Was Monday really the hottest September day ever in Boulder?

September 6, 2019 / BoulderCAST Team

Labor Day 2019 was Denver’s first 100-degree day ever to occur in September. It was also the latest 100-degree day observed, remarkably by more than two full weeks. The previous record high for September 2nd was 95 degrees. On Monday, this temperature was eclipsed before the lunch hour, with the prior record eventually being obliterated by 5 degrees later in the afternoon. The city of Boulder officially hit the century mark on Monday, too. The extreme heat had impressive historical significance here as well, with one small asterisk. Unlike Denver, Boulder actually only tied all of the existing records, as 100 degrees had already been observed on the very same day back in 1983. We investigate the validity of the triple digit observation this week and the one more than three decades ago.

This week will feature a figurative roller-coaster ride in temperatures across Colorado. This is thanks to the first fall-like storm system of the year scooting across the northern United States. It will be predominately dry for us, but rain chances do return late in the week.

A change to the weather pattern has taken place early this week with a noticeably drier airmass establishing itself across Colorado and the monsoon moisture plume redirected well to our east. Ultimately this will translate into a drier and warmer period in the near-term.

We begin the first full-week of August on the hot side but trend slightly cooler as the week wears on thanks to monsoon moisture returning back into the area from the southwest. Read on for more details.

It’s hard to believe that August is now upon us! Where is the summer going? June and the first half of July were cooler than normal with summer barely making an appearance. The heat has really ramped up over the last three weeks though, including a ten-day stretch of 90-degree weather in Boulder. Should we expect more of the same in August? Read on as we examine Boulder’s climatology and consider the current state of the atmosphere to give our outlook for the next month.
