Cooler air will settle into the Northern Colorado Front Range Foothills on Friday with widely scattered afternoon showers and thunderstorms possible. The weak trough of low pressure responsible for the cooler temperatures and unsettled weather will rotate out into the Central Plains Friday evening. In its wake a ridge of high pressure and moderating temperatures will be in store on Saturday and Sunday. Both days will be predominant dry with abundant sunshine. If you are heading up in the mountains, especially in central Colorado, a stray shower can’t be ruled out either day, but Nederland should be dry. Models continue to hint at a weak disturbance cutting across Colorado and the Central Rockies Sunday night and Monday. This system does not have much energy or moisture to work with, but with instability from daytime heating it doesn’t always take much to set off showers and thunderstorms in early July. However, any rain that does fall will be brief. Tuesday still looks to be dry and warmer, perfect for Fourth of July activities. Much warmer temperatures are on tap for the middle of next week.
A fire ban is now in effect for the foothills of Boulder County. Winds appear to be generally light through the weekend, but some higher gusts will be possible in the vicinity of showers and thunderstorms.
