Sierra Thunderstorms & Hot Mother Lode Temperatures
There will be thunderstorms in the Sierra Nevada on Friday afternoon and evening. They could return again on Sunday.
Cloud-to-ground lightning and gusty winds should be expected.
Hikers and campers should monitor the weather and seek shelter at once if threatening weather approaches. Lightning can strike several miles from the storm location.
Additionally, strong high pressure building across the region will result in very hot temperatures with record high temperatures likely in the Mother Lode on Friday and Saturday.
According to the National Weather Service, daytime high temperatures will be fifteen to twenty-five degrees above normal for this time of year. Daytime highs will range from 105 to 112 in the central valley and will be in the 80’s and 90’s in the upper Sierra Nevada.
Overnight low temperatures will range from the fifties in the high Sierra to the mid seventies in the central valley.
Complete outdoor activities in the morning. Care should be taken to ensure that sensitive groups including the elderly and small children, limit their exposure to the heat. Pets should be kept inside cool areas and special care should be given to keep livestock cool and hydrated. Pets and livestock are susceptible to death at these extreme temperatures.
