Forecast 2013/01/15

500mb level winds. You can see the degeneration of the upper level trough through the animation. Note that it gets flatter and flatter with time.

Precipitation, with the rain/snow line in light blue. Note the orange polygon - this is where I expect a mix of wet snow and rainfall, leading to a slushy accumulation on grassy surfaces.
Snow accumulations for the Appalachian Mountains will be less than 1" - this system is moving too quickly and is weakening too rapidly to amount to much else. With a probable 8:1 snow ratio for the mountains, 7:1 for the foothills, and with the orange area, 6:1. Snow accumulations will be at maximum, 1-2"(southern Appalachian Mountains). I-85 northward will get a dusting to 1"

  1. The old timers are saying that mild winters come in pairs and this is 2/2 for us. Is this historically true? Do you think we will continue to have a mild winter again this year?
