Rain and storm chances stay elevated on Friday, especially along the East Coast. While some drier air may try to push in from the Atlantic this weekend, typical afternoon sea breeze storms remain likely both Saturday and Sunday.

Models suggest that moisture may linger into early next week, though a brief drying trend is possible if high pressure builds. Temperatures will hold in the upper 80s to low 90s.
