Fire Weather Planning Forecast for Wrn Montana and N Cntrl Idaho
National Weather Service Missoula MT
244 PM MDT Thu Jul 27 2017


.DISCUSSION...

Idaho: Scattered thunderstorms are expected today focused in the
southern Nez Perce-Clearwater NF and Bitterroot NF. Gusty winds 30 to 40
mph will be the main threat, and small areas under storm cores could
see brief heavy rains. Another plume of moisture will allow for
scattered wet thunderstorms Friday evening into early Saturday. This
weekend through next week, the ridge of high pressure strengthens,
leading to warmer and drier conditions. Expect lower afternoon RHs and
strengthening overnight thermal belts during this timeframe. Only
isolated, mostly dry showers look possible during the afternoons next
week.

Montana: Scattered thunderstorms are expected today focused in the
Bitterroot NF and Beaverhead-Deer Lodge NF. Some storms could reach as
far north as the Lolo NF, but confidence is lower here. Gusty winds 30
to 40 mph will be the main threat, and small areas under storm cores
could see brief heavy rains. Another plume of moisture will allow for
scattered wet thunderstorms Friday evening into early Saturday. This
weekend through next week, the ridge of high pressure strengthens,
leading to warmer and drier conditions. Expect lower afternoon RHs and
strengthening overnight thermal belts during this timeframe. Only
isolated, mostly dry showers look possible during the afternoons next
