698 FNUS55 KGJT 200906 FWFGJT Fire Weather Planning Forecast for Wrn Colorado and Ern Utah National Weather Service Grand Junction CO 306 AM MDT Wed Aug 20 2025 .DISCUSSION...Hot and dry conditions will continue through Friday, with highs 10-15 degrees above normal. Winds remain light, keeping chances for critical fire weather conditions very low. However, moisture starts to increase tomorrow, increasing coverage of showers and thunderstorms over the terrain. It will take several days for the surface air to moisten enough for wetting rain, meaning concerns for dry lightning through the end of the week. Better chances of wetting rain start Saturday and linger into early next week. ...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS OR THUNDERSTORMS... ...THE SMOKE DATA IS CALCULATED FROM AN AVERAGE AT 6000 FEET MSL...
