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

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
- Tahoe City – 17″ in 24 hours
- Homewood – 17.8″ in 24 hours
- Boca Reservoir – 12″ in 24 hours
- NWS Reno – 7.6″ in 24 hours
The town of Alamosa, located in the typically dry San Luis Valley in between the San Juan and Sangre de Christo Mountain Ranges, has now set a January record for snowfall with 17.4″ through Wednesday January 18. And of course there are still almost two weeks left to go this month! This month’s snowfall breaks the old record of 15.8 inches set in 1939. Alamosa is known for being a cold, dry location with an average snowfall of just 4.1″ during January and an average precipitation of just 0.26″. However, this January has been exceptionally snowy across central/western Colorado as a series of moist, Pacific systems have impacted the high country, and the mountain valleys have been able to capitalize on this moisture as well. It will be interesting to see how much higher Alamosa’s snowfall total for January 2017 climbs through the end of the month.

A storm system on Thursday January 5, 2017 produced impressive snowfall amounts across southeast Colorado, with Pueblo and Alamosa both receiving record snowfall for the date. Pueblo picked up 6″ of snow at the NWS location, and Alamosa received 6.3″. These are two of the drier areas of Colorado during the winter months, but an arctic airmass combined with overrunning Pacific moisture and a powerful jet stream overhead combined to produce heavy snowfall bands across this region. The Sangre de Christo Range in particular picked up very heavy snowfall amounts, although reports are sparse in this rugged mountain range. Here are some of the snowfall totals reported spotters across southeast Colorado on January 5th.
- 10.7″ – Rye
- 9.0″ – Colorado City
- 7.6″ – NW Alamosa
- 7.2″ – Walsenburg
- 7.0″ – Westcliffe
- 7.0″ – Canon City
- 6.3″ – Alamosa
- 6.0″ – Pueblo (NWS office)
- 3.1″ – Colorado Springs Airport
