We don't get dozens of days per year like this one here in SF. I suggest you get out, like now, and take advantage of it.
The weather this weekend is calling for some cloudy skies and much more SF-typical temperatures in the 50s and 60s.
As Hoodline tells us, heat like today's is expected to return on Tuesday and Wednesday of next week, though, so you better get this leaving-work-early routine down. You only live once, you've heard that right?
Expect tomorrow to be kind of chilly!
You've only got one shot at this this week.
