National Weather Service Grand Junction CO
809 PM MDT Sat Aug 9 2025
.DISCUSSION...Winds will trend downward on Sunday leaving mainly
localized areas of critical fire weather with the greatest threat
over the Four Corners area of SW Colorado due to the northwest
winds aloft. High pressure builds to the west this coming week
with continued hot and dry conditions although less windy so
critical fire weather conditions appear more localized.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
