Snow has now moved into southern Maine and will continue the rest of the evening becoming heavier and steadier through 9PM before winding down in the Portland area by midnight. Down East the snow will linger longer and there is a winter storm warning for heavier amounts of snow there.
I'll be updating the snow forecast as it changes on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.
How much snow?
The system is moving very fast and this is a good thing as it will keep amounts down to light to moderate levels. The map below was my thinking earlier today and I still feel comfortable with these numbers. If the system keeps chugging along Portland will end up on the lower end of the scale, but this is why I have the range to allow for slight discrepancies in speed and intensity of the system.
When does it start and end?
The snow will overspread the rest of the area this evening and wind down around midnight or just after. In other words, it’s a very short window of falling snow. If you are thinking school is going to be cancelled Wednesday, think again.
Cold midweek, but milder finish
The cold continues into Wednesday when highs will still stay in the upper 20s to lower 30s, Portland won’t break freezing tomorrow. The good news, temperatures will warm further on Thursday along the coast, but staying colder inland and up north. This time of the year the sun is very weak and the only way we really melt snow quickly is with a mild rain. Friday is even milder with highs into upper 30s to low 40s for some real melting, at least on driveways, walkways and south facing areas. There could be some rain showers on Friday as well with the milder air.
There is going to be some unsettled weather later this weekend. I am not sure just yet where the boundary between the cold and warm air will set up, but I am leaning towards more of a rain event along the coast south of Portland and a mix north and west, but it’s very early in the game.
