The good news is that there are now and will continue to be some breaks in the overcast letting the sun through at times this weekend. The bad news is that there will be more rain each day, and possibly in the form of a heavy thunderstorm.
The large scale pattern continues to support weak storm systems from the southwest and ample moisture from both the Gulf of Mexico and the Pacific. Intervals of partly sunny skies should occur each day. But the little bit of heating during the sunny periods should be enough to trigger more showers and thunderstorms. Some thunderstorms today (Saturday) may be strong, with brief heavy rain and hail, especially out on the eastern plains. Both Sunday and Monday are likely to see some shower and thundershower activity along with some partial clearing intervals. The best chance for rainy periods is in the afternoon and evening, with some areas of fog or drizzle in the late night or early morning.
West slope areas are getting these rounds of showers and thundershowers too, so be prepared for lightning and rain if you are in the high country. Although the odds slightly favor a rain-free Bolder Boulder 10K race on Monday, you should have a plan for rain (or at least drizzle) if you are going to be there.
