    Monsoon Season Begins in New Mexico, Southern Rockies

    4 days ago Alan Smith

    An early season surge of monsoon moisture will result in numerous thunderstorms and flash flooding potential across New Mexico on Tue & Wed. Colorado & Eastern Wyoming will also see an uptick in showers & t-storms, especially on Tue with stronger storms capable of large hail & damaging winds. Later in the week, CO will see a reduction in storms while New Mexico will continue to be favored.

    A Ho-Hum Summer

    21 days ago Matthew Platt

    Well..... it's finally here. The most unfortunate time of year with no snow and no prospects of any snow in the future. These days, I catch up on housework, travel a lot, and sneak a peek at the models once a month. The extended Euro model was just released, and the latest ENSO forecast is interesting. Let's dig in because what else is there to do this time of year?!

    Final Post of the 2024-2025 Season

    2 months ago Alan Smith

    The winter of 2024-2025 featured near to above average snowfall across the Sierra, Central/Northern Rockies, and much of the East. Snowpack is currently melting at a faster rate than usual across much of the West due to warmer and drier conditions so far in April. Looking ahead, a storm will bring high-elevation snow showers to the Sierra & the Rockies from late this week through early next week.

    Final Post of the 2024-2025 Season

    2 months ago Powderchaser Steve

    This will be my final chase powder post for the 24/25 season. It has been an epic season in many areas, including northern Vermont and many northern/Central Rockies, Sierra, and Alaska spots. La Niña delivered as forecasted. Next Season will be deep somewhere! It is always deep on the Chase Powder Forecast. This post recaps the season for 24/25.
