Description

...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. The National Weather Service in Pendleton has issued a Fire Weather Watch for wind and low relative humidity, which is in effect from Wednesday afternoon through Wednesday evening. * AFFECTED AREA...Fire Weather Zones 690 Kittitas Valley and 691 Lower Columbia Basin of Washington. * TIMING...From Wednesday afternoon through Wednesday evening. * IMPACTS...Any fire that develops will catch and spread quickly. Outdoor burning is not recommended. * WINDS...For the Kittitas Valley, northwest winds 20 to 30 mph with gusts up to 40 mph. For the Lower Columbia Basin of Washington, west-northwest winds 15 to 20 mph with gusts up to 30 mph. * RELATIVE HUMIDITY...As low as 15 percent.
