For the very last times, old man winter will show his might, for this season. Wide spread frost is possible tonight, meaning that it might be a good idea to cover sensitive plants. Light freezes are possible on both Saturday and Sunday. After the weekend, North Florida will be done with freezing conditions, until the start up of next winter. Let the spring garden season begin!
So, why the sudden change? It all has to do with the location of our dominant high pressure system. Over the next couple of weeks, high pressure will start to bring up warm, tropical air from the south. This will in-turn raise our temperatures to average and eventually above average. Average temperatures for the last weeks of February range from 65-67 degrees. Jacksonville could see mid to upper 70's before the month is over.
At question is whether we can keep knocking down the 19 inch rainfall deficit of last year. So far, Jacksonville has made up 5 inches of that rainfall deficit, putting the deficit total at 14 inches. Whether or not we can keep up this pace remains to be seen, but it is likley that Febuary will end above normal on rainfall. March also looks it will come in about average, at 3.94 inches.
