The water temps in Galveston Bay got down into the upper 30s. It's already up to 43 at that station. It probably got colder than that in some of the still backwater areas. It was 45 here on Lake Pontchartrain. The only effect it had was stacking fish up in the deeper spots and making them easier to catch.
