Discussion
Lingering showers this morning as a cold front works its way through the region and it’ll turn noticeably cooler for the remainder of the week following the unseasonably warm start on Monday and Tuesday. Canadian high pressure will take control of the weather by tomorrow and it’ll lead to excellent radiational cooling conditions later tomorrow night with clear skies and light winds. As a result, the first frost of the season is possible in some N/W suburbs by early Friday morning with overnight lows down in the 30’s.
Looking ahead to the weekend, strong low pressure will form over the western Atlantic Ocean and likely produce heavy rainfall and strong winds for the Carolinas. This system has an increasing chance of impacting the Mid-Atlantic region as well with some heavy rainfall and strong winds, but an “escape” to the east-northeast and away from the Mid-Atlantic coastline is still a scenario that is on the table. The time period of concern for the Mid-Atlantic region for rain and wind would be from Saturday night to Monday.
