We're reaching the tail end of our recent clear sky/cold air trend. The progressive, active pattern of storms movement across the southern tier of the country is still evident ... and as a result, we'll experience increasing cloudiness for most of Friday as moisture returns from the Gulf in advance of the next low-pressure storm system that will enter the Deep South by late Friday. The best chances for showers and a few thunderstorms will be late Friday night through the first half of Saturday, with only a limited opportunity for significantly-strong storms. Another surge of colder northern air will follow for the remainder of the weekend, then, to close out the year 2012, more cloud cover and showers chances will come back.
Tonight, lows will fall to the 30-degree mark east, slightly warmer west with more clouds. A freeze warning will be in effect for many eastern counties in north Florida overnight through 8:00 or 9:00 a.m. Highs regionwide will recover to the low to mid 60s.
