Forecast discussion: A cold front is now passing through Boston, which brought a little light rain Tuesday evening. Skies will begin to clear before midnight, as high pressure will briefly give us some morning sunshine. Also, temperatures are going to get colder, as a strong air mass from Canada comes down and stays over New England.
As we head into Wednesday morning, a coastal low will develop near New Jersey, and bring the threat of more showers by the afternoon. The heaviest precipitation will remain offshore, but there will be some sprinkles as the World Series begins. Temperatures will be quite cold, so please dress warmly if you are heading to Fenway. Clearing skies are expected a few hours before dawn.
High pressure covering the Southeast U.S. will bring mostly sunny skies into Friday, with some increasing clouds expected on Saturday. Temperatures will be near freezing Friday night, so you may want to bring in any plants that may still be growing. By Saturday night, a low pressure system coming down from Canada and into the Great Lakes. This system may provide us with some showers Saturday night into Sunday afternoon. By early next week, the colder air aloft will slowly retreat towards the north. So, our temperatures will return to normal conditions for the end of October. It will keep a low pressure system away from us, but we could see showers by early Wednesday morning.
