A stark change in our weather is set to take hold for Friday as we move from seemingly never-ending summer heat to a much cooler and rainy setup that will bring with it a significant flood risk to the Front Range. The remnants of Tropical Storm Harold and a strong Canadian cold front will align almost perfectly over the area late Friday into Saturday with more than 1″ of rainfall possible and even more locally. In this update we discuss the latest timing of everything, the temperature nose dive, rainfall amounts, and which areas are at greatest risk to see flooding.

The week commences on the hot and dry side as a very strong and anomalous ridge over the central United States keeps much of Colorado locked into a scorching heatwave. Remnants from a tropical cyclone over the western Gulf of Mexico may influence our region later in the week as it interacts with a southward moving cold front. This should favor cooler temperatures and increasing chances for thunderstorms by the latter part of the week into the weekend. Read on for all the details of yet another semi-active weather week for us.
A ridge of high pressure will remain in control of Colorado through the extended and even intensifies this weekend keeping us mostly dry and hot. The best chance of rain in the pipeline comes on Friday, but only limited rainfall is expected from storms due to a lack of moisture. Additionally, the remnants of major Hurricane Hilary in the Eastern Pacific will arrive to the USA this weekend but stay well to the west of Colorado unfortunately (boo!). Things dry out further this weekend into early next week as temperatures once again make a run towards triple digits in the Denver Metro area.
The week begins on the cooler side, but don’t be fooled! Hot weather, including potential record-breaking heat, is lurking right around the corner as temperatures return to the 90s by Tuesday and stay there the rest of the week. Rainfall will also be hard to come by during this toasty stretch. Let’s take a look at the hot and dry weather week ahead…

The weather this week in the Front Range will have two contrasting primary themes. A heat dome cooking beneath a large ridge of high pressure off to our southwest will push temperatures towards record highs Monday and Tuesday. However, the rest of the week will exhibit a cooling trend with increasing chances for late-day thunderstorms as several backdoor cold fronts team up with increasing monsoonal moisture. Yes, the famed monsoon season is about to commence! In typical fashion though, there will also be a risk of some severe weather mixed in. Let’s take a look at what should be yet another interesting weather week…
