846 FNUS55 KGGW 122037 FWFGGW Fire Weather Planning Forecast for Northeast Montana National Weather Service Glasgow MT 237 PM MDT Sat Jul 12 2025 ...RED FLAG WARNING IN EFFECT UNTIL 8 PM MDT THIS EVENING FOR LOW RELATIVE HUMIDITY AND BREEZY NORTHWEST WINDS FOR FIRE WEATHER ZONE 134... .DISCUSSION... Upper level ridging is guiding hot and dry conditions across the region today. West winds this afternoon will eventually become north to northwest at 10 to 20 mph with occasional higher gusts as relative humidity bottoms between 15 and 20 percent for most areas. This combination will lead to critical fire weather conditions across portions of Phillips and Valley Counties or Fire Weather Zone 134 where a Red Flag Warning remains in effect. Elevated fire concerns will still exist outside of the warning area but true critical conditions will be more isolated and less persistent. Elevated fire weather concerns may result on Sunday as well with hot and dry conditions but wind speeds may be somewhat lighter.
