Fire Weather Planning Forecast for Wrn Colorado and Ern Utah
National Weather Service Grand Junction CO
1254 PM MDT Fri Sep 11 2026

.DISCUSSION...Localized critical fire weather conditions are 
expected today due to gusty winds and low RH. This weekend, gusts 
upwards of 35 mph are forecast for much of the area. However, an 
influx of moisture will negate the potential for widespread 
critical fire weather conditions due to rising RH. Temperatures
will be above normal through this weekend with cooler, unsettled
weather arriving next week due to a steady influx of moisture.
