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.

June was a very dry month across Western Wyoming, but the first few days of July will be more active as the first monsoon moisture surge of the season arrives. Moisture will arrive at the mid-levels of the atmosphere initially with mainly dry t-storms (light rain, gusty winds) on Tue & Wed followed by more numerous storms with heavy rain possible Thu-Fri as deeper moisture arrives.

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.
