NOTES-

Here on the south side of Lakeland February was significantly colder than normal and slightly drier than normal. The below normal temperature pattern followed December 2006 and January 2007, which together were the warmest since the El Nino winter of 1982-1983.

Thirteen days saw average daily temperature below normal, with eleven cold frontal passages. This occurred due to repeated periods with deep layered longwave troughing in the eastern U.S., as we saw a prolonged period of time where the jet stream teleconnection pattern (PNA) Pacific North America was positive and the (AO) Arctic Oscillation and (NAO) North Atlantic Oscillation were negative.

A significant cold wave occurred between the 15th and 19th, with one day with a minimum temperature below 32 deg. at 29 deg. and three days with a killing frost. Nearby areas that are 100-150 feet lower in elevation then my location saw three days with a minimum temperature below 32 deg., the lowest being 23 degrees and five days with a killing frost.

In the other extreme the month saw four days with a maximum temperature above 80 deg., with the highest being 83 deg. on the 28th. The month also saw two days with maximum dewpoint temperatures above 70 degrees, with the highest being 71 deg. on the 27th.

Tragically three EF3 tornadoes produced 21 fatalities across the central peninsula (Sumter, Lake and Volusia County's) on the 3rd, thanks to an El Nino stoked up subtropical jet stream winter storm. Speaking of El Nino it peaked at a moderate level in December 2006 and continues to weaken. There is growing evidence that a La Nina may form later in the Spring. This would produce a very hot month of May and into June, with a late start to the normal rainy season pattern and an increase the number of tropical cyclones that form in the tropical Atlantic Ocean basin similar to 2004.
