Yesterday’s disturbance has weakened and died out, but the remnants of the shower activity still lingers across the viewing area. For this reason, the morning has gotten off to a mild and similar start to Wednesday morning. Cloud cover will gradually break up and decrease in coverage by midday. By late afternoon though it will begin building up again. We are still seeing a fairly unstable, and hot, air mass in place. A second disturbance to our South and West will continue the thunderstorm threat today over Siskiyou County.
The thunderstorm potential today is not as high as yesterday, however is still worth mentioning. Most of the Klamath Basin should catch spotty showers today rather than thunderstorms, so I have left dry thunderstorms out of the forecast there. The best chance for any thundershower activity is going to be over Northern California. Light sprinkles may fall in the Rogue Valley and along the Coast, but none of the showers should really amount to much.
Thunderstorms are still possible tomorrow (in Siskiyou County) as we have one last day with the moisture and heat present. Come the weekend, temperatures are going to begin dropping as a trough settles into the NW. This is going to bring temperatures back to seasonal values by Sunday–about 10 degrees cooler than this past week. Cooler temperatures will linger into next week, and clear skies will continue to bring sunny conditions.
