A pretty vigorous low pressure system will eject across the Southwestern United States and move into the Lower Mississippi Valley this weekend, then moving into the Tennessee and Ohio River Valley Region by early next week. A weaker system with much colder air behind it, will phase with this system to potentially bring the first winter storm across the Ohio River Valley Region.
Many of the GFS (American) and European Ensembles continue to show a large swath of snow extending from Eastern Illinois to Indiana, Ohio, Kentucky, East Tennessee and across the mountain chain from North Carolina, Virginia, West Virginia, Maryland, and, Pennsylvania.
Monday: The latest European model shows low pressure moving across Eastern Tennessee into Southwestern Virginia. Much colder air on the backside of this system will produce moderate to potentially accumulating snow across Indiana, Western Ohio, and portions of Western Kentucky, and Western and Central Tennessee. Temperatures EAST of the system will climb into the 40’s and 50’s. TRENDS HAVE NOT been for this system to be further east AT THIS TIME, so we expect RAIN EAST OF THE MOUNTAINS.
