I went through Memphis on Wednesday and evening flights were delayed due to weather. MEM was closed to arrivals at 6 p.m. and did not open till around 6:45 p.m, due to thunderstorms. The flight I was on was due to land at 6:01 and we did not land till just near 7 p.m. I saw outbound delays going anywhere from 30 mins to 2 hours. Weather for Sunday night is looking much better than earlier in the week, only a 20% of rain.
