The holiday weekend will start with a mild Friday but with the return of some gusty chinook winds in and near the foothills. After a cold front Friday night, near average winter temperatures will return. Then on Monday or Monday night an arctic cold front may begin a multi-day stretch of very cold weather with a chance for light snow or freezing drizzle.
Windy and mild Friday
Temperatures on Friday are likely to be in the 50s throughout much of the Front Range urban corridor, maybe even 60 in a few spots. Above average temperatures are likely throughout Colorado and southern Wyoming. Chinook winds may develop with some localized gusts exceeding 50 mph in and close to the foothills.
Trend toward colder
By Saturday a colder air mass should be in place across the region, but temperatures should be near average over the weekend with intervals of sunshine. There may be some areas of light snow in the mountains, particularly in southern Colorado.
The trend toward colder will kick into high gear early next week. It’s too early to tell if the very cold weather will arrive Monday or Monday night, but when it gets here we are likely to be in for a stretch of very cold and generally cloudy days with some snow or freezing drizzle around.
