Monsoon season may have officially started earlier this month, but it’s off to a sluggish and lack-luster beginning across Colorado. Boulder has seen frequent storms—yet little meaningful rain—and wildfire smoke from the Western Slope and neighboring states is starting to pool to our west. A cold front arriving Tuesday night will bring cooler temps and a bump in thunderstorm chances for Wednesday, followed by a promising shift toward a more classic monsoonal setup Thursday through the weekend ahead with continued daily storms. This week, we’re tracking some heat, smoky haze, and hopefully, a few solid soakings of rain.
Wednesday brought historic heat across the Front Range, with Boulder hitting a record high of 101°F—the city’s hottest day in over a decade. A weak cold front has since cooled things off slightly, ushering in a good chance of storms the next few days as well. Sunday into Monday turn drier and hotter again as reverse monsoonal flow sets up, potentially stifling our typical summer storm pattern for a bit.
