Winter Weather Potential...
* Quick update after reviewing the 0z NAM (North American Mesoscale) model this evening...* This run suggests that the majority of precipitation here will fall in the form of rain, with the possibility of mixing with or changing over to snow before ending. Areas north of here (Tupelo, Columbus, Huntsville, Muscle Shoals - and on into the Carolinas and Appalachians) could see a very significant winter storm out of this.
* We'll mostly stick with the going forecast, with maybe a minor adjustment or too...Our latest thinking is....
MOSTLY SNOW north of a line from Grenada, Mississippi to Gadsden, Alabama. The potential exists here for 4-7" of snow. This includes places like Tupelo, Huntsville, and Muscle Shoals.
MOSTLY RAIN north of a line from Jackson, Mississippi to Alexander City, Alabama. This includes Meridian, Philadelphia, Macon, Demopolis, Livingston, York, and other communities north of roughly U.S. Highway 80. The rain could mix with or change over to snow Friday night. Snow accumulations seem unlikely at this point in time.
ALL RAIN south of a line from Jackson, Mississippi to Alexander City, Alabama. This includes places like Quitman, Bay Springs, Waynesboro, Grove Hill, and other communities roughly south of U.S. Highway 80. While we can't rule out a snowflake or two Saturday, that doesn't seem likely.
* I want to emphasize the uncertainty still remaining in this forecast. There are many factors that we'll have to closely monitor. Some of these factors could cause widespread and drastic changes to this forecast. We'll have to watch the progress of low-level cold air. If more cold air "seeps" in than our models indicate, this could lead to some ice. Another issue is the very deep, dynamic trough set to move through Saturday. These upper troughs can often serve up some major surprises...
* Another update to come tomorrow morning...
