The National Weather Service in Hanford, CA, has issued its latest area forecast, predicting a significant rise in temperatures across the San Joaquin Valley this weekend. Today, residents can expect temperatures to exceed the climatological averages, with probabilities ranging from 60 to 90 percent for highs in the lower 80s. Sunday will see slightly lower probabilities of 30 to 65 percent for above-average temperatures.
Along with the rising heat, low afternoon relative humidity is expected, resulting in poor to moderate overnight recoveries, especially in mountainous and desert regions.
A low-pressure system passing to the north will bring a slight chance of precipitation to the San Francisco Bay Area and northern regions today, but the San Joaquin Valley is likely to see only increased cloud cover without significant rainfall. However, a return to more seasonal temperatures is anticipated for Sunday before highs rise again on Monday, with probabilities for maximum temperatures of 85 degrees reaching 45 to 85 percent in the Central Valley and Kern County desert.
