This Week in Colorado Weather: November 18, 2024

This week’s weather will be a mixbag across Colorado, with a little bit of Mountain snow, bouts of gusty winds, and one or two sizable temperature swings for the lower elevations. With the exception of a cold and windy Tuesday, the week ahead will be pretty nice for us overall. Looking ahead, a juicy atmospheric river may reach Colorado during the upcoming weekend with substantial Mountain snow in the works. Read on for all the details.

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

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.

Winter Storm Recap: Impressive week-long snow & water totals will ease the Front Range drought

The well-advertised late-week winter storm delivered widespread wet snow to the entire Denver Metro area and nearby Foothills Thursday into Saturday, with some rain mixing in at times across the warmer northern tier. We review the soupy snowfall totals from this final bout of winter weather that put a bow on the lengthy cold and snowy week in the Front Range.

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

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.

Winter Storm Recap: First snow of the season is in the books for most western suburbs, including Boulder, but it wasn’t much…

Many western suburbs of Denver experienced their first snow of the season last night, with Boulder officially recording 0.2 inches. The colder, higher elevations to the west saw a more significant dump, up to 15 inches in some areas. We briefly recap the underwhelming first snow of the season and announce the winners of our 2024 First Snowfall Contest.

Winter Weather Update: Accumulating snow likely Sunday night and again midweek, but we’re also tracking potential blizzard conditions late week for eastern Colorado

The first two storm systems of the season capable of producing snow across the lower elevations mostly missed the mark, with only a small portion of the Denver Metro area reporting snow so far this season. Neither Boulder or Denver have officially received any snowfall since April. That will definitely change this week, perhaps as early as Sunday night as a light round of rain changing to snow is expected. Furthermore, a complicated, unsettled weather pattern will unfold the rest of the week in Colorado keeping our temperatures well below normal with almost daily chances for more rain and snow. We’re fairly confident everyone will see additional light accumulating snow Tuesday night into Wednesday, with a potential for a more impactful storm late in the week into the weekend, including possible blizzard conditions. We truly have a lot to cover in this week’s outlook, so let’s dive in!
