Overview

• The Bay Area experienced an unprecedented heat wave in early October, with temperatures reaching record highs in multiple cities.
• Meteorologists underestimated the duration and intensity of the heat wave due to a persistent high-pressure ridge that stalled over the region.
• Temperatures began to cool on Tuesday, with a more significant drop expected by the weekend as a low-pressure system approaches from the Gulf of Alaska.
• A slight chance of rain is forecast for the Bay Area this weekend, with the North Bay having the highest likelihood of receiving light showers.
• Despite the cooldown, temperatures are expected to remain above average for the next week, with more typical fall weather anticipated by mid-October.
