Finally Friday's Forecast

Cooler air continues to slowly sag into the area on Friday leaving 50s out west and 60s and 70s east. Spotty showers are expected in NE Wyoming, but most of the area will be dry until a potent wave of instability works in from the southwest on Friday night. Widespread showers are expected for Friday night with some thunderstorms in south central South Dakota along that front.

Extended Forecast

Saturday's temps will be noticeably cooler yet before another even stronger wave works in Saturday night. This one will produce more rain and more will hit the ground as the atmosphere becomes increasingly saturated. Some snow may mix in Friday night, but will be more common on Saturday and Sunday nights.

Spotty occasional showers continue Sunday and Monday before the system slides too far east. So by Tuesday and Wednesday of next week, we can anticipate drier and slightly warmer conditions.
