Wedding forecast for March 28th 2020

I'm having my wedding March 28th 2020 and i was wanting to know the forecast for that whole day it's an outside country themed wedding everything is outdoors

Galveston Tx beach weather Feb 17-21

It's worth a shot - I am planning a beach photoshoot in Galveston,Tx. The photographer will only be in town from Feb 17-21 2020. I am looking at monthly forecasts nonstop and it went from sunny with chances of rain, to all rain, to one day being sunny, back to a rain out all week. Houston has been pretty wet this February and I am curious if I should not chance it? This photographer is quite pricey and I will not be able to get a refund. What are your thoughts? I also think Galveston Mardi Gras is around this time too. Thanks!
