From the TV 5 Forecast Center:
High pressure will build into the area today giving us lots of sunshine. With cooler air in place, temperatures will be below average today with highs in the low to mid-40s for most locales with a few spots up north staying in the upper 30s. We’ll start the night under clear skies followed by increasing clouds after midnight as an upper level disturbance approaches from the west. With clear skies and light winds expected, temperatures will fall pretty quickly early tonight before bottoming out as the clouds start to move in. Temperatures will fall to the upper teens to mid-20s for most spots before the clouds arrive.
Clouds will be a bit more prevalent to start the day Wednesday as an upper level disturbance moves through the region. The clouds will move out during the morning and give way to more sunshine for the afternoon as the disturbance moves to our east. Temperatures will remain below average with highs in the low to mid-40s Wednesday afternoon. Clouds will be on the increase again during the day Thursday as low pressure moves through the Great Lakes. The area of low pressure will pull a warm front northward into Maine later Thursday which will give us a chance for some afternoon/evening showers. It looks like the best chance will be over northern and western parts of the state so the overall forecast looks drier for trick or treating Thursday evening. Heavier rain will move in later Thursday night and into the first half of Friday as the storm pulls a cold front through the state. The front will move east of us Friday afternoon bringing the rain to an end from west to east during the afternoon hours. Strong southerly winds ahead of the cold front will usher a milder airmass into the state with highs reaching the upper 50s to low 60s on Friday. Cooler air will return to the area during the weekend.
Rest of Today: mostly sunny with highs between 37°-47°. Northwest wind 5-10 MPH.
Tonight: clear start then becoming partly cloudy late. Cold with lows between 17°-27°. Light southwest wind.
Wednesday: partly sunny during the morning then becoming mostly sunny during the afternoon. Highs between 40°-47°. West/northwest wind 7-12 MPH.
