Frosty Nights, Mild Weekend

Friday starts with a little frost on the windshield and ends sunny, with a high near 57. The story of this weekend is what happens after dark: Friday night and Saturday night both fall to 30, with widespread frost settling in after 11 p.m. — exactly the kind of night that finishes off tender plants and splits hoses left full of water.

Saturday brings mostly sunny skies and a high near 59, though temperatures ease back down through the afternoon. Sunday is the pick of the weekend — sunny, high near 63, the morning frost gone before 9 a.m. Monday turns milder still, near 66 under sunny skies, with patchy frost before 9 a.m.

A practical note for gardeners: this is the second straight night at or near freezing, and Saturday night repeats the 30° low. Cover what you want to keep, drain hoses and watering cans, and if the potted herbs haven't come in yet, tonight is their deadline. By Monday's warmth, the danger eases — at least until the next cold push.
