Major flight delays are expected across the Plains today. Rain and thunderstorms will create delays much of the day from the western Gulf Coast through South Dakota, including Dallas and Oklahoma City. Houston, and New Orleans will see delays primarily late in the day.

Heavy snow will create delays all day across the central Rockies, including Denver. Travel across the region will become a nightmare with over a foot of snow expected over some areas. In the Northwest, mainly afternoon delays for rain will impact Portland and Seattle.
