I've been in SoFL since 1965, including the snow year of 1977, and I understand exactly what you mean. Right now we are at 76F with a low of 70F at sunrise tomorrow and low 80sF by afternoon. Next week we may have early morning lows in the mid-50sF with highs in 70s to 80s depending.
We had a cool late December and all of January. Morning lows on 50sF with daytime highs in 70sF with an occasional day or so with strong north winds about 10 degrees cooler, cloudless skies and no rain. Since the start of February the wind has shifted to the SouthEast. Warmer summer like weather with almost daily rain. This is at least a month or 6 weeks too early.
What you are getting we are going to get the tail end of sometime next week, thus the lower temps then.
NJL (.. Fear not, dear northeners, June 1 is coming and the "mean season" begins with our constant monitoring of the Weather Channel and the National Hurricane Center...
