SOUTHERN CALIFORNIA GEOGRAPHICAL AREA COORDINATION CENTER

RIVERSIDE, CALIFORNIA

***North winds expected over portions of Southern California this weekend***

***Gusty offshore winds likely Sunday night through Tuesday***

A weakening trough will move into the Pacific Northwest, which will spread a veil of high clouds across the area today. These clouds, along with light onshore flow, will allow for slightly cooler temperatures today and Saturday over much of the area. Despite this, temperatures will still be 8-12 degrees above normal with highs in the 50s in the mountains to the upper 70s to lower 80s in the interior valleys. Expect slightly higher RH the next couple of days, but some midslope areas will still see readings flirt with the 10-15% range this afternoon and again Saturday. The Pacific NW system will head inland Saturday, which will produce north winds of 15-25 mph with gusts to 35 mph over Santa Barbara County Saturday night. These winds will spread into the I-5 Corridor and the Cajon Pass Sunday. Surface pressure gradients will turn offshore Sunday night which will result in yet another round of offshore winds for the first half of next week. In general, winds will be lighter than last Monday and Tuesday, but some gusts to 40 mph will be possible in favored passes of Southern CA during the peak of the offshore wind event next Tuesday. Temperatures will be close to record high readings once again Monday through Wednesday and minimum RH will likely fall into the 8-12% range with poor nighttime recovery. Some relief from the heat is expected to arrive during the second half of next week when a compact low pressure area arrives. This system will likely bring rain to Central and Northern CA with a decent chance of light rain across Southern CA on Thursday. After this system departs, cool onshore flow looks to continue into the weekend of the 20th. END/RK
