Expect a warm, mostly sunny day across Delmarva today with temperatures reaching the upper 70s to low 80s inland. A cold front will arrive late Sunday, bringing cooler temperatures, gusty winds, and dry conditions through midweek. Keep an eye on the sky as well: Comet C/2023 A3 Tsuchinshan-ATLAS will be visible low on the western horizon after sunset, offering a rare opportunity for stargazers.
