Denver is waking up to clear skies and temperatures around 59 degrees Monday morning, but the heat will build quickly. The city is headed for a sunny afternoon near 90 degrees, with light winds and only a small chance of a shower or thunderstorm.

Monday Starts The Warm-Up

Monday will stay mostly sunny through the afternoon, with southeast winds between 2 and 6 mph. Skies turn partly cloudy Monday night as temperatures dip to about 63 degrees.

Tuesday Brings More Heat And Wind

Tuesday looks hotter, with a high near 93 degrees and north winds of 5 to 10 mph that could gust as high as 18 mph. A slight chance of showers and thunderstorms arrives Tuesday night, with the broader plains facing the potential for gusty winds or hail if a stronger storm develops, according to the National Weather Service.

Wednesday Is The Week’s Stormiest Turn

Wednesday brings a modest cooldown to around 88 degrees, but afternoon showers and thunderstorms become more likely, with a 40% chance of precipitation. The Denver-Boulder forecast office says the day could bring scattered storms and a few strong to severe thunderstorms across the plains, so outdoor plans may need a little flexibility.

Sunny Skies Return Before Weekend Heat

Thursday should be sunny and near 90 degrees, followed by another sunny day Friday with a high around 94. Rain chances remain low on both days, but the heat returns in force Saturday, when temperatures could reach 95 degrees before afternoon storms become possible.

Sunday stays warm near 92 degrees, with showers and thunderstorms likely after noon and a 55% chance of precipitation. In other words, the weekend forecast currently looks like sunshine first and storm clouds later, a familiar late-summer arrangement along the Front Range.

No Alerts Are In Effect Monday Morning

No watches, warnings, or advisories are in effect for the forecast area Monday morning. Still, residents should plan for water breaks during the hottest afternoon hours, check on people who may be vulnerable to heat, and never leave children or pets in a parked vehicle.

Denver officials advise using air-conditioned buildings or designated cooling locations during extreme heat and recommend limiting strenuous outdoor activity during the hottest part of the day, according to the City of Denver. With several days in the low to mid-90s ahead, that advice is worth keeping handy even before any formal heat alert is issued.
