We are likely to enter a period this weekend with cooler temperatures and a better chance for periods of clouds and thunderstorms across the central Rockies, including the Front Range region. The change might start out slowly Friday or Saturday and become more noticeable Sunday and Monday.
It should still be quite warm in most areas, but some moisture from the tropical Pacific will increase the chance of late day cloudy periods and some localized showers or thunderstorms. The pattern is an early taste of the Southwest monsoon.
A cool front from the north may arrive by late Sunday bringing in cooler weather. Cloudy periods late Sunday into early next week may be more numerous and there may be a late day period with more organized coverage of showers and thunderstorms on Sunday or Monday.

We have a hot summer weekend coming up with low elevation temperatures topping 90 and probably reaching mid 90s in a number of areas. A cool front Sunday night should trim about 10 degrees off the high temperature for Monday, but that’s still a warm day.
No organized areas of rainfall are expected and even isolated showers will be hard to come by. The main weather may be increasingly windy conditions both before and after the cool front Sunday afternoon and Monday. Those winds may enhance the risk of wildfires especially in the western and southern parts of the state where the vegetation is drier.

A weak and mainly dry cold front will be passing through the Front Range region late today. Its main impact will likely be to kick up the wind a little today and reduce the temperature a little on Saturday. Sunday will probably be a little warmer than Saturday.
This is the time of year when a small chance of afternoon thunderstorms often exists. I expect it to stay dry today and tomorrow. The chance for thunder returns on Sunday, but it is a low chance for any one location. Above average temperatures are likely as we go into the early part of the work week.
