Yes, it's time to break out that thermal underwear. It's going to be freezing tonight, the kind of cold that'll cut right through your San Francisco hoodies.
The National Weather Service has issued a freeze warning for the San Francisco Bay Area starting tonight at 9 p.m. through 9 a.m. on Friday. Temperatures will drop to 30 degrees along the coast and hit the 20s and 30s inland over the next few days.
What we're trying to say is: cover your outdoor pipes and plants, then get inside and cover yourself with a blanket -- or four.
In San Francisco, it will be both cold and wet by Friday. According to the National Weather Service, rain is likely to fall after 4 p.m. and temperatures will drop to 43 degrees by Friday night.
