This week in Colorado weather: July 18, 2022

July 18, 2022 / Ben Castellani

Another brutally hot week is expected across the Front Range with a ridge of high pressure staying the course over Colorado. With this, temperatures will remain above normal for the next six days or more, including a couple chances at reaching triple digits. Thunderstorms will be around throughout the week, but as usual they will be fairly spotty and will offer little reprieve from the ongoing heatwave and drought. A slight pattern shift early next week should revive the monsoon for the Desert Southwest, but whether that propagates into Colorado remains to be seen.

Back-to-back 100-degree days possible this weekend, more to come next week

With the monsoon getting suppressed and a hot pattern taking hold this weekend, both Saturday and Sunday could get Boulder to the elusive 100-degree mark for the first time in nearly two years. We discuss the cause of this heatwave, how hot it will get around Boulder and Denver this weekend (and next week), and when we expect cooler temperatures to arrive.

June 2022 began soggy and snowy across the Front Range with a sizable precipitation event getting us off to a good start on the first of the month. However, the rest of the June was largely warm and dry despite an early start to monsoon season in the southwestern United States. Here’s a quick and colorful graphical recap of our weather during June and how it relates to climatology.

We hope you had a great Fourth! The Southwest monsoon remains active through the middle part of the week with good chances for rain in Boulder and Denver, especially Tuesday and Wednesday. Unfortunately, the pattern shifts late in the week suppressing the flow of monsoon moisture into Colorado. This will cause drying for us, but also a spike into triple-digit temperatures for the weekend. Read on for our full outlook of the week and weekend ahead.

Summer 2022 Outlook: Monsoon season has begun early, but La Niña sticking around is worrisome for Colorado

June 29, 2022 / Ben Castellani

The arrival of the North American summer monsoon varies substantially from year to year, depending greatly on the weather patterns of Mexico, the southeast USA, and the tropical eastern Pacific Ocean. We don’t have to wonder anymore — the monsoon has already commenced in the last few days, about two weeks ahead of schedule. Hooray! We discuss the current state of the monsoon, what’s happening with that pesky La Niña, and what to expect in the coming months across Front Range Colorado.

The heat returns this week, but thankfully so do the storm chances. Highs start out near normal but reach potential record highs by midweek. Our storm chances increase Wednesday through Friday as better moisture spreads into the state, some of which will be tied to Tropical Storm Celia off the Baja coastline. Read on for all the details.

The ongoing heatwave will last through Monday with near-record high temperatures expected once again. A welcomed cold front Monday night will offer a reprieve from the heat for a couple days, but the sizzling temperatures return in full-force later in the week. We’ll largely be dry the entire week ahead. However, signs are pointing towards a surge of subtropical moisture during the upcoming weekend into the Four Corners region. This will bring the chance of late-day thunderstorms back into the Front Range.

May 2022 Graphical Weather Review: A damaging late-season snowstorm AND copius 80-degree days

June 2, 2022 / BoulderCAST Team

May 2022 began by continuing the dry trend of the months prior, but thankfully was capped off with two soaking precipitation events across the Front Range. The damaging snowstorm May 20th to 21st was one of the biggest ever in Boulder for so late in the season. On the opposite end of the spectrum, there were also 14 days of 80-degree weather during the month — a number way above normal. Here’s a quick and colorful graphical recap of our weather during May and how it relates to climatology.
