...DRY THUNDERSTORMS EXPECTED TUESDAY OVER CENTRAL AND EASTERN OREGON, FOLLOWED BY DRY AND WINDY CONDITIONS ACROSS THE COLUMBIA BASIN WEDNESDAY... .The ridge of high pressure currently in place over the Pacific Northwest will break down Tuesday night through Wednesday as a pair of upper-level low-pressure systems pass over the region. This will lead to thunderstorm development across central and eastern Oregon Tuesday afternoon and evening. Widespread breezy to windy conditions will persist Tuesday evening through Wednesday, strongest through the Cascade gaps and Columbia Basin. * AFFECTED AREA...Fire Weather Zones 696 John Day Valley, 700 Central Mountains of Oregon and 705 Southern Deschutes National Forest. * TIMING...From 2 PM to 11 PM PDT Tuesday. * IMPACTS...Any fire that develops will catch and spread quickly. Outdoor burning is not recommended. * THUNDERSTORMS...Storms are mostly expected to be dry with rainfall amounts less than a tenth of an inch, though a few storms could produce rainfall amounts in excess of a tenth of an inch. * OUTFLOW WINDS...As high as 60 mph.
A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
