Meanwhile, a major storm will brew across the southern tier of the country. Heavy rain and locally strong thunderstorms will stretch from eastern Texas through the lower Mississippi and Tennessee valleys.
New or worsening flooding problems can arise in this corridor. Snow will threaten slick travel on the northwestern flank of the storm across the southern Rockies and central Plains.
An icy mix can occur between the snow and rain zones in the South Central states. A new storm is forecast to sweep into the Pacific Northwest with rain for coastal areas and snow for the interior.
