The Front Range kicks off October with a stretch of warm, dry weather—perfect for leaf peeping and outdoor plans. After a brief chance of storms on Monday, highs climb into the 80s by midweek under mostly sunny skies. But this unseasonable warmth and sunshine won’t last forever: a late-week system could bring cooler temps and a renewed shot at rain or even Mountain snow. Read on for all the details.
This week’s weather kicks off with a dramatic autumn shift—widespread rain, clouds, and a serious temperature drop that will bring snow to the High Country. A strong cold front and upper-level system will make Tuesday feel more like late October, with highs stuck in the lower 50s. But don’t worry, sunshine and warmth are on the horizon again. By midweek, we’ll rebound into the 60s and maybe even flirt with 80 by Friday. Curious about how much soaking rain we’ll get—or where that snow might land? Read on for all the details.
After a sunny and warm start to the week, the Front Range will trade blue skies for gray as a sluggish low-pressure system settles into northeast Colorado for several days. Rain chances build Tuesday and linger through Thursday, with well below normal temps and a few rounds of storms in the mix. But don’t expect a soaking: rainfall totals may vary widely, with the heaviest action likely landing northeast of Boulder and Denver towards Nebraska. The storm exits sometime Thursday leaving behind drier and warmer weather for the weekend.
