An Ice Storm Warning has been posted for the Memphis metro area and I-40 corridor in west TN and east-central AR this morning, which is in effect from noon until 6am Wednesday. From the NWS: "SOUTHERLY WINDS ALOFT ARE FORECAST TO INCREASE AND OVERRIDE THE SHALLOW COLD AIR IN PLACE... A CLASSIC SETUP FOR AN ICE STORM." The Arctic front has arrived and temps are quickly falling - 19 degrees between 4:30am-6:00am at the Memphis airport. There could be some light freezing rain this afternoon in the city, but the big story could be overnight tonight, when up to 1/4" of ice falls on the city. This could be enough to down some power lines and cause some tree damage and is enough to create dangerous traveling conditions by Tuesday morning. Further updates are coming... stay tuned to commercial TV and radio, NOAA Weather Radio, and MemphisWeather.net for the latest on the developing winter weather scenario.
