Synopsis
Winds ease this morning but dry conditions will continue through much of the day today. Low pressure brings accumulating snow tonight, and wintry mix during the day on Sunday. Cold high pressure then builds in early next week with very strong gusty winds. Another storm system is then possible later in the week.

Near Term - Until 6pm This Evening
6:40am No notable changes with this update, mainly just fitting temps to trends so far this morning. Also no changes on the arrival of the snow late this afternoon and evening.

Previous... High pressure departs New England today, with increasing clouds ahead of our next storm system. Highs remain seasonably cool with most spots topping out in the 20s today, and some teens across the north. A few flakes are possible before sunset today across parts of southwestern New Hampshire as the system moves our way.

Short Term - 6pm This Evening Through Sunday Night
The main focus of the forecast continues to be on a long duration storm system moving into the area tonight. Low pressure deepens as it moves through the Ohio River Valley tonight, and then tracks through the Saint Lawrence Valley on Sunday. A secondary area of low pressure develops in the Gulf of Maine during the day on Sunday, tracking into the Canadian Maritimes Sunday night.

The first round of snow mainly falls tonight across New Hampshire and western portions of Maine. This starts across western New Hampshire around sunset, spreading eastward through the evening, and reaching most of western Maine by midnight. WAA aloft helps to bring a round of snow before any warm air pushes temps above freezing aloft. This alone likely brings at least 6 inches of snow to much of New Hampshire and western Maine, allowing more areas to be added to the winter storm warning. However, this first push doesn't look like it brings much moisture far enough east into central Maine and the MidCoast, where the bulk of the activity will hold off until Sunday.

Then Sunday turns messy in most areas. The primary low moving through the Great Lakes remains quite strong, allowing temps to warm above freezing aloft all the way to the mountains. This warm air is expected to reach southern New Hampshire by daybreak on Sunday, and reach the mountains by the early afternoon. At the same time, a secondary low pressure center is expected to develop in the Gulf of Maine during the day on Sunday, allowing cold air at the surface to remain in place. Even if temperatures Probability of Precipitation above freezing for a bit during the morning right along the coast and into southeast New Hampshire, they are likely to fall back below freezing during the afternoon as the coastal low deepens.

This combination allows for a mix with and change to sleet well inland, likely all the way up into the mountains. Closer to the coast the cold air at the surface is expected to be shallower, allowing for a higher potential for freezing rain. The exact location of where the narrow freezing rain area remains tricky to pinpoint. Areas where the cold is deep enough see sleet, and rain will fall on the warm side of the coastal front. The freezing rain will be found in between, and is most likely along the coast and through southern New Hampshire. The greatest ice accretion is likely to be just to the west of the coastal front, where over a quarter inch of ice accretion remains a concern. Also a concern, where the ice does accrete, it will not have a chance to melt before the strong gusty winds arrive on Monday. Exactly where the greatest ice falls will be important for lingering impacts.

The storm moves away during the overnight hours tomorrow night, ending from southwest to northeast. Far northern parts of Somerset county stand the the best chance to see the highest totals as snow continues until almost daybreak on Monday.

Long Term - Monday Through Friday
Late Evening Any mixed precipitation changes to snow before ending Sunday night. This will leave the region under gradual clearing skies downwind of the mountains and developing upslope snow showers across the west and northwest facing higher terrain.

By Monday, ensemble solutions and latest operational model runs suggest the atmosphere will be well aligned through a deep layer with and increasing gradient over New England. Very strong and gusty winds can be expected per latest Bufkit mixing profiles. Have used the blend tool for now to increase winds over the region, but this will need to be further monitored with fresh snow and ice on the trees.

It will be frigid during this period with Arctic air over the region. Expect very low wind chill values during this period.

Thereafter, a cold but dry pattern continues for Tuesday and Wednesday. Models are in some disagreement as to whether a coastal low will significantly impact us late Thursday into Thursday night, or pass south of our waters by Friday morning.

Prev Disc... As the winter storm continues to exit the region Monday night, northwest flow will remain with a tight pressure gradient keeping breezy winds though much of the day Tuesday. A large- scale high pressure system moves in, with mostly dry conditions and slackened winds by Wednesday morning.

On Thursday, a low appears to move across the Mid-atlantic and move eastward. Though a couple ensemble members show a more northerly turn to the low, most ensemble members chart the low east of the "Benchmark" (40N, 70W) suggesting that the low is more likely to track out to sea, with lighter snowfall accumulations across New Hampshire and Maine.

More high pressure arrives behind this low, with a drier end to next week.

Marine
Short Term
High pressure crosses the waters today, bringing a break from the SCA (Small Craft Advisory) conditions. Low pressure passes west of the waters on Sunday, with a secondary low pressure center developing in the Gulf of Maine on Sunday, with Gales possible.

Long Term
Low pressure exits over eastern Maine Sunday night. A strong pressure gradient will remain overlaid the coastal waters Monday and Tuesday, leading to Gales and some gusts nearing Storm force.
