If I read the weather forecast correctly there is a good chance for rain. Make sure you test night / rain conditions with a bigger grid, my hardware wasn't all too happy with that, even with low gfx settings.
Have gone from 100% chance of rain, down to 85% now. That's something.
Also remember that it's using local times, so Daytona Beach is UTC-5, so compared to local times, it's UK -5, Central Europe -6, Eastern Europe -7. So when you look at weather, remember to look at the right time
