.DISCUSSION...

Idaho: Poor overnight humidity recovery tonight at mid to high terrain
slopes. A few thunderstorms are possible Wednesday afternoon through
early Thursday morning, however low wetting rain chances. Gusty outflow
as strong as 30 mph and isolated lightning possible. A mostly dry cold
front passes Thursday morning, followed by increased humidity and gusty
west winds through the remainder of Thursday. After breezy and mostly
dry days on Friday and Saturday, another very warm, dry high pressure
pattern re-emerges Sunday through much of the following week.

Montana: Poor overnight humidity recovery tonight and Wednesday night at
mid and high slopes. High Haines for west central and southwest Montana
expected Wednesday afternoon. Isolated nocturnal thunderstorms possible
mainly for Lolo and Bitterroot NFs Wednesday overnight. Cold front
passes through on Thursday, with a mix of wet and dry thunderstorms
producing more lightning strikes and wind gusts than wetting rain.
Humidity rises behind the front and breezy west winds will exist through
the weekend. Another warm and dry high pressure pattern for much of next
week.
