DENVER, Colo. – The Front Range wakes to crisp air and brilliant stars this morning, setting up another stretch of sunlit calm before cooler air moves in midweek. It’s a picture-perfect start to November — clear, dry, and a touch too warm for jackets by midday.

According to the National Weather Service in Boulder, temperatures climb into the upper 70s today and stay mild through Monday before easing back into the 60s Tuesday. Winds remain light and variable, offering smooth travel along I-70 and I-25 through at least midweek. Clear skies will dominate daytime hours, with only thin high clouds drifting east of the Rockies on Monday afternoon.

By Tuesday, a weak system skims northern Colorado, nudging cooler air down the plains. Highs will drop closer to seasonal norms in the low 70s, and nights dip into the upper 30s to low 40s. No precipitation is expected, though meteorologists note longer-range models hint at a stronger front developing by next weekend that could bring a brief rain or snow mix west of the Continental Divide.

Residents can take advantage of the mild pattern to finish outdoor cleanup or early holiday lighting before winds shift again later in the week. Gardeners across Jefferson and Adams Counties should plan to protect tender plants as overnight lows trend cooler by Thursday.

La Niña’s lingering influence favors these early-season temperature swings — sunny spells followed by sharp cooldowns — a setup typical of early November in Colorado. For now, fall holds firm, but hints of the season’s first snow could arrive before Thanksgiving.
