Afternoon and evening thunderstorms are possible today in northern California and east of the Cascades. Cloud to ground lighting, gusty winds, and small hail may be present with these storms.
An upper trough around a low pressure system over the Gulf of Alaska will support seasonable temperatures through the week. Instability around this system and daytime heating may bring isolated rain showers or thunderstorms in the afternoon and evening of most days over northern California counties and areas east of the Cascades. Awareness of thunderstorm safety is encouraged.
Thunderstorms produce deadly lightning capable of striking up to 10 miles away from the storm — so, even if you don't see rain you could be in harm’s way. Remember this simple message: When Thunder Roars, Go Indoors!
