another snowstorm will hit Maine and add to the snowcover.
A severe weather outbreak will occur Tuesday across eastern Texas and spread into Louisiana Tuesday night.
We are not done yet as the pattern will go to the extremes with at least 3 more major storms.
