High pressure and dry air brought another delightful February day with temperatures 10 degrees above average. A weak storm is now in western Tennessee and will be moving to our south and out to sea by late Wednesday.  Even though the ground and roads are quite warm, enough cold air and moisture over us tomorrow that will be some light wet snow, mainly N&W of DC tomorrow afternoon.  The weak storm track a bit closer to southern Maryland means once again some chilly rain to the south of DC ending as a few hours of wet snow with no accumulation.  Even in the higher spots west and nort of DC only 1-2" on the ground.
