A large area of high pressure built into California on May 25 and May 26. This resulted in much above normal daytime temperatures on both days with some locations setting new daily records on May 26. The high then strengthened on May 27 and May 28 resulting in widespread record heat over the region on both days with highs in the San Joaquin Valley mainly between 103 and 107 on both days. Triple digit heat was also observed across portions of the Sierra foothills and Kern County Deserts. Temperatures cooled by several degrees on May 29 and lowered to below seasonal averages by May 30 as the large area high pressure broke down, and a cold front pushed through the area.
