Discussion
A slow-moving strong cold front will continue to slowly trek across the nation over the next couple of days and it’ll remain to our west through most of the day on Thursday. As a result, it’ll stay warm and quite breezy around here on Halloween Day with occasional showers likely. As the front arrives later tomorrow night, there is likely to be a period of heavy rainfall going into the overnight hours along with possible strong thunderstorms. There can be some residual rain early Friday, but it’ll soon push off the east coast and temperatures will be some 10-15 degrees lower compared to the unusually warm conditions expected on Halloween Day. Even cooler air will arrive in the Mid-Atlantic region by the latter part of the weekend and it looks like an overall cooler-than-normal weather pattern will continue through much of the first part of November. (By the way, this is the weekend in which we turn the clocks back an hour).
