A low pressure system moved into Eastern Colorado Monday night, November 6 through early Wednesday morning November 8, bringing two rounds of snow to portions of Eastern Colorado. The first wave impacted northern areas, mainly Boulder, Larimer, and Weld Counties Monday night/early Tuesday morning, while the second wave impacted southern areas Tuesday night, favoring Pueblo and Fremont Counties. Denver metro received very little snow with either of these waves. Below are some of the snowfall totals for Colorado with this system (sources: NWS local storm reports, and Cocorahs).

This occurred about 10 days earlier than the average first date of measurable snowfall, and is also the first October snow in Denver since 2013. Here are some of the snowfall totals for eastern Colorado and the Front Range foothills via NWS local storm reports.

A pleasant fall weekend is in store for Colorado with mild temperatures and lots of sunshine but Sunday evening winter will be making its first appearance for many locations along the I-25 corridor from Fort Collins to Colorado Springs. A potent winter-like storm will move through overnight Sunday into Monday resulting in accumulating snow and sub freezing temperatures ending the growing season. Precipitation will fall as all snow in the foothills with a brief period of rain expected for the I-25 corridor before changing over to all snow. Snow will fall moderate to heavy at times impacting the Monday morning commute. Snow and blowing snow will continue through the day Monday diminishing Monday evening from north to south. Snow totals will likely end up on the low to mid single digits from Fort Collins through Denver with up to a foot of snow or more in some foothill locations. Lesser amounts of snow south of the Palmer Divide into Colorado Springs but they will get some snow as well. As the storm pulls away Monday evening temperatures will plummet into Tuesday morning. Now is the time to drain the sprinklers and pick what you can out of the garden before damage can be done. Enjoy the first snow of the season!
It’s going to be a GREAT Mother’s Day Weekend for baseball at Coors Field! The Rockies look to take the series from the division rival LA Dodgers Saturday and Sunday, maintaining their hold atop the NL West. If the boys are able to extend their winning streak this weekend, the Rockies could also keep pace with the Houston Astros for MLB’s best record. The suspense is building, but will the weather cooperate?
Saturday – First Pitch 8:10pm MDT
Temperatures will climb into the low to mid 80s Saturday afternoon, with game-time temperatures a comfortable 75 degrees. Expect mainly clear skies and pleasant conditions throughout the game, with light SE winds at 5-10mph. You may want a light jacket, as temperatures will fall into the low 60s by the 7th inning.
Sunday – First Pitch 3:10pm MDT
Pitcher Antionio Senzatela goes for his 6th win on Sunday, hoping to keep pace as one of the league’s top right-handers this season. Afternoon temperatures will be a little cooler, with highs topping out in the upper 70s to near 80 degrees. Expect partly cloudy to mostly sunny skies throughout the game, keeping sunscreen and sunglasses on the list for fans. There is a slight chance for a stray afternoon shower or thunderstorm, but it looks like we’ll stay generally dry. Still, pack that rain jacket along just in case.
The first meaningful weather system in nearly a month brought some much-needed moisture to eastern Colorado late Thursday through Friday morning, March 24th. Much of the precipitation fell as rain from metro Denver northward, while changing over to heavy wet snow above 6,000′ south of Denver. The heaviest snowfall amounts occurred over the Palmer Divide, which combined with very strong winds from the north to result in blowing and drifting snow. Here are some of the preliminary snowfall reports from local NWS spotters.
March 23-24 Snowfall:
- 11.0″ – The Pinery
- 11.0″ – Black Forest
- 10.5″ – Ponderosa
- 10.5″ – Falcon
- 9.0″ – Walsenburg
- 8.0″ – Woodland Park
- 7.1″ – Larkspur
- 7.0″ – Watkins
- 6.0″ – Castle Rock
- 6.0″ – Conifer
- 4.8″ – Bennett
A downslope windstorm impacted the Front Range and eastern plains of Colorado on Monday, March 6th, following a Pacific cold front that moved through the area. This type of event is known as a “Bora wind event”, which differs from a Chinook wind event in that prevailing wind directions are from the northwest and temperatures are colder (given that it follows a cold front) than the typical warm temperatures associated with Chinook winds. Also, Bora winds tend to spread farther out onto the plains whereas the strongest Chinook winds are usually concentrated near the foothills. During bora wind events, the higher elevations along the Continental Divide often receive periods of heavy snow, while areas east of the Divide along the I-25 corridor remain mostly dry due to the downsloping nature of the winds. Given the dry conditions that have developed over the past several months east of the Continental Divide, fire danger remains especially elevated during these high wind events. Here are some of the peak gusts reported across central and eastern Colorado on March 6th from NWS spotters.
- 85 mph – Swissvale (Fremont County)
- 83 mph – La Veta Pass
- 83 mph – Berthoud, 5 miles SW
- 80 mph – Wolf Creek Pass
- 76 mph – Breckenridge near 13,000 ft.
- 73 mph – Nederland
- 71 mph – Colorado City
- 70 mph – Applewood
- 70 mph – Akron
- 69 mph – Trinidad
- 68 mph – La Veta
- 65 mph – Masonville
- 63 mph – Cherry Creek Reservoir
- 61 mph – Ft. Morgan
- 57 mph – Boulder
- 57 mph – Black Forest
- 55 mph – DIA
- 54 mph – Broomfield
February of 2017 produced very little in the way of snowfall for eastern Colorado along the I-25 corridor with well above normal temperatures. Both Pueblo and Colorado Springs produced temperatures that resulted in the 3rd warmest February on record while Denver came in at 6th warmest on record. All 3 cities produced a new monthly record high on the 10th with Denver reporting 80 degrees which smashed the all time record for earliest 80 degree temperature. The warm February will probably mean some payback is coming in the spring during the latter half of March and April. Will have to see how that plays out but we need the moisture around here to keep the fire danger from elevating.

After several years of drought, California is experiencing a huge winter for moisture so far, especially in the month of January. Heavy rain and snow this month is helping to replenish water tables and reservoirs, and is making snow-thirsty skiers very happy with the first above-average snow season since 2010-2011. A series of moist Pacific storm systems have hit the Golden State this January, the latest of which brought more heavy snowfall to the Sierra Nevada Mountains this past weekend. Mammoth Mountain Ski Area has now received 246″ of snow in January, shattering it’s all-time monthly record for snow (in any month!), the previous record of which was 209″.
Here are some of the most recent snowfall totals as reported on Monday morning, January 23rd by NWS Reno spotters.
- Heavenly Ski Area – 30″ in 24 hours (88″ in 5 days)
- June Mountain – 60″ in 48 hours
- Mammoth Mountain – 41″ in 48 hours (300″ base at the summit!)
- Incline Village – 20″ in 24 hours (67″ in 5 days)
- Sugar Bowl Ski Area – 24″ in 24 hours
- Northstar Ski Area – 29″ in 24 hours (96″ in 7 days)
- Squaw Valley Ski Area – 29″ in 24 hours (97″ in 7 days)
- Mt. Rose Ski Area – 20″ in 24 hours
- Homewood Ski Area – 21″ in 24 hours
