SACRAMENTO, Calif. (KTXL) — Scattered breaks of dry weather between rounds of rain are expected Wednesday.

More downpours are likely with a slight chance of thunderstorms, which could produce heavy rain, lightning, gusty winds and small hail.

Tuesday, thunder was heard near Sacramento Executive Airport around 2:30 p.m., along with hail in midtown Sacramento. Small hail kept falling throughout the region Wednesday.

More thunder was reported just to the west of Stockton by the National Weather Service about an hour later. The agency urged people to stay inside.

Snow in the Sierra continues to come down Wednesday. Like the rain, there will be dry breaks at times.

The Winter Storm Warning remains in effect until 7 p.m. Wednesday for elevations above 3,000 feet.

By the afternoon, the California Highway Patrol said a jackknifed big rig and multiple spinouts were causing traffic backups on Interstate 80 in the Sierra.

Chain controls moved down to lower elevations for part of the day as snow fell.

The storm will fade in the afternoon and exit the area Wednesday night, setting us up for a crisp and cool Thursday. Sunshine and highs in the mid-to-upper 60s return on Friday.
