Thunderstorms with severe wind gusts and hail will be possible today across parts of the central Plains, and from the Missouri Valley into the upper Mississippi Valley. Heavy rain associated with the thunderstorms may also produce flash/urban flooding. Critical fire weather conditions expected in the Great Basin and interior Northwest. Dangerous heat continues across the Southwest and Southeast. Read More >

We have extended the Lake Wind Advisory for the San Luis Reservoir and along Highway 152 through 11 PM Thursday (Jul 9). We have also issued a Lake Wind Advisory for Lake Isabella and the Kern River Valley from 5 PM this afternoon until 11 PM Thursday. Sustained winds of 15 to 20 mph and gusts up to 35 mph are expected at San Luis Reservoir. Sustained winds of 15 to 25 mph and gusts up to 40 mph are expected at Lake Isabella. Gusts this high are capable of producing whitecap waves dangerous to small watercraft and are dangerous to drivers, particularly those in high-profile vehicles. Exercise caution if recreating at San Luis Reservoir and Lake Isabella or driving in the area.
CPC 6-10 day temperature outlook has the Central Valley mostly in the 60-70% probability for above average temperatures from July 12th-16th. The 16th looks to be the hottest day on this outlook. Remember to stay cool, avoid the outdoors during the hottest parts of the day, and help the more vulnerable population (infants, 65+ years of age, unhoused) to stay cool.
Starting next week, models indicate an ideal pattern will push monsoon moisture into California. Current rainfall estimates are highly uncertain. There is, however, medium forecast confidence for more widespread mountain thunderstorms, some of which may cause dry lightning strikes. Check our website (weather.gov/hnx) for updates.
