An upper level disturbance is continuing to filter cloud cover into the region, but despite the cloud cover, today is going to be fairly quiet and dry. The high temperatures will be similar to those from Monday. Because there is an onshore flow, you can’t rule out some light showers along the Coast but also for inland areas due to higher terrain. Any showers that do develop will not amount to anything.
The upper low begins weakening Wednesday but will begin moving inland through the overnight hours. For these reasons, clouds will be increasing across the region Wednesday afternoon and evening. By Thursday, enough moisture and just enough instability should support spotty showers across Southern Oregon. Thunderstorms will only be a threat for the Klamath Basin and Southern Cascades, Siskiyou County on the other hand will just see cloud cover.
A ridge of high pressure will build in following the lifting of this upper level low. Clearing skies and warming temperatures will move into place over the region, and an offshore flow is going to bring temperatures along the Coast into the mid and upper 70’s.
