Good morning!Clouds will limit sunshine again today and most of Maine will stay cool. Lewiston to Brunswick and west into NH the heat will return with high humidity that will trigger showers and thunderstorms. Some storms could produce locally heavy rain and flash flooding along with strong,gusty winds and feq lightning!!Storms will diminish Overnight leaving us in the warm and sticky air again with patchy clouds and fog. A slow moving cold front will develop another round of showers and thunderstorms tomorrow that could produce heavy rain as the air remains warm and humid.If the front stalls near the coast on Friday it could be a wet and cooler day. Stay tuned.Saturday a mix of sun and clouds with an isolated shower or thunderstorm.Sunday looks dry and partly sunny.Both days will feature seasonably warm temperatures and lower humidity.Have a great day!
