452 FNUS55 KBYZ 150905 FWFBYZ Fire Weather Planning Forecast for SCen and SErn Montana National Weather Service Billings MT 305 AM MDT Sat Jun 15 2024 .DISCUSSION... Warm temperatures will persist across the region today as minimum RHs drop into the mid 20 and 30 percent range. A cold front passage this evening will switch winds out of the northwest with 20 to 40 mph gusts common. Strong winds will also impact the mountains this afternoon/evening with gusts into the 40s and 50s (mph). While chances of wetting rain remain low today, isolated to scattered showers and thunderstorms are possible once again. This activity may create erratic winds, brief heavy rain, and frequent lightning. The strongest storms are expected over eastern districts. A pattern change to cooler and wetter (with better chances of wetting rain) look to return early next week.
