Denver is preparing for a week of extreme weather fluctuations, starting with a mix of wind, rain, and snow on Sunday. Meteorologist Joe Ruch is closely monitoring these developments, highlighting an impending transition to a historic heat wave later in the week. The initial cold conditions, characterized by precipitation and gusty winds, will give way to record-breaking temperatures, potentially surpassing historical highs for this time of year. Residents are advised to take precautions against both the initial cold snap and the subsequent extreme heat, including staying hydrated, seeking shade, and avoiding strenuous activities during peak heat hours.
