.DISCUSSION...

Idaho: A weak disturbance approaching the area on Monday will bring an
increase in clouds and humidities and possibly a light shower Monday
evening into Monday night. Starting Tuesday, a gradual warming and
drying trend is expected through Friday as a ridge of high pressure
builds over the region. By Thursday/Friday temperatures will be in the
70s to low 80s for many areas with humidities in the upper 20s to low
30s. In the long term, models are hinting at a more active weather
pattern for next week.
