All modeling pointing to a drastic one day flip from 70s to a frozen sleet,ice,snow event across CNE SNE. Not a big event but more notable for the quick sensible weather change. Depending on timing and intensity could be a commuter issue. Cold lower levels with a warm tongue at 775 825 level will cause sleet and mangled snow but some areas deep in the cold could pick up 2 to 3 of post 70 degree snow.
