Weekend Mountain Weather update; Early June Looking Wet

Tomer’s Take: Forecast freezing levels stay elevated. This forces the snowpack to continue melting across the West. I’m also forecasting afternoon thunderstorms almost every single day across the Intermountain West with a rich feed of moisture. Early June could be wetter than normal.

11:30am view from Vail looking East/Northeast across the Gore Range. Snow continues melting and you can see the daily thunderstorms developing.

Rich Moisture Feed

Afternoon thunderstorms are likely each day through the end of May. This pattern will likely continue into early June and of course July-August.

In addition, we’re seeing extra moisture flood the atmosphere over the Intermountain West making afternoon thunderstorms even more likely.
