What to Know

  • Rain will be widespread Thursday before tapering off late Friday
  • Expect temperatures in the 50s for most of the LA area
  • The slow-moving cold storm finally moves out ahead of a dry and warmer weekend

Rain will be scattered early Thursday before becoming more widespread and steady as a lingering storm delivers one final punch. 

Expect cool temperatures and mountain snow during the last full day of wet weather from a storm that has drenched the region for four consecutive days.

"It's a very slow mover, and that's why this is Day 4 of that rain," said NBC4 forecaster Shanna Mendiola.

Most of the remaining rain is expected to fall Thursday, but the wet weather will continue well into early Friday.

Isolated flash flooding will be possible. A flash flood watch will be in effect in Orange County through Friday afternoon.

Heavy snow fell in the San Gabriel Mountains, and a winter storm warning remained in effect there until 5 a.m. Friday. Twelve to 24 inches of snow are expected above 6,500 feet and 6-12 inches at 5,500 feet. 

A mixture of rain and snow is possible as low as 4,500 feet.

Temperatures in Los Angeles will be in the 50s, well below average for this time of year.

Days of rain meant dramatic changes for the region's wet season totals. The water year is Oct. 1 to Sept. 30.

“Yesterday, we went above what we should see for this time of year,” said NBC4 forecaster Shanna Mendiola. “By the time we hit tomorrow, it may put us ahead of scheduled for the rain year.”

The storm will move out Friday evening, setting SoCal up for a dry and warmer weekend.
