1:30 PM | *Severe weather threat on Saturday in portions of the Mississippi and Ohio Valleys to include potential tornadoes*
Mississippi Valley, Ohio Valley: A classic pattern for severe weather in March is setting up for Saturday in the Mississippi Valley and potentially the Ohio Valley with cold, Arctic air to the north and west and warm, humid air to the south and east. In this “battle zone” region, severe thunderstorms are likely to break out on Saturday across portions of Tennessee, Mississippi and Alabama and this threat includes large hail and perhaps a few tornadoes. There is also a chance this severe weather threat on Saturday extends as far north as the Ohio Valley region including southern Illinois, southern Indiana and western Kentucky. Strong low pressure will head northeast on Saturday towards the Great Lakes and strong upper-level energy will support the outbreak of severe weather in the Mississippi Valley and perhaps as far north as the Ohio Valley.
