231 FNUS55 KMSO 211105 FWFMSO Fire Weather Planning Forecast for Wrn Montana and N Cntrl Idaho National Weather Service Missoula MT 505 AM MDT Thu Jun 21 2018 .DISCUSSION... Idaho: Thunderstorms this morning will be most prevalent across the North Fork district, but as the day progresses, more widespread thunderstorm development is expected to occur and impact all forests in north central Idaho. By this afternoon, storms may grow strong enough to produce hail of various size, in addition to abundant lightning, heavy rain, and gusty outflow winds. Given how unstable the atmosphere is, expect all day to be plagued by some form of thunderstorm impact. Montana: Isolated thunderstorms will cross west central Montana districts this morning, with more widespread coverage of thunderstorms occurring later this afternoon through this evening. Thunderstorms could become strong to isolated severe across the Beaverhead/Deerlodge by mid-afternoon today. Hail and damaging winds will be the biggest threat.
