Chief Meteorologist Justin Stapleton‘s Nightly Forecast Discussion: 

**Wildfire information: Oregon Wildfires ***

Tonight, all is quiet and still muggy with the upper low spinning offshore and thunderstorms well off to the east end of the state. Lows tonight, once the low clouds fill in, will sit in the low 60s and upper 50s. Tomorrow starts a string of a couple of days of unstable weather across Western Oregon. The sunshine we see early in the afternoon, will be replaced by clouds from developing thunderstorms in the mountains. Highs will climb into the low to mid 80s.

Wednesday night and Thursday, the mountains have a good chance of seeing some isolated, yet, strong thunderstorms. With the low providing lift, the jetstream sucking in moisture off the ocean, and some good daily sunshine, that’s a recipe for some widespread development late Wednesday and certainly most of the day Thursday. Any thunderstorm that gets going will carry threats of hail, gusty winds, heavy downpours and certainly frequent lightning. As the winds turn more to the SE, some cells may try to slide into the valleys late Thursday. Even if they don’t we’ll still see a good chance at passing showers on and off through most of the day into Friday morning.

By the weekend, high pressure moves back in as the low swings into Washington, putting Western Oregon under sunny skies by Saturday and highs jumping back up into the low to mid 80s.

Have a great Wednesday!
