Sacramento, CA – Northern California residents could face changing weather conditions beginning Tuesday, October 20, as a new round of rain, isolated thunderstorms and cooler temperatures moves across the region through Thursday.
According to the National Weather Service NWS in Sacramento, widespread precipitation chances are expected Tuesday through Thursday, October 22, with isolated thunderstorms most likely Wednesday between 10 a.m. and 10 p.m.
The unsettled weather could affect Sacramento, Stockton, Modesto, Chico, Redding, Yuba City and surrounding communities, bringing periods of wet pavement and potentially longer commutes.
Thunderstorms Could Bring Lightning and Small Hail
Forecasters say Wednesday's isolated thunderstorms could produce lightning, small hail, brief heavy rainfall and gusty winds.
While widespread severe weather is not indicated, sudden downpours could reduce visibility and create slick conditions for motorists, particularly during periods of heavier rainfall.
Rainfall totals will vary considerably across Northern California.
Sacramento and nearby valley communities could receive approximately 0.10 to 0.25 inches of rain, while portions of the northern Sierra Nevada and surrounding foothills could see 0.50 to 1 inch.
Other locations, including Stockton and Modesto, are forecast to receive lighter precipitation.
Mountain Snow and Travel Impacts
Higher elevations could also experience snowfall as temperatures cool.
The NWS forecasts snow levels initially around 4,500 to 5,500 feet, rising above 6,000 feet Tuesday night before falling again Wednesday night.
Light snow is possible above 8,000 feet, although significant accumulation is not currently expected across most populated areas.
The overall weather impact is classified as minor, with slick roads and longer than normal travel times among the primary concerns.
Residents should monitor changing forecasts, allow additional travel time and remain alert for lightning during thunderstorms.
