[STORMREPORTS] Mild WX Coming To An End In FL
As all know we have had mild weather so far in Florida in Fall 2004. But as I've warned for a good while now this pattern will come to an end, rather abruptly at that. The weather pattern will do a complete flip beginning on Saturday 12/11/04 to much colder and wetter and will last for the next 15-20 days.
The jet stream is currently transitioning into a Pacific North America (PNA) pattern. That means a big high pressure ridge in Alaska down through western Canada and the U.S. and a big trough in the eastern 2/3's of North America including Florida. We will also see a big ridge build in the Caspian Sea region of Europe.
This pattern will open the door to polar and arctic air masses to include the "over the pole" Siberian express deep into the SE U.S. as happened in December 1983 and 1989 and 2000. BUT at the same time we will see El Nino continue to slowly strengthen. This means undercutting low latitude winter storm systems and lot's of precipitation across the deep SW/S/SE U.S. Hopefully the arctic/polar jet streams will not phase with the El Nino stoked up subtropical jet and the coldest weather will stay north of the Florida peninsula.
How does that Bing Crosby song go?! "I'm dreaming of a white Christmas".
