Weather Forecast Is a Mixed Bag of Temperatures, But No Rain

Pasadena will experience a cooling trend Friday as strong onshore flow brings extensive low clouds and fog, according to the National Weather Service. A deep marine layer will struggle to clear throughout the day, with only partial afternoon clearing expected.

The marine layer is expected to slowly shrink into Saturday. A warming trend is forecast for the weekend.

Sunday is likely to be the warmest day for at least a week, if not longer, with mid-80s expected in Pasadena.

Looking ahead to next week, a cooling trend is expected to establish by Tuesday as an upper-level trough digs into the region.
