Pasadena residents should see low clouds and patchy fog rolling in by Friday morning and widespread showers this weekend, according to the National Weather Service, adding the active weather pattern could continue into much of next week. Temperatures may cool a few degrees due to the combination of the increasing cloud cover and onshore flow.
On Saturday, a more significant disturbance is expected to move into the region from the southwest, increasing rain chances throughout the day. The NWS says a six- to 12-hour period of light to moderate rainfall is possible Saturday, and snow levels in the mountains should remain above 8,000 feet.
A few degrees of warming is expected Sunday as the storm system moves east, but temperatures should still remain below normal.
Friday should see some patchy fog before 10 a.m., otherwise it should be partly sunny, with a high near 74 and a southwest wind around five mph.
Friday night should be mostly cloudy, with a low around 54 and a southwest wind around five mph becoming calm in the evening.
Showers are likely Saturday, with rain chances at 70 percent. The day should be cloudy, with a high near 65. A south southeast wind blows at around five mph.
Saturday night could see showers, with a low around 55. The chance of precipitation is 90 percent.
Showers are also likely Sunday, mainly before 10 a.m. The day should be partly sunny, with a high near 68. The chance of rain is 60 percent.
Sunday night should be mostly cloudy, with a low around 52.
Monday should be mostly sunny, with a high near 71.
Monday night should be partly cloudy, with a low around 51. The NWS says showers cannot be ruled out for Monday due to the moist southwesterly flow. Rain chances also increase Tuesday into Wednesday, as a cold front approaches from the west.
“Significant and widespread rain and mountain snow is possible with the cold front,” the NWS said in a forecast discussion. “This will likely be a much colder system with snow levels dropping with additional rain chances later in the week.”
