Yesterday afternoon Portland changed from cold rain to heavy snow despite a screaming east wind off the 41 F ocean.

That's the kind of winter it's been. Or more specifically, the kind of February it's been. I'm not sad to see us turn the calendar to March personally...although it is statistically our snowiest month (bet you didn't know that!).
Rest of today: The main portion of yesterday's storm is now to our north but the upper level low associated with it is stalled directly over Maine. As a result look for mostly cloudy skies with scattered snow showers and some rain showers possible closer to the coast. To the north there is more organized activity (since the low is still nearby), so periods of light snow will solidify by late this afternoon with 3-6" of accumulation likely towards Caribou and down to Millinocket. Temperatures will be seasonably mild, 35-40 F in most spots.
Tonight: Light snow continues over northern Maine but most of us are just cloudy with a few scattered showers. Temperatures won't drop that much, into the upper 20s to low 30s, but it will be enough that any precipitation that falls will be in the form of snow. I don't expect any accumulation outside of northern Maine.
You know I'm all for long and detailed forecasts, but with the upper level low sitting on top of us for the next few days I don't see much distinction in the day to day forecast through the weekend.
When you get an atmospheric log jam like this the key is attempting to time out the little "waves" of energy that spin out from the main upper level low. In this case I think the strongest impulse moves through on Saturday with some light snow shifting from Downeast Maine all the way down the coast through the day. So on Saturday I'd say we have a chance for some light accumulation.
Otherwise the forecast is the same from Friday through Monday: Mostly cloudy, scattered snow showers inland and scattered rain showers along the immediate coastline, high temperatures in the upper 30s to low 40s, overnight lows in the upper 20s.
That about covers it.
By Tuesday the upper level low should become "vertically stacked" which means it will weaken itself by running out of dynamics, so sunshine should begin to win out at that point.
Ok I'm out of here!
