Scattered storms next two, but not the entire time... 

A warm day on Friday with morning scattered showers and perhaps a thunderstorm, then additional scattered thunderstorms will be possible in the afternoon and evening. In between any shower or thunderstorm activity, intervals of clouds and sun are expected.

A cold front will follow Saturday additional scattered thunderstorms possible, but the activity should be limited to just the morning hours, with partial clearing in the afternoon. Additional late day or evening thunderstorms will be possible in spots., then drying out for the 2nd half of the weekend with cooler temperatures and breezy, but pleasant behind the front. It remains dry early next week, although still cooler with a breezy northwesterly wind on Monday. The next system will approach midweek with an increase in clouds and late day showers, and those showers are likely to evolve into steady periods of rain and will continue into Thursday most likely along with cool temperatures.
