A slight chance of showers is forecast for Memorial Day in Denver, with the odds of rain and thunder increasing in the afternoon.

While many may have hoped for a preview of summer weather over Memorial Day Weekend, forecasts showed cooler temperatures and some lingering rain on Saturday before drier and steadily warmer conditions arrive Sunday and Monday.

A slow-moving system means rain could force those planning outdoor activities in the central and southern U.S. this holiday weekend to come up with a Plan B on one or more days.
