Upcoming Weather Summary
The mild weather will continue through Labor Day, but noticeable changes are on the way by Tuesday. A weak low-pressure system will bring moisture and instability to the region:

As noted in the Area Forecast Discussion, “The severe thunderstorm threat looks very low with possibly more of a heavy rain and urban and small stream flooding potential.”
Looking Ahead
Post-storm, expect a brief return to pleasant conditions for Thursday, followed by a warming trend heading into the weekend. Further disturbances may bring chances for showers and storms Friday night through Sunday.
