.KEY MESSAGES...
- Temperatures continuing 5 to 10 degrees above normal through
  Thursday.

- Slight chance of thunderstorms over higher terrain Wednesday
  and Thursday afternoons with gusty outflow winds but little,
  if any, rain.

  much cooler air lasting through Monday. Snow possible as low

&&

.SHORT TERM /Through Thursday Night/...
A weak upper ridge will maintain hot weather through Thursday
with enough instability for isolated high-based afternoon and
evening thunderstorms. Storms will produce gusty outflow winds
but little, if any, rain. A strong north Pacific cold front
will pass through eastern Oregon pre-dawn Friday, beginning a
change to wetter and much cooler weather.

&&

.LONG TERM /Friday through Tuesday/...
A closed upper low will steer into the northwest region from off the
coast of British Columbia on Friday. This pattern will bring a cold
front through southwest ID on Friday with cooler and unsettled
conditions through Saturday and Sunday. Widespread showers and
thunderstorms are expected throughout Friday with this frontal
passage, with the highest chances in the afternoon. There is
slightly better guidance agreement over the upper low center
moving right over our area on Saturday. As such, Saturday and
Sunday will see the highest chances of wetting rain, mainly over
the west-central ID mountains, with temperatures as much as
20-30 degrees below normal area-wide. With snow levels expected
to drop down into the 6000-7000 ft MSL range by early Sunday,
light snowfall remains possible on mountain peaks late Saturday
through Sunday morning. Conditions dry out with breezy
conditions on Monday and Tuesday as the system moves northeast
into west-central Canada. Our area will likely stay under a
drier shortwave trough behind the system and remain in a cooler
pattern from a northwest flow early next week.
