It all starts Monday, as a stripe of snow, sleet and freezing rain develops by morning from parts of Kansas, Oklahoma and possibly extreme north Texas, then spreads eastward into the Mid-South region.
Several inches of snow and sleet may accumulate by early Monday evening in parts of Oklahoma, Arkansas, and possibly parts of west Tennessee and northern Mississippi. Travel may become hazardous in these areas by midday Monday.
Monday night into Tuesday, cold air near the surface will continue to build into the Tennessee Valley and down the piedmont of southern Appalachians.
This means precipitation may change from rain to freezing rain from parts of northern Louisiana into northern Mississippi, northern Alabama, and north Georgia Monday night into Tuesday.
At this early juncture, it remains unclear whether surface temperatures will remain below freezing for a sufficient time period Tuesday to lead to significant travel disruption.
At the same time, snow will shift out of Arkansas and Oklahoma into Tennessee, southern Kentucky, North Carolina and southern Virginia Monday night into Tuesday. Some sleet or freezing rain may fan out over parts of southern North Carolina and northern South Carolina.
Wednesday, the wintry mess of snow, sleet and freezing rain may linger in the southern Appalachians and adjacent piedmont of north Georgia, the western Carolinas while spreading farther north into Virginia and the Delmarva Peninsula.
While it's still too early for precise snowfall totals in these areas Tuesday into Wednesday, even light snow and/or sleet/ice accumulations may make travel difficult.
Despite some hype from other sources over a week out, there was no Northeast "Megastorm" this Sunday or Monday.
With that said, there is potential for low pressure to sweep up the Northeast seaboard on the back end of the work week.
