After a hot and dry Monday, the rest of the week ahead will see cooler and stormy conditions unfold across the Front Range, the the focus centered on another damaging hail outbreak on the Fourth of July holiday. Much cooler weather arrives Wednesday with at least one cold-related historical record up for grabs. The Southwest monsoon remains delayed with little hope of it arriving anytime soon. Let’s take a look at yet another active week in Colorado weather!

This last full week of June will feature hot temperatures to start followed by a cooldown late-week along with increasing chances of showers and storms. Ridging will largely be in place early on, but an approaching low pressure system and cold front will return us to more unsettled conditions by week’s end. There will also be some gusty winds Tuesday for raising marginal fire concerns. Read on for all the details.
Yesterday was absolutely wild across essentially all of eastern Colorado as dozens of supercell thunderstorms slammed the region with widespread damaging hail and flooding rains, while up to a dozen tornadoes touched down on the far eastern Plains. Fortunately, Mother Nature’s encore performance of severe weather on Thursday isn’t expect to be quite as bad, but the risk remains relatively high again for damaging hail and locally flooding downpours in the Front Range. Let’s dive in! (yes, that was a pun)
Whether you like it or not, Front Range Colorado has finally turned a corner on the cool and soggy weather lingering across the area the last few months — just in time for the first day of summer on Wednesday! While the week ahead will offer a few chances for rain, and even some severe storms at times, the overall trend heading into the end of June will be towards drier and hotter weather. Let’s take a look!
NOTICE: Due to the federal holiday, our usual Monday weekly outlook will be posted instead on Tuesday. Please check back then for the latest on Front Range weather!
June has begun exceptionally wet across the Front Range and that trend will live on this week with continued cool and rainy weather expected throughout the extended forecast. Wednesday and Thursday look to be the wettest days in the pipeline, but every single day this week will carry at least the risk of scattered storms alongside a minor risk of localized flooding. Things may finally dry out and warm up next week but don’t count on it. Read on for our complete outlook of the weather week ahead in Colorado.
May 2023 dumped more than five inches of rain on Boulder and concluded as the 11th wettest May since the late 1800s. Though there were no exceptionally warm days, the month did see an above normal mean temperature, breaking a streak of cold months stretching back to November. Other monthly headlines included multiple severe weather outbreaks and of course the thick wildfire smoke from Canada which created days of degraded air quality. Here’s a quick and colorful graphical recap of our weather during May and how it relates to climatology.
The story since late last week has been the infiltration of smoke into the Front Range from distant but numerous Canadian wildfires. That trend will unfortunately continue early in the week with light to moderate smoke sticking around through at least Tuesday or Wednesday leading to degraded air quality. Fortunately, the pattern will shift midweek whisking away the smoke and changing the headlines to rain and thunderstorms for a few days. Let’s take a look at what is sure to be another interesting week in Colorado weather!
