Pasadena will be partly sunny Sunday, but this will probably be the last dry day before a week of rain, as the National Weather Service sees a series of storms lining up across the Pacific Ocean that could threaten Southern California through next week.
“A series of frontal systems originating over the Pacific Ocean will bring widespread rain, mountain snow and gusty southwest winds at times through the next seven days,” the NWS says in its latest forecast for Southwestern California. “Daytime temperatures during this time are expected to remain generally below normal due to the increase in clouds and precipitation.”
The first storm is expected to bring a threat of rain to the central coast by Sunday afternoon, and Pasadena should see a 10 percent chance of rain after 4 p.m., with winds from the south and southeast blowing at five to 10 miles per hour.
Tonight, the chance of rain goes up to 60 percent especially after 10 p.m.
Highs today will be around 63 degrees, lows around 50.
Starting Monday, the chance of rain ranges from 70 to 80 percent over Pasadena and the rest of Southern California, and builds up to 90 percent by Tuesday as a stronger storm system hits areas northwest of Los Angeles County.
“The second storm on Tuesday is forecasted to be stronger with more southerly flow that will help to enhance rainfall totals, especially across south facing mountains and foothills,” says a Special Weather Statement from the NWS. “Valley areas can generally expect between one and two inches of rain with this system.”
The NWS says it is considering issuing a winter storm watch over the area as the storm systems draws closer.
The storm systems will also bring colder temperatures over the next few days, with Wednesday bringing in a high of 51 and low of 42, and Thursday and Friday with highs of 54.
The weather lightens up a bit starting Saturday, when the chance of rain goes down to 27 percent over Pasadena and warmer temperatures prevail.
