As a trough of low pressure digs through the Great Basin, high pressure will build in supporting another offshore flow with gusty Santa Ana winds expected over the weekend. Cold air advection will bring colder temperatures and strong winds below passes and canyons. Expect mostly clear skies through Friday with highs in the mid 50's, westerly winds 5-10 mph. Winds turning northerly Friday night under clear skies as lows drop into the mid to lower 20's. The offshore flow will strengthen Saturday with northeast winds 10-20 mph at times, gusts over 60 mph are possible below passes and canyons, all the usual wind prone locations. Daytime temperatures will drop into the lower and 40's Saturday, climbing back into the 50's Sunday as the offshore flow weakens. The onshore flow will return early next week followed by another offshore flow towards the middle of the week as our forecast remains dry, for now.
