Fire Weather Watch is up for most of Western Montana Monday afternoon into early Monday evening. Monsoonal moisture moving up from the south is expected to produce a few thunderstorms Monday afternoon. The lower levels of the atmosphere are very dry and thus there is a good chance that most of the thunderstorms tomorrow will be dry, producing gusty outflow winds and numerous lightning strikes on top of extreme heat and very dry fuels.
Outflow winds around some of these thunderstorms could gust up to 20 to 30 mph at times. Humidity values between 15%-25% meaning extremely dry surface air and frequent lightning are the ingredients for the fire weather watch.
Some thunderstorms could produce brief heavy rain, however, prepare for possible dry storms tomorrow. Although there are no watch/warnings for the Bozeman area dry thunderstorms are possible there as well.
I'll have the latest forecast for SW Montana tonight at 5:30pm and 10pm.
