July 27, 2019 - The National Weather Service Hanford Office reports high temperatures this weekend will rise well into the triple digits, or around 105 to 110 degrees, at many locations, especially in the San Joaquin Valley and the Kern County desert areas.
Plan to take action to reduce time outdoors, drink plenty of water, and remain in air-conditioned buildings.
Heat-sensitive groups, such as the elderly, young children, and those with chronic ailments may need assistance to avoid heat-related illness.
As always, never, ever leave a child or pet in an enclosed automobile.
Area Forecast Discussion National Weather Service Hanford CA 220 AM PDT Sat Jul 27 2019 .SYNOPSIS... A large area of high pressure will maintain widespread triple digit heat across the San Joaquin Valley, West Side Hills and Kern County Deserts through Monday. The peak of this heat should occur this weekend. Temperatures trend back to normal beginning Tuesday. && .DISCUSSION... High pressure remains in firm control over the region with hot temperatures continuing through the weekend. The ridge has shifted farther west, with the flow aloft west-southwesterly. This has pushed the monsoonal moisture eastward. Thus, do not expect to see any more thunderstorms, but could see a few cumulus buildups over the higher elevations of the Sierra Nevada today. Dry weather is expected the rest of the 7 day period. Temperatures will remain in the triple digits across the San Joaquin Valley, the West Side Hills, and the Kern Desert areas through Monday. A heat advisory remains in effect for this afternoon and evening. For now will continue with the excessive heat watch for Sunday as models have been fluctuating between an advisory and a warning. Will let the day shift assess. On Monday, 500mb heights begin to decrease slightly as the ridge axis gradually shifts eastward again and a trough of low pressure forms along the west coast. This will allow temperatures to start edging back down next week. The widespread triple digits will remain Monday, then temperatures will be near normal Tuesday through next Friday.Source: NWS
