A storm system which will eject out into the Plains Monday night will spark a severe weather outbreak Tuesday across the lower Mississippi Valley.
This will be the same storm that drops heavy snows on the northern Plains Monday night and Tuesday.
On the warmer side of this storm, strong winds coming out of the Gulf of Mexico will transport deep moisture into parts of the southern Plains and lower Mississippi River Valley by Monday night.
This moisture and these strong winds aloft will interact with the approaching storm sparking showers and thunderstorms from eastern Oklahoma through southern Missouri and western Kentucky southward to the Gulf Coast beginning late Monday night.
Storms initially could develop during the overnight hours early Tuesday morning from eastern Kansas through eastern Oklahoma and northeastern Texas, including the cities of Topeka, Tulsa and Texarkana.
Nocturnal storms are the most dangerous type as they can produce damaging winds and drop tornadoes with little warning. With most people asleep during these times, it's harder to get across warning information to residents in the paths of these storms.
The severe weather threat will rapidly increase farther to the east on Tuesday as surface heating combines with the approaching storm and all the moisture available.
Cities in line for the greatest threat of severe weather Tuesday afternoon and Tuesday night include Shreveport, La., Little Rock, Ark., Memphis, Tenn., and Cape Girardeau, Mo.
Damaging wind gusts to 70 mph, a few tornadoes, and hail to the size of baseballs will all be possible with the strongest thunderstorms.
A nocturnal severe weather threat Tuesday night will likely continue into Kentucky, Tennessee and northern parts of Alabama and Mississippi with damaging winds becoming the main threats.
Keep checking back with AccuWeather.com over the next few days as we begin to detail the severe weather potential Monday night through Tuesday night.
