Major Nor'easter Brewing; 1-2 Feet of Snow Possible

Maine looks to be the hardest-hit area

A blizzard watch has been posted for southeastern Maine, and may be expanded south and west. The storm now looks like it is going to slow down and intensify close to the New England coast Sunday night and Monday.

In the meantime, we still have residual snow from Friday night hanging on in much of the state of Maine, and it's actually trying to back south and westward on Saturday afternoon. Fog and drizzle around Boston and points north may make for icy side roads and sidewalks the rest of Saturday and especially Saturday night.

The best weather is in southwestern New England,where we have breaks of sun in Connecticut and close to 40 degrees. For most of us, Saturday's temperature is in the 20s to low 30s. Partial clearing on Saturday night will allow for spotty black ice expanding inland and west, temperatures in the 20s south, and teens north.

Patchy light snow and freezing drizzle early Sunday will become widespread and heavy during the afternoon. By evening, most of our roadways are becoming snowy and slushy; the exception is right along the coast in Connecticut, Rhode Island, and southeastern Massachusetts, where it may be warm enough for rain.

Sunday night we get heavy snow, with rain changing to snow along the coast. Temperatures will be dropping into the 20s south and teens north. Wind from the northeast will increase to 20 to 40 miles per hour by dawn Monday.

Low pressure stalls and intensifies rapidly near Cape Cod on Monday. This will cause heavy snow, blowing and drifting, with possible blizzard conditions for coastal eastern New England, including Boston and Cape Cod. West of the Connecticut River, snow should be later and we may have some sunny breaks.

Temperatures hold in the 20s on Monday, with wind increasing from the northeast at 30 to 50 miles per hour, gusting past 75 miles per hour at the coast.

Seas will be building to 15 to 25 feet, and high tide at midday will feature moderate coastal flooding and major erosion.

Snow will gradually taper off near the shore late in the day Monday, but continuing in the state of Maine. Snowfall totals of 1 to 2 feet are likely, heaviest in Maine, where amounts may exceed 2 feet. Wind continues strong Monday night blowing and drifting snow.

Valentine's Day on Tuesday should feature a mixture of sun and clouds with diminishing wind, high temperature in the 20s to near 30 degrees.

Another front from northern Canada arrives on Wednesday, with low pressure once again developing over the Gulf of Maine.

We may see another powerful nor'easter with heavy wind and snow again Wednesday night and Thursday.

This pattern is starting to remind us a lot of February 2015.
