Altadena Weather: Sunny. Windy. Warm. Repeat.

An upper high pressure ridge is expected to amplify and build into California Sunday night and will bring sunny and warm weather over Altadena Monday, but this comes with strong and gusty winds near the foothills that could create driving hazards through next Saturday.

Monday’s highs will be near 89 degrees with northeast winds at five to 15 miles per hours, becoming east southeast in the afternoon. A Hazardous Weather Outlook from the National Weather Service says winds could gust as high as 20 mph Monday afternoon, even up to 60 to 65 mph in the windier locations in the mountains and foothills.

Monday’s lows will be around 57.

Tuesday will be sunny and could be the warmest day of the week with a high near 90 in the valleys and interior areas of Los Angeles county, as the upper high gets to its strongest across the region. Calmer winds from the south and southwest prevail and lows will be around 59.

Wednesday expects some significant cooling as the upper ridge flattens and moves east. Maximum temperatures will be down more than 10 degrees and clouds will increase, with highs around 79 and lows around 54.

A slight chance of rain is predicted Wednesday night, which is expected to be be mostly cloudy.
