Hot and dry conditions will dominate the weather for the next
several days, with a slight moderation in temperatures tomorrow
and Thursday. A shift to breezy northwesterly winds will occur
over most of the region tomorrow afternoon, otherwise winds will
be light and diurnally driven. There is a 10% chance of an
afternoon thunderstorm or shower in Eastern Payette National
Forest tomorrow afternoon, but confidence is low. A significant
pattern shift is on the way for this weekend, with scattered
showers and thunderstorms anticipated with a monsoonal push.
