A potent low pressure system will bring rain & t-storms to Montana & the Northern Rockies on Tue, while monsoon moisture will favor t-storms in CO & NM from Tue to Thu. Heading into the weekend, the monsoon will weaken significantly as dry air arrives, leading to a reduction in t-storm activity & rain potential. Next week, the monsoon will gradually rebuild.

Showers and thunderstorms may be present throughout the region starting tomorrow, Saturday, through the middle of next week. Temps will cool off early next week before trending back up towards seasonal values, the middle of next week. Summer will likely be in full swing by the 2nd weekend of June.

It's April 30th, and the last post of the 2024-25 season. I'll give some final season snowfall and precipitation stats, and we'll look forward to next season, which will start during the fall of 2025. My 20th season forecasting for the Sierra!

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.

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.
