Discussion

Tropical Storm “Zeta” is headed for a landfall later tomorrow in the central Gulf coastal region of southeastern Louisiana likely as a category 1 hurricane. This system will then make a turn to the northeast after coming inland and head over the Southeast US and reach the Mid-Atlantic region by late Thursday. The tropical moisture from the remnants of “Zeta” will combine with vigorous upper-level support to result in a significant rain event for the Tennessee Valley, Mid-Atlantic region and southern New England from Thursday into early Friday. Later Friday, cold air will drop southeastward from the Great Lakes and get wrapped up into the storm system that will then be centered off the Mid-Atlantic coastline. This could actually result in a changeover to snow across portions of the Northeast US with accumulations on the table.
