Daytime highs ranged between 99 and 103 degrees on June 3 and between 102 and 106 degrees on June 4.

A large area of upper high pressure centered over the four corners region strengthened on June 3 and pushed an upper low off the southern California coast southwest and further away from the region. This resulted in a warming trend over the area as the mid and high level cloud cover which had been prevalent over the area during the previous few days eroded. High temperatures across the San Joaquin Valley and Sierra foothills were mainly between 99 and 103 degrees on June 3. The high remained the dominant feature over the area on June 4, and temperatures continued to rise with afternoon highs over the San Joaquin Valley and Sierra foothills mainly between 102 and 106 degrees. The high broke down and shifted east on June 5 while temperatures lowered to near normal levels as an upper level trough pushed into California.
