Hot and humid conditions persist today. A cold front crosses later today and tonight, bringing showers and storms this afternoon and evening. A few storms could be strong to severe with damaging winds the primary hazard, and high rainfall rates in any slow-moving storms could pose a localized flash flood risk. Behind the front, some relief to the humidity is likely over the weekend. Another cold front crosses late Sunday bringing a cooler airmass into next week.
