The Southwest Monsoon will remain active across Colorado this week with the best chances for rainfall coming Wednesday through Friday in the Front Range. Storm chances will be greatest across the Mountains with better forcing, upslope, and unstable air leading to a slight risk of flash flooding there. Temperatures during the week in the Denver Metro area will remain near or above normal, but fortunately nothing too hot. Let’s take a look.
NOTICE: Due to unexpected travel, our usual weekly outlook discussion will be published a day later on Tuesday this week. Please check back tomorrow for the latest on Front Range weather. Early week weather highlights are as follows:
⦁❶⦁ A narrow plume of monsoon moisture will fuel numerous thunderstorms across the Front Range on Monday during the afternoon and evening
⦁❷⦁ Favorable shear will also be present increasing the risk for severe storms — heavy rainfall and golf ball-sized hail are the primary concerns, but damaging winds and a couple tornadoes also possible
⦁❸⦁ High temperatures reach the upper 80s in the afternoon before the storms cool us off
⦁❹⦁ Tuesday will be the only completely dry day this week as temperatures rebound back well into the 90s
⦁❺⦁ Thunderstorms will be in the forecast Wednesday and beyond with 30-50% chances each day
Rain chances in the Front Range will be front-loaded this week with a moist monsoonal flow in place. Temperatures will consequently hover near average in the 80s with plentiful clouds and storms developing each day, some of which could cause localized flash flooding. Rain chances will remain for the latter part of the week, but coverage lessens significantly as drier air is forecast to move in. We’ll also likely see the return to the 90s by week’s end. Read on for all the details.
Our scorching hot, two-week-long heatwave will finally come to an end later this week, but not before we endure a few more days. A cold front is slated to arrive into the Denver area late Wednesday finally knocking us out of the 90s. This front will also come with an enhanced chance of rainfall, though monsoon moisture is still largely lacking. Despite daily chances for rain this week, our existing fires will continue to smolder and the risk of new fire ignitions remains uncomfortably high.
Between the extreme heat, thick smoke and new wildfire ignitions, this week has been quite the disaster in the Front Range! Our fuels have been primed for weeks now and our team has been vocal regarding this inevitable outcome, but things unravelled much quicker than even we expected this week with something like ten wildland fires in the Front Range just since Monday, in total burning more than 9,000 acres of forest! The weekend unfortunately won’t offer much reprieve from the heat, fire or drought, but we are tracking a potential shift next week towards wetter and cooler conditions. We provide an update on the local fires, the ongoing heatwave, the widespread smoke, and when actual raindrops may return to the forecast.
