Fog Time-Lapse Video Shows Exactly Why Bay Area Is Less Sweltering Than Monday

SAN FRANCISCO (CBS SF) - Don't be surprised if it feels a little more muggy during your outdoor strolling Tuesday. Moisture has moved in and cooled the Bay Area significantly.

"We have a marine layer moving in and wind gusts up to 30 miles an hour," said KPIX 5 Weather Anchor Roberta Gonzales, who says that moisture will combine with what's left of Tropical Storm Blanca moving up the coast from Mexico. "Look for these increasing clouds and temperatures in the 60's to low 90's, that's a full 15 degrees cooler in some locations."

Monday was the hottest day in the Bay Area since last June 8th & 9th, almost exactly one year ago. But by the morning commute Tuesday, people in San Francisco were reminded why you always need to carry a jacket. Here's a look at the fog moving back into the city.

"We could even see some drizzle lining the coasts and into the bay," said Gonzales.

Tonight will be mostly cloudy with a slight chance of thunderstorms and a chance of showers after midnight. Lows will be in the mid 50s and Southwest winds will reach 5 to 10 miles per hour. The computer models are leaning towards the highest probability of thunderstorms in Monterey and San Benito Counties. However, there is a chance thunderstorms containing lightning pop in the Bay Area.

Wednesday will be mostly cloudy with highs in the 50s to upper 60s. West winds will reach 5 to 10 miles per hour.
