Discussion
The passage of a weak frontal system will usher in a slightly cooler air mass to the Mid-Atlantic region for the mid-week and then a much stronger front will cross the area on Friday. As a result, showers are likely on Thursday night and early Friday and there can be a thunderstorm or two mixed in as well. Much cooler air will follow this late week cold frontal passage for the upcoming weekend and a reinforcing chilly air mass will arrive during the early part of next week with the chance of snow and/or rain showers.
