Wider weather episode

A large high pressure ridge strengthened off the California coast on June 22 and slowly built inland through June 24 providing the San Joaquin Valley with it's first prolonged period of triple digit heat in 2018. As a result of the widespread triple digit heat in the San Joaquin Valley during this period, several municipalities opened cooling centers during the afternoon hours. The ridge weakened and moved east of the area on June 25 allowing for cooler air to push into the San Joaquin Valley and end the hot spell.
