Region 1
An area of low pressure east of the Rockies is pulling warm moist air northward from the Gulf of Mexico through the Ozarks and mid-Mississippi Valley. This system will be moving eastward today and tonight, bringing a dryline through Oklahoma and developing a warm front to the northeast. Also, a shortwave trough will be moving over the region this afternoon and evening. Strong to severe thunderstorms may develop along the dryline this afternoon and evening in far eastern Oklahoma and Arkansas, and then northward into Missouri, Illinois, Indiana, and parts of Kentucky. Large hail and damaging winds will be the primary hazards, but an isolated tornado cannot be ruled out. Later in the evening as storms develop northward, the threat will likely transition to mainly high winds. Severe weather may continue overnight as the system moves eastward, extending from the Southern States northward to the Great Lakes.

Strong to Severe Thunderstorms Possible for the Missouri and Ohio Valleys on Tuesday
The area of low pressure responsible for the severe weather potential on Monday will allow for a risk for severe thunderstorms over the Mississippi and Ohio Valleys on Tuesday. Scattered showers and thunderstorms may be ongoing during the morning hours, with a risk for severe winds. Activity will continue into the afternoon and evening hours as a cold front presses eastward throughout the day. Daytime heating and abundant moisture will promote modest instability with a greater threat of severe thunderstorms later in the day. Large hail, damaging winds, and tornadoes will all be possible with these storms.
