The forecast calls for a foggy start Friday morning for commuters in the Denver and Fort Collins areas, according to the National Weather Service in Boulder.

“Use caution if traveling,” the weather service tweeted.

But things are expected to clear up later in the day in Denver, with a high near 53 degrees, sunny skies and light winds, the weather service predicts. Similar conditions are projected for Saturday and Sunday, with temps in the high 50s and low 60s.

But the weather could take a shift Sunday night, with a storm possibly moving in that could produce rain and snow to kick off the week. Monday’s forecast calls for a high near 42 degrees with breezy conditions and possible snow starting by early morning.
