Widespread rainfall is expected late tonight or after midnight, and there’s a slight chance of thunderstorms Thursday morning accompanied by brief and heavy downpours and possibly small hail, forecasters said Wednesday.

Between a quarter-inch and three quarters of an inch is expected along the coast and in the valleys, and an inch is expected in the mountains, according to the National Weather Service.

In Long Beach, the National Weather Service said there is a 100 percent chance of rain early Thursday morning, and another chance for rain Saturday night into Sunday morning.

The snow level in the San Gabriel mountains will drop to 6,000 feet, the NWS said, adding winter driving conditions—meaning highly challenging—will prevail in the mountains.

Many rainfall records may be set tomorrow, according to the NWS, and the morning commute could be rough.

Also expected are stiff winds—around 15 miles per hour today and tonight in Los Angeles, and up to 40 mph Thursday in the San Gabriels.

The NWS forecast mostly cloudy skies today and a high of 70 in Long Beach.
