Mount Magazine Ice Storm
While most of our area was above freezing during last nights rain at least one place managed to see some fairly significent ice. Mount Magazine - the highest point in Arkansas had some spots with as much as 1 inch of ice accumulation. The ice began at about 2000 feet but only existed on the eastern half of the mountain. The visitor center had half a inch of ice accumulation but just 1/4 of a mile west towards the new lodge there was no ice at all. I think this had something to do with the easterly winds we experienced during the overnight advecting lower slightly drier air onto the eastern slopes. This slightly drier air allowed the temperatures to dip just below freezing through the effects of evaporation. The western slopes were protected from the wind and the slightly drier air and were thus able to remain just above freezing. The difference was probably only a few tenths of a degree but it was the difference between no ice and 1 inch of significent ice accumulation. Here are a couple more pictures showing 1 inch of ice accumulation and the ice line at around 2000 feet. More pictures can be seen at HERE.
