I normally post a little overview of the weekly weather on Sundays. But tomorrow I'm going to be a bit busy with outdoor activities So I'm posting this now.
This week
The weaker clipper with the rain and snow that came through yesterday into this morning is off the coast. In its wake it left cool temperatures.
We have a stronger clipper approaching the Great Lakes, Associated with that, there is a Leading warm front and a trailing cold front dropping south out of Canada. Where is the warm front We are going to see mild air stream into Pennsylvania and the northern Middle Atlantic. The cold front is going to drop south and east during the day, North of the front Most of New York state And northern into central New England Is conning to stay on the cool side of things. with temperatures becoming above average across Pennsylvania into the northern Middle Atlantic. This is going to set up a boundary over the region. There will also be quite a bit of atmospheric moisture over Pennsylvania into the northern Middle Atlantic as well .

With the front we will see some snow and a winterly mix on the northern side. For most of southern New England, Southern tier of New York State into the northern tier of Pennsylvania, northwest New Jersey and through Long Island a general slushy coating is possible on grassy surfaces. Across northern New York State and northern into central New England. Especially in the higher elevations. General snowfall amounts for northwest and northern Massachusetts into much of northern New England and across northern New York State looks to be a general coating to two or three inches. But snow could be rather heavy in the Adirondacks, Greens and Whites. Leading to higher accumulations, the Adirondacks could see 3-6+ inches. While parts of the Greens into the Whites possibly pick up 5 to as much as 12+ inches of snow. Generally most of Maine not in the mountains we'll see 2-6 inches of snow. With far northern Maine seeing. 1-2 inches.
With widespread rain and some thunderstorms along and south of the front. some of these thunderstorms could be strong too severe. Those with the greatest chance of seeing severe thunderstorms will be across Pennsylvania into western Maryland. The storm prediction center (SPC) has a Slight Risk there. With a Marginal Risk for severe weather Into New Jersey, eastern Maryland and Delaware. Generally the best time for any severe weather will be 2:00 PM to 8:00 PM. After that the severe threat will lessen But we are still likely to see some non severe thunderstorms moving through the Middle Atlantic during the overnight Into Monday morning.
The risk will be damaging wind gust and a chance for large hail. During the afternoon we will have to be on the lookout for discrete supercells that could develop ahead of the cold front. During the late afternoon into the evening the super cell threat will diminish And we will see an increased chance for a few clusters or lines of thunderstorms that could develop. Besides the risk of damaging winds and large hail; there will also be a chance for frequent lightning, torrential downpours and even a few tornadoes.
High pressure will be building into the region for Monday,as most of the region should be dry but there will be lingering snow out across Maine. Monday into Wednesday is looking a bit cool with slightly below average temperatures likely. Then on Thursday temperatures moderate a bit and become more seasonal. The seasonal temperatures will extend into Friday But then another cold front will come through and drop our temperatures back down to slightly below average for the weekend. With the the front we will likely see some snow/mix showers over northern parts of the region Especially in the higher elevation, with rain showers for the southern half of the region.
One thing I want to point out, I'm saying the low average quite a bit. But remember, what is considered average temperatures are higher than the day before. So below average doesn't mean bone chilling cold. At this point in March our general average temperatures are 50's into 60's °F. So our temperatures will be a little lower than that.

We still have that monster ridge over the western into central US, that continues to strengthen. This is going to allow that northwest flow to continue across our region. This is the predominant pattern that we've seen for most of this winter. As that continues it's going to continue to keep the Northeast cool. Here's a look at the climate prediction centers (CPC) 10-14 day temperature outlook.
The ridge is going to work its way east over the next several days. As that occurs We are going to see the ridge trough pattern across the US flatten out a bit. For the next several days Temperature should generally remain overall slightly below average. But as we get into the first part of April the overall general setup will make it feel more like spring.
