The light showers that sprayed Southern California on Thursday night -- causing a burst of glee on social media -- likely won't return until Sunday, forecasters say.

But even if the slight chance of rain pulls through, it won't be much, said meteorologist Curt Kaplan with the National Weather Service in Oxnard.

"It looks like a fairly light event again, less than a quarter-inch," he said.

While the rain may be hardly noticeable, the drop in temperatures will be. After a period of above-normal temperatures that at times reached into the low 80s, the weather system is ushering in a significant cool-down.

For much of the next week, daytime temperatures aren't expected to get past the low 60s in most areas, according to the weather service. And L.A. County's top health officer issued a cold weather alert for the Mount Wilson and Antelope Valley areas through Tuesday as wind chill temperatures are expected below 32 degrees.

But it's the chance of a rare rain shower that is keeping Angelenos in a state of hope after nearly an entire month without any measurable precipitation during what is typically one of the Southland's wettest periods.

Residents and commuters took to Twitter on Thursday night as the first wave of possible rainfall swept across the region.
