Here It Comes.
New models this evening and now the trend appears that the Low looks to be heading a bit further south with the main system and a bit colder as well. This means that during the past day or so the system had been moving a bit further north with the low moving out of Louisiana along I-20 in Alabama and then east towards Georgia. That meant it would most likely have remained mainly rain from Mississippi into Northern Alabama and Georgia during the heaviest precipitation. Now during this same time, the ECMWF (Euro) model had been a bit of an odd man out (so to speak)with the track hugging the northern Gulf coast and indicating the potential for more frozen precipitation further south to near the Tennessee River. The freeze line now looks to dip below the Tennessee/Alabama state line and the NAM shows the Precipitation moving into NW Alabama around noon on Friday and then moving East throughout the afternoon likely as freezing rain. The freezing line should make it near the Tennessee River by 3:00pm and then start moving back to the North.Some models are showing a heavy band of snow from near Highway 72 up towards Nashville. This is not in stone YET all it takes is a jog of the LOW of just a few miles for it all to change again, but it is getting more and more consistent. Stay tuned to local news for the Latest.
