As we told you by the end of last week, another round of severe weather (the first one was over Iowa on Saturday) will impact parts of the Ohio Valley from extreme southern Indiana and Ohio through extreme northeastern Texas on Sunday evening into the early morning on Monday.

There is a smaller area, mainly focused on northern Arkansas and southern Missouri, categorized as enhanced (in orange in our maps), or level 3 out of 5, where severe storms could produce a few tornadoes, some that could be strong, and damaging winds.

We expect the storms to increase in severity late afternoon into the evening once the atmosphere has gained lots of warmth and humidity streaming from the Gulf of Mexico and once it crashes with the cooler and drier air mass arriving from the northwest. Storms will become more organized and perhaps linear, producing damaging winds and a few tornadoes, which can be strong.

It is important that residents in the highlighted areas have their phones charged, have at least 3 ways of receiving weather alerts as well as know where to go in case a severe storm warning or tornado warning is issued for your location. Be sure your Weather & Radar app notifications are turned “on” too so that you can be notified if you are in a severe weather forecast zone.

Remember the safest place to be when in a severe thunderstorm warning or tornado warning is in a shelter (if available), or on the most central room, on the lowest level of your home, away from windows and doors that face the outside. These rooms are typically a closet or bathroom.

A good way to stay safe is to have bike helmets on and shoes on in case your home is hit by severe storms and in the path of flying debris.

This is part of the same system that struck Iowa on Saturday, combines with another low-pressure system that will move through the area increasing the risk of severe storms that will be moving over the Ozarks through the Ohio and Tennessee Valley through Tuesday. Expect the risk of severe weather to slide to the east on Monday, extending from Mississippi/Alabama to the northeast into the central Appalachians.
