333 FNUS55 KBYZ 010804 FWFBYZ Fire Weather Planning Forecast for SCen and SErn Montana National Weather Service Billings MT 204 AM MDT Fri Aug 1 2025 .DISCUSSION... Unseasonably moist pattern continues heading into the weekend. Persistent easterly winds will keep plains moisture in place holding afternoon RH values well above normal, and producing strong recoveries at night. A chance of wet thunderstorms are in the forecast each afternoon and evening through Saturday, with some activity holding on through the overnight hours. Conditions begin to slowly dry out Sunday through the middle of next week as the easterly winds become less consistent and drier westerly winds develop at times. That said, no significant fire weather patterns are in the forecast through next week.
