The ridge that brought as a sunny and warm Summer day will push east as a cold front moves in tomorrow. This front will bring moderate to heavy rainfall at times, gusty winds, thunderstorms, small hail, high seas and even some wet snow at times above 6,500 feet. The heaviest rain will fall at the coast and Cascades, this is a very typical fall storm system. The coast will start to see a few sprinkles in the morning with rain arriving by 11am on Friday then spreading inland in the late afternoon with a chance for thunderstorms; the best chance for thunderstorms on Friday will be at the coast and offshore with a better chance for inland areas on Saturday. The Basin looks to be dry on Friday with increasing clouds and winds, gusts potentially up to 40 – 50 mph, and thus a Red Flag Warning has been issued from noon to eight Friday night for these winds and dry conditions.
There will be a break in the rain Saturday evening into Sunday early afternoon before the next front arrives bringing more rain and gusty winds Sunday evening. This second system will hit southern Oregon more so than northern California, but most areas will see at least some spotty showers into next week.
With the passing of each front not only will we see rain, but also dropping temperatures. Friday will be about 10 degrees cooler than Thursday with another ten degree drop on Saturday! Temperatures will remain unseasonably cool into next week; just as Fall begins on Sunday it will feel like it!
Thanks for logging on and have a great evening!
