Sacramento Weather

Northern California is still dealing with dangerous heat, but the hottest stretch is expected to ease by midweek. The National Weather Service says temperatures should trend back toward seasonable levels by the weekend. Until then, much of the Central Valley remains under heat alerts, and some mountain areas may see thunderstorms later in the week. Those storms could bring lightning, brief showers and gusty winds in isolated spots. Where the Heat Is Hitting Hardest The National Weather Service said extreme heat will affect portions of Northern California and the Central Valley through Tuesday. In the northern Sacramento Valley, some of the region’s highest readings are expected, with Redding near 109 degrees and Red Bluff around 107 degrees. Chico could reach 104 degrees, while cities including Sacramento, Modesto, Merced and Fresno are also expected to stay hot. Those locations remain under a heat advisory through 11 p.m. Tuesday, June 16. “These hot temperatures combined with low relative humidity and breezy onshore winds, will lead to elevated fire weather conditions in the northern Sacramento Valley and adjacent terrain through Tuesday,” the National Weather Service said.

Merced and Fresno are also expected to feel the peak of the heat before conditions gradually improve later in the week. Merced’s hottest temperatures should arrive Tuesday and Wednesday, while Fresno is forecast to top out around 101 degrees on Tuesday. Thunderstorms Could Return To The Sierra Nevada As the Valley heat starts to ease, the Sierra Nevada may see a more active weather pattern. The National Weather Service is forecasting a chance of mountain showers and thunderstorms on Thursday, June 18, in areas south of Highway 50. Forecasts show a 10% to 20% chance of precipitation in parts of the Sierra Nevada, including areas near South Lake Tahoe and Yosemite National Park. Widespread rain is not expected, but the storms could produce lightning, brief showers and gusty winds in small areas. By Friday, June 19, the weather service expects a gradual cool down with more seasonable temperatures to continue into the weekend. Read more at: www.sacbee.com
