Our latest winter storm will arrive later today, bringing with it a diverse blend of precipitation types. Before the system arrives, thickening clouds and cold temps can be expected as high pressure digs in to our north.
Snow will break out from SW to NE this afternoon. SW NH can expect flakes a little after 3 PM, with Maine’s snow waiting until later in the afternoon/evening. The evening commute will be snowy, especially south and west of Portland, but should be entirely doable if you’re careful.
Snow becomes heavier tonight, with rates of 1-2″ per hour expected across the area. Snow will change over to sleet in SW NH beginning around 10-11 PM, with the mix progressing NE early tomorrow morning. The far NW mountains have the best chance at remaining mostly snow, while the vast majority of the region sees at least a bit of mixed precipitation.
Sleet will change to freezing rain for parts of southern NH and SW ME very early tomorrow morning, with up to 1/4″ ice possible. This will be more than enough to cause slick travel conditions, but shouldn’t be enough to cause major power disruptions. A cold front will put an end to precip tomorrow morning.
Accumulations will range from over a foot up at Sugarloaf to 6″ in SE NH. Most of the region will see between 6 and 10″ before the change to sleet.
