If you thought yesterday was beautiful, get outside Friday around Denver, because it is going to be even better. But a big change is in store starting Saturday afternoon into Sunday.

Friday’s forecast calls for mostly sunny skies, with a high near 88, according to the National Weather Service in Boulder. A south southwest wind will blow between 5 to 8 mph, becoming east southeast in the afternoon.

This could be the last high above 80 for the month too.

“Today will be the last day of above normal temperatures and dry conditions,” the NWS said. “Breezy southwest winds and low humidities will lead to near critical fire weather conditions mainly for Lincoln county and the Palmer Divide through early evening.”

Tonight it’ll be mostly clear, with a low around 55. East southeast wind 5 to 8 mph becoming west in the evening.

Here’s the 4-day forecast from the National Weather Service.
