SPOKANE A Red Flag Warning has been issued by the National Weather Service for critical fire weather conditions from Wednesday through Friday in most of Eastern Washington.
The affected area is mostly north of Interstate 90, although some areas to the south are included. It extends into the Idaho Panhandle.
The Weather Service said a thermal weather system is migrating through the region and will bring dry and unstable conditions to the Cascades and northern mountain districts Wednesday. Breezy conditions will develop Wednesday evening through the Cascade gaps and spread across the region on Thursday, bring continued warm conditions and low relative humidity.
On Thursday night, a cold front is expected, but will bring wind and a chance of thunderstorms over the northern mountains, meteorologists said.
Winds are expected to be from the southwest at 10-15 mph with gusts up to 25 mph on Thursday and from the west to northwest at 15-25 mph with gusts to 30 mph on Friday, meteorologists said.
Isolated to scattered wet thunderstorms are possible, especially near the Canadian border. The Weather Service said the potential for thunderstorms is less certain than the wind forecasts.
The warning runs from 11 a.m. Wednesday to 5 p.m. Friday.
