Area Forecast Discussion National Weather Service Hanford CA 216 AM PDT Wed Aug 14 2019 .SYNOPSIS... Widespread triple digit heat will continue in the San Joaquin Valley through Friday with the hottest day being Thursday. Temperatures will drop to near normal this weekend before trending back upward early next week. Dry weather will persist across Central California through at least the next seven days. && .DISCUSSION... A ridge of high pressure will continue to strengthen over the region today and Thursday bringing clear skies and warming temperatures. Temperatures rose into the triple digits many areas of the San Joaquin Valley Tuesday, and expect all areas of the Valley to be in the triple digits today. As the ridge continues to strengthen, temperatures will warm even a few more degrees Thursday, which is expected to be the hottest day of the week. Temperatures will be 5-10 degrees above normal across the entire central California interior on Thursday. The excessive heat warning remains in effect for the San Joaquin Valley and Westside Hills Thursday with a heat advisory for the Sierra Foothills. With Wednesday and Friday being almost as warm, will continue with the heat advisories for the San Joaquin Valley and Westside Hills for those days. Friday night and Saturday, a trough of low pressure deepening along the west coast will weaken the ridge slightly and allow some marine cooled air to spill into the San Joaquin Valley. Thus, temperatures will cool back to normal for Saturday and cool a few more degrees Sunday. The cooler temperatures will not last long as the ridge of high pressure begins to build right back into California early next week, warming temperatures back toward 100 by next Wednesday. With no influx of moisture into the region, the forecast remains free of precipitation for at least the next seven days.
