California weather is heating up fast across the San Joaquin Valley this afternoon as bright sunshine bakes fields surrounding Hanford and Lemoore. Dry air and steady northwest breezes swept across Highway 198 late this morning while temperatures climbed through the upper 80s. The warmup feels more like early July than late May across central California.
According to the National Weather Service, sunny skies will continue through the afternoon with highs reaching near 89 degrees around Hanford Municipal Airport. Northwest winds remain relatively light today, but gusts could increase to around 20 mph by Tuesday night as another Pacific weather system brushes the West Coast. Despite the breezier pattern, dry conditions remain firmly in place across much of the Central Valley.
Memorial Day stays hot and sunny with temperatures hovering close to 88 degrees across Hanford, Visalia and Tulare. Tuesday cools slightly into the lower 80s before midweek temperatures stabilize near seasonal averages. To be fair, desert communities farther south and east continue pushing well into the 90s and lower 100s through early next week.
Drivers traveling through the valley should stay alert for occasional crosswinds on exposed stretches of Highway 198 and Interstate 5 Tuesday night. Dry grass and low humidity may also elevate localized fire concerns near rural roads and open fields during the warmest afternoons.
The broader western United States remains unusually warm and dry through Memorial Day under a strong ridge of high pressure. However, a Pacific system arriving in the Northwest later Monday into Tuesday may slowly cool portions of California by midweek while increasing mountain shower chances farther north.
Long-range outlooks continue signaling above-normal temperatures into early June across central California, reinforcing a strong early-summer pattern across the San Joaquin Valley.
