Pasadena will see clear skies and mild temperatures Tuesday before strong Santa Ana winds arrive later this week, according to the National Weather Service.
Forecasters said Tuesday morning that highs will reach near 78 degrees under sunny skies, with light southwest winds around 5 mph. Overnight lows will dip to about 53 degrees under clear skies.
Winds are expected to increase Wednesday afternoon through Thursday, with gusts of 35 to 50 mph possible in mountain passes and freeway corridors. Localized gusts could reach 60 mph in exposed areas. Pasadena neighborhoods near canyons may feel stronger breezes as the system moves through.
Temperatures will cool slightly midweek, with highs around 75 degrees Wednesday and 73 degrees Thursday. By Friday, highs will rebound to 73 degrees, climbing into the upper 70s over the weekend. Saturday and Sunday are forecast to reach 78 degrees, with sunny skies and overnight lows in the low 50s.
The weather service said the strongest winds will occur Friday and Saturday, when advisory-level conditions may extend into valleys and coastal areas. Impacts could include downed tree limbs, power outages and hazardous driving conditions on the 210 Freeway. Pasadena residents are advised to secure outdoor items and prepare for possible disruptions.
While Pasadena is expected to remain dry, light showers are possible Wednesday night into Thursday morning in the Grapevine area. Early next week, forecasters noted a low-confidence chance of very light rain in eastern Los Angeles County.
By Monday, highs near 79 degrees are expected in Pasadena, followed by a slight cool-down and a chance of light rain before another warming trend later in the week.
