Severe Weather Outbreak Continues Wednesday With More Tornadoes Possible In South, Midwest, East

Strong Tornadoes, 75-mph Winds Possible In South

Today is day two of a severe weather outbreak stretching from the South to the Ohio Valley and mid-Atlantic states that already spawned multiple destructive tornadoes, giant hail and damaging winds in the Midwest and Plains Tuesday. This is happening less than a week after an outbreak of 24 tornadoes swarmed over many of the same areas.

What Happened Yesterday

About 210 reports of severe weather were received by the National Weather Service Tuesday through early Wednesday morning, the most of any 24-hour period in the U.S. since July 28.

The most heavily damaged areas were from one supercell thunderstorm which tracked over 120 miles in almost 4.5 hours from northeast Illinois into northern Indiana. That supercell spawned destructive tornadoes in Kankakee, Illinois; Lake Village and Wheatfield, Indiana, according to the National Weather Service.

This supercell also dumped giant hail from 5 to 6 inches in diameter in or near Buckingham, Campus and Kankakee, Illinois. This may have set a state hail record, something an ad hoc committee of meteorologists will examine at a later date.

A second supercell thunderstorm tracked into Chicagoland, dumping 3 to 5-inch diameter hail in the far southwest suburbs of Bolingbrook and Darien, then half-dollar size hail downtown at the Loop.

Elsewhere, hail up to baseball size pelted the western Oklahoma City metro area from a tornado-warned supercell thunderstorm. Several severe thunderstorms pelted the Kansas City metro with hail up to 2 inches in diameter.

At least two tornadoes touched down in western Texas, one just southeast of Abilene and the other just east of Laughlin Air Force Base near Del Rio.

Flash flooding stranded vehicles in Grand Rapids and near Holland, Michigan.

Happening Now

A line of severe thunderstorms is sweeping into the Ohio Valley. Gusts of 65 to 70 mph along with power outages were reported in parts of southern Illinois early this morning as the line swept through. Trees have been downed and power outages reported in parts of Illinois and Indiana. Scattered severe storms are also flaring up in parts of the South.

Here are the latest radar views of what's happening right now, with any watches and warnings in effect from the Midwest to the South.

Wednesday

In general, Wednesday's primary severe threat will be damaging thunderstorm wind gusts from parts of the Appalachians and mid-Atlantic to the lower Mississippi Valley.

However, some tornadoes are expected, and we can't rule out a stronger (EF2+) tornado in the upper Ohio Valley, northern Appalachians and lower Mississippi Valley.

Thunderstorms, some of which may be severe, will persist into the night in the Southeast from the mid-Atlantic, Appalachians and Tennessee Valley to the northern Gulf Coast.

Thursday, only a few severe thunderstorms are possible near the Southeast coast and Florida before the cold front sweeps through.

Flood Threat

Along with the severe threat, these storms may also bring heavy rainfall. Some of these areas saw heavy rainfall from last week’s storms, so rain will be falling on already-soggy soil in some cases.

Another 1-3 inches of rainfall is possible, with higher totals expected across areas where slow-moving storms train over the same location for a few hours. Local flash flooding is possible.

Prepared, Not Scared

You can stay as safe as possible during severe thunderstorms by following these general tips:

- Have multiple ways of receiving official watches and warnings from the National Weather Service, including from your smartphone and from NOAA weather radio. Make sure your smartphone and NOAA weather radio are fully charged and notifications are turned on, in case a warning is issued while you're sleeping.

- Before a storm threatens, determine where the best place to take shelter is when a warning is issued where you live. If you live in a manufactured home, you should consider where the nearest community storm shelter or nearby home is that you can get to quickly.

- When a warning is issued, take shelter immediately, including for severe thunderstorm and tornado warnings. Don't waste precious time looking out a window. Some tornadoes are hidden by rain or may not be visible at night if lightning isn't frequent enough.
