The weather week ahead in Colorado will initially be focused on a series of weak shortwaves tracking from west to east across the state. A more potent trough will develop later in the week but uncertainty lies in its overall track and moisture availability this far out. Together these systems will lead to low-end chances of showers and storms each day this week, although most of us will see more dry time than not. As for temperatures, they will mostly hover a few degrees above normal in the lower 80s each day — a fitting end to the summer season which wraps up on Friday!

On this first full week of September, an overall dry pattern will exist across the Front Range with plenty of sunshine to go around. The best chance of storms will be during this Labor Day with a strong cold front moving east, though we suspect almost all of the action will be well north of the Denver Metro area. Tuesday will see temperatures drop pleasantly into the 70s behind a cold front, but it will be a short reprieve as above normal temperatures regain control in the days to follow.
A ridge of high pressure will remain in control of Colorado through the extended and even intensifies this weekend keeping us mostly dry and hot. The best chance of rain in the pipeline comes on Friday, but only limited rainfall is expected from storms due to a lack of moisture. Additionally, the remnants of major Hurricane Hilary in the Eastern Pacific will arrive to the USA this weekend but stay well to the west of Colorado unfortunately (boo!). Things dry out further this weekend into early next week as temperatures once again make a run towards triple digits in the Denver Metro area.
Temperatures and precipitation ended up about as close to normal as possible for July in Boulder. The month began active with numerous severe weather outbreaks, some of which produced landspout tornadoes in parts of Denver. The last few weeks turned up the heat with a total of fifteen 90-degree days during the month. Here’s a quick and colorful graphical recap of our weather during July and how it relates to climatology.
June 2023 dropped more than 5″ of rain on Boulder for the second straight month, concluding as the 4th wettest June since the late 1800s. Temperatures ended up nearly 4°F below normal as well, including a monthly minimum temperature of 42°F which occurred in the middle of the afternoon on June 12th as several inches of small hailstones lay melting on the ground. Other Front Range headlines in June included minimal Canadian wildfire smoke, the Highlands Ranch EF1 tornado, and the pummeling of giant hail at Red Rocks.
