Actually after I realized you were talking about SoCal water I deleted my post. Yeah, that's chilly haha, anywhere north of Encinitas or thereabouts at any rate. San Diego area water isn't terrible.
Somebody in Hatfield, Hadley or S Hadley might have seen a strong localized wind gust. Some evidence on radar of a collapsing cell. On the whole, NBD obviously.
The drought in 65-66 was no joke in these parts. Quabbin set the low bar for water levels way beyond anything we've seen. A couple years ago it got to the lowest level since 66, but wasn't close to that.
