October 2024 Graphical Weather Review: Wrapping up the driest May to October period ever recorded in Boulder!

November 14, 2024 / BoulderCAST Team

October was yet another exceptionally warm and dry month in the Front Range, with most areas landing more than six degrees above average while receiving very little if any precipitation. The period of May to October only produced 4.64″ of precipitation in Boulder, the driest such stretch in recorded history. It’s no surprise that drought has further expanded across the region. In contrast to our boring weather, space-related activity was booming in October with multiple nights of auroras lighting up Colorado’s skies and a multi-week comet display. Here’s a quick and colorful graphical recap of our weather during October and how it relates to climatology.

We also discuss the shift back to sunny and dry conditions for the upcoming week.

Winter Weather Update: Another round of snow moves in Tuesday night through Wednesday, worst in the southern Metro area (Updated)

November 5, 2024 / Andy

A new storm system will drop across far western Colorado Tuesday night, but it’s heading for the deserts of southern Arizona. In the process of bypassing the Front Range, it will bring light snow to the Denver Metro area starting Tuesday night as temperatures tumble below freezing. Intermittent snow showers and flurries will linger through the day Wednesday leading to minor accumulations in Boulder and Denver, but higher totals are favored further south. There is also the potential for a more impactful storm to hit our area on Saturday, but that continues to look more unlikely by the day. Read on for the latest on the chilly and unsettled days ahead.

Updated (Tue 11/5/24 7:00 PM): The higher-end outcomes we touched on in the original post have become more likely give the latest model guidance. Though some snowflakes are already flying, we have amended our snowfall forecast map with a slight increase of 1-2″ across the board for the Metro area. Remember this is a long duration (mostly light) snowfall event, lasting from Tuesday evening at least into Wednesday afternoon. Light snow may continue well into Wednesday night, but this is still uncertain. Forecast snow totals will be reached over time, not immediately.
