Monsoon moisture will increase across the Southwest & the Rockies this week, leading to a notable increase in thunderstorm activity. The Southwest & Southern Rockies will be most active Tue-Thu, while the Northern Rockies will see an uptick from Thu to Sat. Next week, a more seasonal early monsoonal pattern will settle in across the Southwest & CO Rockies while most of the West will heat up.

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.
