Tonight will be mostly cloudy and cool with lows in the mid-50s overnight. A few isolated showers are possible Sunday but there will be plenty of dry time during the day. It will be 10 degrees colder than Saturday with a high falling to 66 degrees, feeling even colder due to the cloud cover.
We aren't stuck in the 60s for long, a warm front moves in on Monday afternoon, bringing a chance of showers and potential rumble of thunder but a breezy southeast wind will take over and bump temperatures close to 70 degrees. The real effect of the front hits on Tuesday with more heat and humidity for September as highs will be in the 80s with storm chances by the afternoon hours. More of the same is expected for Wednesday and into Thursday with the passing of a cold front to knock us back where we belong temperature-wise: in the 70s with a drier weekend ahead.
