Severe weather will shift to the western Gulf Coast on Monday, becoming replaced by a chilly rain and wind in the southern Plains.
Monday's severe weather will follow the violent thunderstorms that will target Dallas and Oklahoma City to end the weekend.
While these cities will turn cooler to start the new week, the severe weather threat zone will center on Houston and College Station, Texas and Lake Charles, Baton Rouge and New Orleans, Louisiana.
"Monday will bring a one-two punch of strong storms to southeastern Texas and Louisiana," stated AccuWeather.com Meteorologist Becky Elliott.
"A squall line looks to move through [southeastern Texas and western Louisiana] in the morning hours and could produce damaging winds and torrential downpours," she continued.
In addition to the potential for some tree damage and power outages, those in Houston will be faced with a slower commute with possible delays to both air and ground travel.
Downpours accompanying the squall line would dramatically reduce visibility and cause water to pond on roadways, heightening the risk of vehicles hydroplaning at highway speeds.
In the wake of the squall line, Elliott added "Residents of southeastern Texas and Louisiana should not let their guard down though as storms are likely to develop late in the afternoon."
"The environment holds the right ingredients for these storms to produce strong winds, large hail and an isolated tornado or two."
Unlike the morning hours, New Orleans and the rest of eastern New Orleans will not escape the severe weather danger in the afternoon.
North of the severe weather, a quiet day with sunshine is not in store for Dallas, Oklahoma City and the rest of the southern Plains.
Gusty winds will usher in noticeably cooler air as rain persists. The steadiest rain will fall from Oklahoma to the northern Texas Panhandle and southeastern Colorado.
There is concern that the rain will be heavy enough to cause flooding in low-lying and poor drainage areas, especially around Oklahoma City.
Temperatures will be held 20 to 25 degrees below Sunday's highs, but the combination of the wind and rain will create even lower AccuWeather.com RealFeel® temperatures.
The air will be so cold that snow will fall in the mountains of Colorado and New Mexico, even into the lower elevations near the eastern border of these two states.
The snow threatens to create slow travel on the stretch of I-25 from Raton, New Mexico, to Trinidad, Colorado, Sunday night through Monday.
An end to the snow will come by later Monday with the southern Plains turning drier, sunnier and warmer Tuesday through Wednesday. At the same time, soaking rain and thunderstorms will spread across the South.
