Discussion

It starts off quite chilly this morning and remains on the cool side this afternoon despite some fading sunshine as a warm front approaches the area. That warm front can produce isolated showers around here later tonight and then temperatures should surge on Thursday following its passage with tomorrow’s highs well up in the 70’s. This front (and additional fronts) will keep it somewhat unsettled around here for the late week and weekend with a daily shot at some shower activity, and maybe a couple of thunderstorms mixed in. Looking ahead, a colder-than-normal air mass arrives in the Mid-Atlantic/Northeast US on Monday and it looks like the first half of next week will feature below-normal temperatures for this time of year.
