What's next:

Tomorrow provides our greatest chance for showers and thunderstorms across the area. While it won’t be raining all day, showers and storms will be possible at any time of day. Highs will be in the mid 80s and it will be humid. Some communities could pick up a heavy downpour. There is a small chance of a gustier storm. 

Showers and storms will continue tomorrow night and then on Friday will favor our southern counties, particularly south I-80 with a continued shower threat. The majority of our area will just be partly to mostly cloudy and not as warm with high temperatures not far from 80°. 

A stretch of dry and warming weather will begin on Saturday. Highs will be in the mid 80s on Saturday, then upper 80s Sunday. 90+ is likely Monday and Tuesday with plenty of sunshine continuing.
