A strong cold front on Friday is expected to bring cooler weather late Friday through Sunday. There is also a good chance for clouds and areas of rain and thunderstorms late Friday into early Saturday.
There may end up being more than one push of cool air from north to south on Friday, so it’s possible that the real cool down may not occur until late Friday. With northeasterly winds accompanying the arrival of the cooler air, some moisture may be pushed upslope into the Front Range increasing the chance for showers and thundershowers. There may even be a multi-hour period of overcast with some steady drizzle or rain late Friday into early Saturday.
Denver, Boulder, and Fort Collins have all been running drier than average for June-July-August (Colorado Springs has not been as dry). So if this push of cool air late Friday manages to trigger some widespread rain, that moisture would be welcome.
