1;40 PM MDT, Friday, June 14, 2019
Today will be the last very warm day for a few days, although it’s not likely to get very cool. Expect the weekend to be a little below the average (average high temperatures for mid June in Boulder-Denver is low 80s).
The atmosphere is unstable today, but not very moist in the low levels. So incidents of heavy rain and hail in thunderstorms should be localized. Most areas probably won’t see significant rain, but are more likely to see gusty winds from thunderstorms outflows. It appears that Saturday will be a bit more moist, so there may be more coverage of rain in afternoon/evening thunderstorms, and then maybe back to a slightly drier trend on Sunday.

Today should be a typical early June day with afternoon temperatures climbing above 80 in the lower elevations and the development of a scattering of afternoon/evening thunderstorms. Saturday will start out on the warm side of the cold front, but during the afternoon (maybe late morning in Cheyenne) we are likely to see a windshift to the northeast and a trend toward cooler temperatures. A generally cloudy period is likely late Saturday into early Sunday with some thunderstorms late Saturday and maybe some fog or drizzle Saturday night or Sunday morning. The clouds will probably break up during the day Sunday, but temperatures will likely remain below 70 for the highs Denver, Boulder, Colorado Springs and Fort Collins.
Although the shift to cooler weather will be statewide, the magnitude of the cool-down and the chance for rain will be lower in West Slope areas.
