The Southwest Monsoon will remain active across Colorado this week with the best chances for rainfall coming Wednesday through Friday in the Front Range. Storm chances will be greatest across the Mountains with better forcing, upslope, and unstable air leading to a slight risk of flash flooding there.

Premium BoulderCAST Daily – Mon 08/19/24 | Large hail & heavy rain will accompany monsoon thunderstorms Monday, drier but hot on Tuesday

NOTICE: Due to unexpected travel, 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:

This Week in Colorado Weather: August 5, 2024

Our scorching hot, two-week-long heatwave will finally come to an end later this week, but not before we endure a few more days. A cold front is slated to arrive into the Denver area late Wednesday finally knocking us out of the 90s. This front will also come with an enhanced chance of rainfall, though monsoon moisture is still largely lacking. Despite daily chances for rain this week, our existing fires will continue to smolder and the risk of new fire ignitions remains uncomfortably high.
