Fire Weather Planning Forecast for Wrn Colorado and Ern Utah
National Weather Service Grand Junction CO
111 AM MDT Mon Jul 27 2026

.DISCUSSION...Little noticeable change to the forecast as hot
temperatures remain along with daily thunderstorm chances. The
moisture driving the thunderstorms is sufficient enough to limit
critical fire weather and overall light winds are expected under
high pressure aloft. Burn scars will remain susceptible to debris
flow and flash flooding as the atmosphere will support moderate
to heavy rainfall rates. 

...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
