Central California is set to experience a gradual cooling trend this weekend, with temperatures expected to return to near-normal levels by Monday, according to the National Weather Service (NWS) in Hanford. The region has been under the influence of a weakening high-pressure ridge, which will continue to bring hot temperatures through Sunday, with highs ranging from 102 to 105 degrees Fahrenheit in the Valley.

Kern County's desert areas could see temperatures reach up to 110 degrees, while Merced and Madera Counties have a 67-85% probability of hitting 100 degrees through Saturday. The rest of the San Joaquin Valley has a 60-90% chance of triple-digit highs until Sunday afternoon, with the Coastal Range experiencing similar probabilities.

However, as a trough from the Pacific moves in, temperatures will start to decrease daily, with a significant cooling trend expected from Monday onward. The NWS projects that by Monday, the likelihood of temperatures reaching 100 degrees will drop to 20-40% north of Fresno, and south of Fresno by Tuesday. By midweek, temperatures could fall to 95 degrees or lower across the Valley, with a 30-60% probability.

While the cooling trend is welcome, the NWS also warns of elevated fire risks due to moderate humidity levels and increased winds, particularly on Saturday and Sunday. The potential for grass fires remains a concern, especially with stronger winds expected in the afternoons.

Looking further ahead, the weather pattern remains uncertain. One possible scenario suggests the continuation of near-normal or below-normal temperatures, while another, less likely scenario could bring moisture and the potential for dry thunderstorms, increasing fire risks.
