The atmosphere is gearing up for a dramatic mid‑week pivot, and the Front Range is about to feel every bit of it. We start the week under a warm, bone‑dry ridge that will send temperatures soaring and fire danger spiking—especially by Wednesday, when downslope winds and exceptional dryness are set to collide. But just as quickly, the pattern will flip. A pair of incoming troughs will drag us into a cooler, unsettled stretch of weather heading into the weekend, with several chances for much‑needed moisture and even the prospect of a few snowflakes mixing in at times. It’s a true tale of two patterns this week! Read on for all the details.
