Expires 3:00 PM EDT on September 03, 2015


... Unseasonably cool temperatures leading into the weekend...

An early autumn like weather system is settling over the region
and will remain through the beginning of the Labor Day weekend.
This will lead to unusually cool conditions through this period
with high temperatures in the Columbia Basin in the upper 60s to
mid 70s while the mountains will see 50s and 60s. Overnight low
temperatures will also be cool with 40s in the basin and upper 20s
and 30s in the mountains.

A cold front will be slow to exit the region overnight and early
Thursday bringing a chance of precipitation to the far eastern
mountains. The best chance for a more widespread rain will come
Friday and Saturday as The Heart of the cold air moves over the
forecast area. Precipitation totals of a quarter to half an inch
will be possible with some mountainous areas receiving up to an
inch. Snow levels during this time will lower to around 6500 feet
which means there could be a dusting of snow in the higher
elevations of the Wallowa, Elkhorn, Strawberry and Cascade
mountains.

Those planning outdoor adventures should be prepared for the
cooler conditions and the precipitation.
