The upper level disturbance that has brought thunderstorms to the region the past week is now lifting north and east. This has significantly reduced cloud cover and warmed temperatures up across Southern Oregon more so than Saturday. The warming trend will continue into the middle of the week. The thunderstorm threat has been extended into Monday due to some lingering instability and moisture that will wrap around the back end of the disturbance exiting the region. The best chance for these storms will be along the Cascades, the East Side and Siskiyou County Monday afternoon and evening.
Another cut off low will emerge towards the middle of the week, and combine with the disturbance that is just now moving north. It will sit off the coastline and possibly bring some light sprinkles to coastal sections Thursday, and thunderstorms back to parts of the Klamath Basin and higher terrain into Friday.
The recent rains have dramatically improved air quality, but this will not be the case through the week. With rain showers gone, and fairly calm winds, smoke will gradually infiltrate further inland, south and east of the fires through the week.
