This weekend will surely feel a lot different than recent ones as the first autumn storm system of the year arrives into Colorado — conveniently aligning with the official first day of autumn on Sunday. While a fair amount of uncertainty remains in potential precipitation totals for the Front Range, everyone should see an extended period of light to moderate rainfall from late Saturday afternoon into Sunday morning. Fortunately it is still too warm for frozen precipitation across the lower elevations, but snow will fall in the Mountains accumulating up to several inches. Here’s our latest thoughts on what has turned out to be a tricky storm to forecast!

The second week of September will bring a prolonged period of unseasonable warmth to the Front Range along with minimal rainfall. The early to mid-week period will actually have slight chances for rain, but late-week will have much drier air and gusty winds leading to elevated fire danger. Temperatures will remain close to 90 degrees every single day in the extended, with some influx of wildfire smoke at times from the Pacific Northwest. Read on for all the details.
August brought welcomed change to the Front Range with the elusive American Southwest Monsoon finally making a late appearance. While much of the area ended with below normal rainfall in August, it was notably wetter than months prior leading to a slight improvement in the regional drought. It was also hot in August, with overall temperatures and the number of 90-degree days landing above normal. Here’s a quick and colorful graphical recap of our weather during August and how it relates to climatology.
September is finally upon us — what a great time of the year this is in Colorado! Mother Nature will deliver rather varied weather this week in the Front Range. Hot temperatures and high pressure will give way to a Pacific trough by midweek. Clouds will be on the increase alongside the risk of severe thunderstorms for Wednesday, with even a touch of snow in our highest elevations. Things will clear out nicely for the upcoming weekend leading to gorgeous and seasonal late-summer conditions. Read on for all the details.
NOTICE: Due to the Labor Day holiday, our usual weekly outlook discussion will be published a day later on Tuesday this week. Please check back tomorrow for the latest on Front Range weather. Early week weather highlights are as follows:
⦁❶⦁ High pressure is centered directly over Colorado Monday but it will slowly weaken as we head into midweek
⦁❷⦁ Expect sunny skies this morning, but increasing clouds during the afternoon and evening — an isolated thunderstorm is possible with little to no rain and gusty winds
⦁❸⦁ More or less the same exact weather for tomorrow but perhaps a degree or two warmer
⦁❹⦁ The week ahead will be largely dry, except for late Wednesday when a weak storm system will clip northern Colorado
Labor Day Weekend won’t be quite as hot as it was on Wednesday, which was Boulder’s 40th 90° day of the year, but we are expecting warm and dry conditions to persist, perfect for any outdoor activities you may have lined up. The weather pattern will shift slightly early next week with the potential for isolated storms returning to the area. Whether you’re planning a trip into the Mountains or are staying comfortably down low in the city this holiday weekend, read on for the latest forecast details!
