Temperatures last night dropped to freezing conditions, with numbers hitting the 20s in the North Bay. San Francisco will reach around 56 today, with the highest temperature going to Mountain View with 62 degrees. Rain, which would bring some relief to this dry-skin weather, might fall come Thursday. Anyway, it's chilly. We could barely sleep last night what with the prickly weather jabbing us throughout the evening. Time to crank up your space heaters, folks. Brr.
