New Orleans Weather many locations will be waking up to lower 30s again! It was a cold start, no doubt about that and it'll remain chilly through the afternoon. With the brisk winds that'll add more of a bite to the air. Daytime high are expected to only climb to the low to mid 60s. Tonight is another cold one, but with calmer winds. Frost will be possible north of the lake, so it's a good idea to protect tender plants north of the lake. Southshore will stay in the mid to upper 40s.
