This first major heatwave of 2023 will unfold this week across the Front Range as a broad ridge of high pressure produces bountiful sunshine and an influx of warm air from the southwest to Colorado. Multiple days of record high temperatures are expected as most of us soar into the 80s. However, late week a big cooldown is taking shape with rain/snow likely returning on Friday. Read on for all the details of the crazy weather week ahead.
This winter has definitely felt longer and colder than any in recent memory. We review some temperature statistics to show that not only has it been an exceptionally cold winter overall, but the lack of any true warm days thrown into the mix made things feel even more extreme.
March 2023 concluded as the coldest March in more than 50 years in Boulder and was our fifth consecutive month with below normal temperatures — this winter has been atypically long and brutal. Despite heavy snow fueled by atmospheric river events in the Mountains, very little precipitation reached east of the Continental Divide during March with fire danger and blowing dust increasing substantially by month’s end. Here’s a quick and colorful graphical recap of our weather during March and how it relates to climatology.
After widespread snow and unseasonably cold weather on Monday, things quiet down for the midweek period with a nice warm-up headed to the Front Range. A secondary storm system will reach the area Thursday into Friday with Mountain snowfall ramping up again along with another chance of snow in the Denver area to close out the month of March. Read on for all the details.
Despite persistent and exceptionally cold weather, March has under-delivered on snow thus far with less than 2″ falling in Boulder since late February. More snow and cold is on the way Sunday night into Monday, but once again it looks to be another meager showing of snow. As of writing, uncertainty remains regarding exactly what will transpire with this event as a band of heavy snow may develop early Monday somewhere across the northern Front Range. Let’s take a look at the timing of everything, the most likely snowfall amounts, and the potential travel impacts as winter weather returns for the last Monday of March.
This week’s weather will feature a resurgence of winter across the Front Range, but in typical fashion it will be immediately preceded by a few days of spring-like conditions including potentially our first 70-degree day of 2023. The bottom is set to fall out Wednesday night with rain changing to wet snow across the region. Though there is still some uncertainty due to the lead time, accumulating snowfall looks very likely for almost everyone in the Metro area. Read on for our complete outlook of the weather week ahead.
February 2023 was a chilly exclamation point on what was ultimately Boulder’s 2nd coldest winter in 30 years and the coldest since 2010. This very icy status was solidified by one of the most pronounced late February cold snaps on record. Here’s a quick and colorful graphical recap of our weather during February and how it relates to climatology.
