The Western Slope can expect less hot temperatures, increasing clouds and more daily storms.
The average high temperatures for Grand Junction is 93F. The forecast doesn’t expect to achieve those averages until late week/late weekend. Until then there will be increasing chances for late day storms. The pattern is allowing more of a southerly subtropical storm influence and this is great for our wildfires, but not so great for burn scars and areas that get brief heavy downpours. Tough to pinpoint the exact location of storms, but they will be widely scattered, daily and should put down measurable rain, gusty winds along with lightning and flooding.
If you are travelling I-70 this week, pay close attention to the Glenwood Canyon section/Grizzly Creek burn scar. More closures will be possible for mud/debris flow. Any burn scar could slide with heavy downpours and more debris flows from (non burned) steep narrow roadways are also possible this week.
