Severe weather will once more be a concern for parts of the Midwest on Thursday. The severe threat has also shifted east, an now includes parts of Southeast. A large threat area extends from central Texas to northern Illinois to northern Alabama.

The main mode of severe weather will be large hail, high winds and frequent lighting. That said, a chance for a few isolated tornadoes isn’t totally out of the question.

Timeline

HRRR

With storms ongoing in the early afternoon, especially in eastern Oklahoma and central Missouri, storm coverage will only increase as the day progresses. The HRRR, a NOAA model just released for forecasting on Tuesday, shows a significant uptick in activity by 4:00 p.m. CDT. Places like Fort Smith, Ark., St. Louis, and Chicago can expect to be impacted around this time. That said, forecasting an exact time is difficult at best. So, it’s advisable to remain weather aware from now through the late evening hours.

Further south, strong storms could impact the Dallas-Fort Worth Metroplex around rush hour as well. Take that into account as you make your way home in these areas.

Some of the storms that do develop, especially after 2 p.m., could be discreet — a single, stand-alone cell — in nature. This is the point the tornado threat is highest, but numerous models indicate the cells will become semi-linear as the afternoon progresses. Why is this good news? Well, linear storm complexes are less likely to produce large and violent tornadoes. Embedded supercells within the quasi-line can still produce short-lived tornadoes, so keep that in mind.

Moving into the overnight hours, a strong-to-severe line of storms will push into parts of the Deep South. Locations like Houston, Memphis, Nashville and Jackson, Miss. should be weather aware through early Friday morning. The main threat form these storms will be hail and high winds. A a couple of brief, weak tornadoes are possible as well.

For overnight severe weather events WeatherNation meteorologists suggest you get a programmable weather radio. These life-saving tools will awaken you if a tornado warning is issued in your area, giving you lead-time to seek shelter. Weather radios can be found at electronic stores and most big box retailers. A good weather radio will set you back about $30.

NEVER trust outdoor sirens for your cue to seek shelter. Despite many myths, sirens are difficult to hear indoors and if power is severed, the system can fail. That’s why WeatherNation meteorologists suggest getting a weather radio.

WeatherNation meteorologists will be watching the progress of the storms in the coming hours and will bring you the most up-to-date information on-air and online.
