Thought it was supposed to stay cloudy all day. If I'd known the afternoon was going to be sunny I'd have brought my hat, and a book to read on my walk home. Reading on my phone doesn't work on sunny days because the screen just gets washed out, unless I set the text size to something ridiculous like six words per page.
It seems like, if it isn't actually raining, drizzling or about to rain, it's damn hard to get an overcast afternoon in the DC area. IIRC these were a lot more common in the 70s and 80s.
