...DRY THUNDERSTORMS EXPECTED FOR CENTRAL OREGON TUESDAY, FOLLOWED
BY DRY AND WINDY CONDITIONS ACROSS THE KITTITAS VALLEY AND
WASHINGTON BASIN WEDNESDAY...

.The high pressure currently leading to hot and dry conditions
will start to break down Tuesday into Wednesday, allowing for dry
thunderstorms to develop across central Oregon. Once high pressure
has completely broken down on Wednesday, winds will pick up. With
RHs having little time to recover from Monday and Tuesday`s heat,
this will lead to potentially critical fire weather conditions
across the Kittitas Valley and into the Washington Columbia Basin.
