Periods of unsettled weather Fri & the weekend. Hard to pin down the timing of the best chances of t-storms, but there will be a couple rounds interspersed between many dry hours through the weekend. Above average temps with dew points in the 70s will make for a muggy weekend. pic.twitter.com/rqnUcy5O4v
