(KTXL) — A strong late-season storm brought rounds of rain and heavy snow to Northern California and a tornado warning.

Just before 5 p.m., a tornado warning was issued by the National Weather Service Sacramento for Calaveras, Amador, San Joaquin and Stanislaus counties.

“Tornado Warning including Rancho Calaveras CA, Valley Springs CA, San Andreas CA until 5:15 PM PDT,” the NWS Sacramento tweeted.

The NWS Sacramento later extended the warning until 6 p.m. as the warning was about to expire.

The thunderstorms have the potential to bring heavy rain, lightning, and small hail.

The snow will be coming down in the Sierra for most of the day. The National Weather Service has issued a Winter Storm Warning for elevations above 5000 feet until 11 a.m. Friday. This is only the 6th April Winter Storm Warning issued by NWS Sacramento in the past 10 years. The snow will lighten up this evening and taper off tonight into tomorrow morning. Snow totals of 1 to 2 feet will extend the ski season.

The rain won’t bring California out of drought conditions, but it will lower pollen counts for a few days, and significantly lower energy available for wildfires by dampening fuels. Fire season will likely be on hold until mid-May for Northern California.
