Tonight: A weak disturbance moves overhead increasing instability across Oregon. For that reason there is a slight risk of dry lightning today with lows in the mid 50s. When you combine the risk of dry lightning and the already very high fire danger, any strike could spark a fire. For that reason the National Weather Service has extended the Red Flag Warning until midnight tonight.
Tuesday: Mostly cloudy skies with slightly cooler highs in the mid to low 80s. Smoke and haze will also linger through the inland valley keeping air quality in the moderate range.
Wednesday-Friday: A stronger system arrives by the middle part of the work week bringing in a chance of rain (20-30%), strong westerly flow and even some fall like temperatures in the upper 70s to low 80s. The chance of rain and stronger onshore flow will help in decreasing fire danger but also pushing a good amount of smoke out of the valley. Hoping to see better air quality by this time.
Saturday-Monday: Drier and sunny conditions return for the last weekend of summer. Highs will warm up gradually into the upper 80s to low 90s with only a slight 10% chance of rain.
Remember the Fall officially begins Monday, September 22nd at exactly 7:29pm! Hope you can get out and enjoy the last few days of Summer!
