Cold, Wet, Winter Weather Bearing Down On Pasadena

On the heels of a week that brought the Southland dry conditions and Santa Ana winds, cold and wet weather will be moving into the Pasadena region starting Friday, bringing daily off and on rain daily through next week.

National Weather Service forecasters said an upper-level low-pressure system will make its way into the Southland Friday, giving the region “very cool and unsettled weather” for days.

NEWS said showers are likely today, mainly after 4 p.m. under mostly cloudy skies with a high of just 57.

“At this time, (forecasters) do not anticipate this system to have a lot of moisture to work with,” according to the NWS. “So, rainfall totals will not be too impressive, with most areas receiving under one-quarter inch of rainfall, with local amounts up to around one-half inch across the San Gabriel Mountains.”

But the cold system will give the mountains a taste of winter. The snow level is expected to drop to about 5,000 feet Friday, then down to 4,000 feet Friday night and Saturday.

The unsettled nature of the storm system could also mean potential thunderstorms on Saturday.

Forecasters said the weather should be calm Saturday night into Sunday, but by Sunday afternoon, another storm system will make its way into the area.

“As for temperatures, expect a very cool weekend for all areas,” forecasters said. “Afternoon temperatures will struggle in the 50s to lower 60s with cool overnight low temperatures.”
