Although there is a weak front producing a little bit of snow in northern Maine, most of New England is staying dry and on the warmer side through tomorrow.
We have a nice Wednesday with plenty of sunshine in central and southern New England, high temperatures close to 60 degrees.
A weak front in Maine continues to produce snow north of Bangor off and on today and tomorrow. Otherwise, we just see many clouds with just a few rain or snow showers possible later tomorrow, high temperature in the 30s north in the 40s south.

The weather system that brought snow to Southern California yesterday is racing across the country with more severe weather and flooding rains in the Mississippi River Valley. That storm approaches New England tomorrow night and Friday morning.
At the same time, new cold air from Canada will merge into the north side of that storm as it redevelops off of Nantucket, generating bands of wind whipped rain and snow for a Friday nor'easter.
Though there is a great deal of uncertainty on how much snow, it is likely that higher elevations get at least several inches, rain may change to heavy snow even at the coastline. If it gets cold enough fast enough, blizzard conditions are possible along the coast.
Temperatures will be holding the 30s or even falling a little bit during the day Friday.
Wind at the shore will be from the northeast sustained 25 to 35 mph, with gusts past 50 mph. This will generate wave heights over 20 feet with a possible storm surge of 2 to 4 feet during the afternoon. Friday high tide is before moon, as the storm is ramping up.
The worst of the storm surge may occur as the tide is going out Friday afternoon.
There is a full moon so the probability of coastal erosion and flooding is quite high.
The storm system should move just far enough off shore on Saturday that were left with clouds and just a few raindrops and snowflakes, but wind at the coast will remain strong from the north 25 to 30 mph. Seas will continue running high, so coastal erosion continues on Saturday, possibly into Sunday, at north facing beaches.
It looks like quieter weather for the weekend and early next week, before a potential second nor'easter in less than a week arrives with potentially more wind, rain, and snow by Tuesday or Wednesday.
