The strong upper ridge which built inland into California during the Memorial Day holiday weekend remained in place over the region on June 1 and June 2 resulting in temperatures approaching record levels across the San Joaquin Valley, the West Side Hills and the southern Sierra foothills on June 1 and 2. Several stations across these areas had maximum temperatures exceeding the century mark on June 1 and June 2 prompting the continuation of Excessive Heat Warnings and the opening of cooling centers due to this event taking place early in the season. The near record heat heat continued in the Bakersfield area on June 3 and several stations in the Kern County Deserts had highs near 110 on June 2, June 3 and June 4.
