Storm to bring snow for interior, mix to the coast

The latest

Everyone starts off as snow. There are still questions on how much sleet is going to work in and how far inland it will go. There is also the outside chance for some light freezing rain for the shoreline areas. Wednesday will feature a tough start everywhere. Plan accordingly.

Impacts throughout the Northeast

If you are traveling by train, plane, boat or automobile around the northeast Tuesday, expect delays and cancellations. Most everywhere sees wintry precipitation, and wind. If you must travel, allow for plenty of extra time. If flying, check with your airline. 

The onset of snow
​

Snow begins to overspread southwestern areas Tuesday afternoon. It will expand northeast into Tuesday night and cover the state by early Wednesday morning. For those traveling overnight, expect greasy roads and reduced visibility. 

Snowfall idea tweaked

I've adjusted the snowfall map to include the northeastern areas in the 8-14" category, and tightened up the 6-10" region closer to the coastline. My idea for the Portland area is 4-8". Away from the shorelines, roughly a half a foot on the low end appears reasonable. How much higher it goes depends on how much sleet works into the area, which begins over southern areas in the wee hours of Wednesday. Northern areas from Jackman over to Millinocket north appear to be snow, which could bring a foot or more. South of that line is where it gets tricky, hence why I have lower end minimum points. 

Snow tapers from southwest to northeast Wednesday afternoon into the evening. Snow showers will continue over the mountains and Allagash region into Thursday. 

Outlook through Saturday

Looking ahead, Friday is a bit of a question mark. This morning one model idea having heavy rain statewide, but that idea shifted this afternoon, so I will stick with my original idea of mix to rain potential posted here Sunday evening.

I will update on that as well as well as the impending storm Tuesday morning. Check Facebook if no update here.
