That slight warm patch of weather that typically hits San Francisco around this time of year might have come and gone already. Today at around noon-ish, rain will pour down on the city, wiping away weeks of dirt, grime, and chalky film. But, according to The Chronicle, today's drenching won't be nearly as big as tomorrow's storm "forecast to blow through Northern California starting late Tuesday or early Wednesday."
Rainfall in San Francisco and Oakland could go well over one-inch. (Weather, however, is expected to clear for the Blue Angels, who are scheduled to practice over Bay Area skies from 1 to 5 p.m. on Thursday and 12:30 - 4 p.m. on Friday.)
Time to break out your umbrellas, folks. Summer is over.
