The National Weather Service has issued a Winter Storm Watch for several counties West of the Mississippi River.  Precipitation is beginning to build in Oklahoma and Western Arkansas.  Most of it so far has been in the form of very light rain.  There is snow in Missouri and Eastern Kansas as we speak.  Temperatures are right at the freezing mark in Memphis.  Rain and Snow is likely Monday with the best chances for accumulating snow North of Memphis.
