569 FXUS65 KGJT 081754 AFDGJT Area Forecast Discussion National Weather Service Grand Junction CO 1154 AM MDT Tue Sep 8 2026 .KEY MESSAGES... - Isolated showers, maybe a quick storm, will remain possible over the San Juans and along the Continental Divide through the week. - Temperatures will rise each day, remaining about 5 to 10 degrees above seasonal norms. && .DISCUSSION... Issued at 1018 PM MDT Mon Sep 7 2026 Drier southwesterly flow will gradually transition to more zonal flow by Wednesday as high pressure builds into the Desert Southwest. As a result, generally clear skies and warming temperatures will be the story for the coming week. There is a low (<15%) chance for an isolated shower or thunderstorm over the San Juans and Divide each afternoon. Temperatures will run 5-10 degrees above normal through the rest of the work week, with potential to drop back to near normal values over the weekend. Guidance is hinting at a potential moisture return at that point, as a trough moves into the Pacific Northwest and pushes the high to the east. However, agreement on this solution is still somewhat poor, so stay tuned if you have plans this coming weekend. In the meantime, enjoy the pleasant late summer/early fall conditions. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
