Watch out for a few slick spots out there today with low clouds and a fine light wintry mix of snow, sleet and freezing drizzle pushing through this morning. Lows have fallen into the 20's and gradually warm back into the Lwr-mid 30's this afternoon with some improvement. It is a cloudy, cool overcast day, with very spotty light precipitation along with a light onshore flow.
Light rain and drizzle will begin to redevelop or fill in over New Hampshire this evening and mix with sleet in the colder areas in the North and west. Strong SW winds aloft along with an upper level trough swinging east from the Great Lakes will direct a low pressure system west of New England Sunday. Rain will quickly fill in and become heavy for a time from the midday into the afternoon. Downpours will be possible along with an embedded thunderstorm with a widespread 1-2" of rain falling by the time it tapers off Sunday night.
A strong low level jet 5,000 feet above our heads will have winds screaming aloft up to 90-100 mph. Some of the downpours will be able to mixing that energy down to the ground. We should expect a period of strong winds to develop Sunday as this rain moves through. Winds will be from the ESE wind direction with the highest gusts to be found at the coast and the mountain tops. Winds at the coast could gust over 50 mph for a time Sunday. The strongest winds will actually shift from coastal MA to Coastal ME where we could see the potential for damaging winds with gust to 50-60+ mph Sunday afternoon.
The Strong southerly flow from the south will direct very mild, possibly record warmth for central and southern New England. Despite the rain and wind, highs will climb into the 40's and 50's. Once the front pushes off the coast Sunday night, NW winds will direct much colder air back into the region Monday where highs will struggle to reach 32 degrees with significant cold air advection draining in from Canada.
Another upper level trough will be swinging east Tuesday and Wednesday. A low pressure center will track from the Great lakes to North of New England, but a secondary low will develop and strengthen in the Gulf of Maine. Light snow will be arriving Tuesday night and Continue at least into Wednesday morning. There is a ton of energy of with this and the potential for some explosive development. It is not a big storm, but it will have the potential to drop a few inches of snow for the midweek, with colder 20's following in to end the week.
What about Next weekend in the 17th-18th time frame? Latest model runs are taking the low south of us with drier solutions and not as much of a stormy look. We will continue to watch that as well. For now I think we have enough on our plate!
