.DISCUSSION...

Idaho: Showers will continue to pass through north-central Idaho until
around 1000-1100 MDT, ahead of the cold front, and there may be a few
lightning strikes this morning as well. Wetting rains are possible but
widespread wetting rains are unlikely today. Wind will increase with the
cold front this afternoon and there will be additional thunderstorm
chances mainly south of Highway 12. Humidity will not be as dry as
previous days with increasing moisture in the region, but Friday will
again see lower humidity and increased winds behind the cold front. Warm
and dry conditions with strengthening thermal belts return for Saturday
under high pressure that should remain into next week.

Montana: Showers will pass through western Montana until around
1200-1300 MDT, ahead of the cold front, and there may be a few
lightning strikes this morning as well. Wetting rains are possible, with
highest chances being in northwest Montana, but widespread wetting
rains are unlikely. Wind will increase with the cold front this
afternoon and there will be additional thunderstorm chances mainly south
of Highway 12. There are indications that lightning activity will
increase this afternoon in the Beaverhead/Deerlodge and stronger storms
will produce gusty winds. Humidity will not be as dry as previous days
with increasing moisture in the region, but Friday will again see lower
humidity and increased winds behind the cold front. Warm and dry
conditions with strengthening thermal belts return for Saturday under
high pressure that should remain into next week.
