Front Range Colorado is bracing for a scorching stretch ahead as a powerful heat dome settles in, sending daily highs into the 90s and even near 100°F come Friday. Fire danger is also set to rise with bone-dry downslope winds ramping up in the days ahead.

Record-breaking temperatures will be the story this week in the Front Range, though there’s plenty more to discuss. While a brief cooldown is on the way Tuesday, it comes with a catch—a chance for severe storms, depending on how quickly low clouds clear up. Then, just as we get a break, another scorching heatwave arrives on Thursday through the upcoming weekend, with several days of triple-digit temperatures that will shatter records. Let’s dive into the details.
Get ready for a classic early summer setup—plenty of warmth, a hint of storm potential, a bit of wildfire smoke, and maybe even the year’s first 90-degree day(s) for the Front Range. While the week starts off dry and sunny, a few scattered storms will make an appearance midweek, adding a little variety to the forecast. By the weekend, the heat cranks up as a strong ridge sends hot air northward into Colorado.
May 2025 brought cool, rainy days to the Front Range, nurturing lush, green landscapes ahead of what is expected to be a hot and dry summer. The month also featured striking weather events, including a few picturesque tornadoes nearby and multiple rounds of snow blanketing the high Foothills. Here’s a quick and colorful graphical recap of our weather during May and how it relates to climatology.
As we step into the first full week of June, get ready for more cool and wet weather in the Front Range! A promising rain event kicks off the week Monday afternoon through midday Tuesday, with a cold front bringing much cooler temperatures and widespread showers and storms. Rain chances will linger through much of the week ahead, though uncertainty remains on exactly how things will unfold from midweek onwards. Expect highs to drop from the 80s Monday into the 50s Tuesday, and continue to run below average the rest of the week. If you were hoping for a dry stretch for early June, you might need to adjust your plans—keep those umbrellas handy!
As we roll briskly into Memorial Day weekend, the forecast is shaping up to be a mix of weather conditions across the Front Range. Thursday and Friday will be pleasant, but by the weekend, a slow-moving weak storm system will shake things up, bringing cooler temperatures and a higher chance of showers and thunderstorms, including some severe risk. If you’ve got outdoor plans, definitely stay weather-aware, but don’t let a little rain spoil the holiday fun! Continue reading
