AccuWeather Forecast: Cloudy and cooler with chance of light showers

SAN FRANCISCO (KGO) -- The hot weather that briefly hit the Bay Area Tuesday is gone, but has been replaced with a humid day on Wednesday with the possibility of light showers.

Monsoonal moisture arriving from the south will bring shower chances throughout the day and an increase in clouds.

The biggest impact may be wet roads.

While it will feel uncomfortably humid, high temperatures will be 20 degrees cooler compared to Tuesday.

Any shower would be light and just a few hundredths of an inch of rain. Shower chances will diminish near midnight with drier weather returning Thursday.

This comes just a day after some cities inland saw triple-digit heat, and San Francisco saw nearly 90-degree weather.
