“Enjoy today while it lasts!”

That’s what the National Weather Service in Boulder said in a recent tweet. That’s because Denver is forecast to see a high near 69 degrees on Tuesday with sunny skies before winter returns over the next couple days.

“Colder and wet weather is coming on Wednesday,” the weather service tweeted.

Rain could start falling by Wednesday afternoon, the weather service predicts, before it possibly turns into snow in the evening. The snowfall is expected to last until Thursday afternoon as temps are forecast to stay in the 40s and 50s on those two days.

The heaviest snowfall is expected to stay in areas west and south of Denver, the weather service says.
