Spring Transition in the Mountains

Colorado’s snowpack starts melting in April and reaches maximum melt around the clock in May and June.  Expect pauses in the melting as weekly storm systems move through Colorado with colder air and new snow.

Spring couloir season peaks in late April, May, and early June.  Overnight freezes become less likely by mid-May.

Approaches that are covered in snow are often frozen and firm in the morning and then turn into post-holing nightmares in the afternoon.

Spring Forecast

April experienced some of the windiest weather on record.  The jet stream followed La Nina architecture and sat over Colorado.  The latest forecasts suggest La Nina continues all spring and summer.  Normally, winds above tree line start to drop quickly in May and reach seasonal minimums in June, July, and August.  I expect windier than normal conditions to continue this May and June.  I also expect snowier than normal conditions in May across the Central and Northern Mountains.

  • May: Windier and snowier than normal Central and Northern Mountains.

  • June: Windier than normal Central and Northern Mountains.

Afternoon Thunderstorms

Afternoon thunderstorms normally start by Memorial Day.  Plan on afternoon thunderstorms in June, July, and August.  Violent afternoon thunderstorms peak in July and August with the seasonal monsoon.

June often has periods of strong high pressure.  This can preclude afternoon thunderstorm chances for short periods.  The old adage of summiting by noon works well under most circumstances.

Wildfire Smoke

The last few summers have featured thick wildfire smoke.  I think the odds of a replay are high this summer and especially high this fall.

Gear Needs

You’ll need an extra layer in May and June if this forecast verifies.  If the pattern stays active most of May, then we’ll likely add cooler than normal mountain temps additional snow into the mix.  Some peaks might require traction and gaiters into June.

This promises to be the busiest summer on record in Colorado’s mountains.  More technical routes in June may hold snow.  Know your limitations. 

Study routes and weather before arriving at the Trailhead.  Don’t count on cell phones.  Service and batteries die when you need them most.

I'm a weather nerd, so I appreciate this post. For anyone in the southwest part of CO, I recommend the Durango Weather Guy's blog. Boo for wind. Let's hope for a healthy monsoon season, even though it increases my chances of getting caught in an afternoon electrical storm above treeline during summer mountain ultras.
