SAN FRANCISCO (KRON) — The Bay Area is starting the weekend with wet weather and slick roads.
Showers began overnight Thursday into Friday morning in parts of the region, with slippery roads already seen well before sunrise. Around 8 a.m., Marin residents caught a double rainbow!

Showers reached San Francisco by 4 a.m. after falling over the North Bay.
The National Weather Service said there is a chance for thunder and lighting on Friday.
Rain showers will diminish from north to south with only lingering showers remaining over the Central Coast by nighttime, NWS says.
The wet weather Friday follows weeks of scattershot precipitation that has done little to ease drought.
Periods of rain, snow and much cooler temperatures are forecast through the weekend, and the National Weather Service says the state could be impacted by an atmospheric river next week that could deliver significant rain and snow.
The U.S. Drought Monitor says more than 95% of California has been experiencing drought conditions and the remainder is abnormally dry.

The road is always most slippery at the start of rainfall, so early morning drivers will have to be more careful than usual.
Drive 5-10 mph slower, keep a distance from other drivers and have your headlights on anytime the wipers are on, even during the day.
