Snow Becomes Heavy This Afternoon As It Changes To Rain Near The Coast

Hello everyone!

Today’s forecast will be a complex one as low pressure intensifies basically right overhead. Snow is already beginning across the area this morning, and will continue to expand in coverage and intensity as we head through the middle part of the day.

Along the coast, snow will continue through the mid afternoon hours when warm air will slowly creep inland, resulting in a change to rain. This change will happen earliest along the midcoast, and latest in the Casco Bay area. Expect 3-6″ of snow for most of this area before heavy rain develops for the later part of the afternoon. The exception may be along the peninsulas of the Midcoast where warm air will invade most easily. 1-3″ can be expected there.

For inland areas, snow will last deeper into the afternoon, with the changeover coming later than at the coast. Not only will it come later, but it will be a different flavor of changeover, from snow to ice and sleet instead of snow to rain. 6-12″ of snow can be expected before ice and sleet develop this evening. Total icing of up to .2″ is expected, and while that’s not enough for power outage concerns, it will be enough to cause very slippery conditions on the roads.

In the mountains, deep cold air will remain locked in place today. An all snow event is expected north of route 2, with many locations seeing 8 to potentially 16″ of snow. The very end of the event may bring a few ice pellets or freezing raindrops, but the vast majority of the system will be snowy. Enjoy the powder at the ski areas!

Rain, snow, and mixed precip moves out this evening with NW winds bringing a shot of bitter cold air for tomorrow, along with robust upslope snow showers.
