Question about timing of return flight out of Houston Hobby

[cruisemein]

My wife and I are cruising out of Galveston, departing 2/25 and returning 3/4....been reading about all the fog. We currently have a 2:00 departure out of Hobby. The question is should we move it to the next flight which is 5:00. Back in Sept we were at the airport by 11:00, but that was Sept, no weather issues or delays. Just asking for a little input.
