Pasadena can expect some sunny and clear changes in weather conditions over the weekend, according to the National Weather Service.
Saturday, a high-pressure system will bring warmer temperatures and clearer skies as morning clouds and fog dissipate. But on Sunday, a weak upper-level low-pressure system will cause morning fog and early morning cooling before the sun returns.
Both days will end up being 77 degrees.
Pasadena’s weather will take a more significant turn on Monday through Wednesday when a stronger low-pressure system arrives, resulting in much cooler temperatures and a slight chance of showers and thunderstorms.
The National Weather Service predicted a cooler air mass is expected to persist throughout the week, accompanied by extensive low clouds.
June Gloom, characterized by lingering clouds, is expected all next week.
