An upper level disturbance is moving inland today, bringing a pool of cold air to the higher levels of our atmosphere. This is going to make conditions slightly unstable, and allow for the development of scattered showers and isolated thunderstorms across the viewing area.
Most of the thunderstorm activity should be over Southern Oregon, excluding Curry County, but as of today the computer models brought the convection further south into Siskiyou County. For this reason, I have added isolated showers and thunderstorms to Northern California. As the sun rises, activity should begin developing and spreading in coverage through the afternoon.
A ridge of high pressure will then build into the region tomorrow and clear out sky conditions. Temperatures will continue warming through the weekend and into next week. An offshore flow is going to enhance the Chetco Effect and warm coastal temperatures into the upper 70′s and low 80′s through the weekend.
