Monday Night through Saturday...Early portion of the medium range
period continues to look dry, with warm days and cool nights through
Wednesday. This return to summer like weather will be courtesy of an
upper level ridge as it progresses through the Northern Rocky
Mountains. Wednesday night into Thursday will be a period of
transition as an upper level trough sweeps eastward through the
Pacific Northwest and into the Northern Rocky Mountains.
Temperatures are expected to remain above seasonal averages but
there will be an increasing chance for showers and possibly a
thunderstorm, especially in Southwest Montana and along the Rocky
Mountain Front. The trough will be over the state on Friday for
cooler temperatures and a continued slight chance for
precipitation.  Trough moves east of the forecast area by Saturday
for a slight rebound in temperatures with isolated mountain showers
lingering over the region. mpj
