Yesterday evening, a cold front left strong showers and thunderstorms across the Great Lakes, including the Chicago area. That same cold front is slowly but surely moving East and will control the weather conditions here in the Northeast for much of the holiday weekend. Today, deep southerly winds will drag abundant moisture across Maine. The moisture, together with the diurnal heating and the cold front already in place will be key ingredients for scattered showers and thunderstorms to develop.
Tonight the unsettled weather will continue in the early evening hours then turning mostly cloudy. Conditions will feel sticky overnight and into Sunday morning as dewpoint temperatures remain in the 60s and very close to the actual temperature. Sunday we could see peeks of sunshine, allowing temperatures to warm up slightly higher than today. Upper 70s to lower 80s expected on Sunday with Southerly winds again dragging moisture in to Maine. Showers and thunderstorms will develop, especially throughout the afternoon.
Your Labor Day Holiday is also looking a bit wishy washy, with mostly cloudy skies and the chance of scattered showers and isolated afternoon thunderstorms. Temperatures will cool down as the front begins to move away.
Overall, we will see scattered showers and isolated thunderstorms throughout this holiday weekend. Good news is that it will not be a complete wash-out of a weekend! Make it a great one!
