Thunderstorm activity will actually increase tonight as a piece of energy moves through the area. Some of these storms may become severe with damaging winds and heavy rainfall.

A thunderstorm complex over the midwest will move eastward tomorrow morning, bringing a chance of morning rain or thunderstorms to the area.

Highs will be in the upper 80s.
