Florida Cold

So I am told that Florida is having the coldest weather this week that they have had in a decade.  Not sure if that is true but it is cold, like 28 in the am and warming to high 40s last two days.  It has given the fish lockjaw for sure.  I have caught 2 fish in as many days way up the river.  Not too promising but the weather is supposed to change and I hope it effects the fish quickly.  I need all the help I can get right now.
