Maine faces thunderstorms and a tornado threat for Wednesday

A cold front will slice through New England Wednesday. Strong storms are expected to come along with it.

PORTLAND, Maine — We had ourselves a little taste of Autumn yesterday, but summer will battle back today. Temps and humidity will be on the rise creating lots of instability this afternoon. A cold front will provide the trigger to lift the air into strong thunderstorms.

This line will get to the mountains around noon and slowly work south, getting to the foothills and central highlands between 3 and 5 p.m. From there it will continue to sink south, getting to the coast after dinner. Here's a look at the timeline:

The largest concern with this line is damaging wind and very heavy rain capable of drainage and flooding issues. But, there are numerous ingredients pointing to the formation of supercells within the line. Supercells are rotating thunderstorms that may birth a weak tornado or two.

The Storm Prediction Center has a 5% chance for parts of Maine and New Hampshire to get a tornado. While that doesn't seem very high, we rarely see numbers like that here in northern New England. 

In the rare case a tornado forms, here are some helpful safety tips:

We'll be tracking these storms all afternoon and evening and will pass along any warnings both on TV, online, and through our various social media platforms.
