Severe Thunderstorms, Including Tornadoes, Likely In Midwest Thursday

Few Tornadoes, Large Hail, Damaging Winds Possible

Severe thunderstorms, including the threat for a few tornadoes, are once again in the forecast for parts of the storm-weary Midwest Thursday, the latest round in a March of multiple outbreaks.

Some of the fuel for these severe thunderstorms will be record heat for late March feeding eastward from the Plains. You can read about this extended record March heat wave here.

A tornado watch (the red polygon on the map below)is in effect for northern Ohio, western Pennsylvania and the West Virginia Panhandle until 11 pm EDT.

A severe thunderstorm watch (the yellow polygon on the map below) is in effect for far southeast Iowa and northern portions of Illinois and Indiana until midnight EDT.

Here’s what the radar across the Midwest looks like right now:

Thursday’s Forecast

What’s The Timing?

Severe storms have developed across the Great Lakes and are tracking south.

A few storms may also develop as far west as parts of Kansas, but that’s more uncertain.

Through the overnight hours, we will have one or more clusters of severe thunderstorms sagging southward through parts of Illinois, Indiana, Ohio and into western Pennsylvania as a cold front pushes southward. Some heavy rain and thunderstorms will likely continue overnight in the Ohio Valley.

By the Friday morning commute, the rain and storms could stretch from Missouri to Pennsylvania.

What Are The Threats?

– Large hail, possibly up to the size of baseballs

– Wind gusts capable of tree damage and some power outages

– A few tornadoes, possibly up to EF2 intensity

– Localized flash flooding

Be Prepared

If you’re in the area shown above, there are three steps you can take to stay safe in severe weather:

1. Know where to seek safe shelter when severe weather strikes before the storm. If you live in a manufactured home, the safest place is probably either a designated community shelter or the closest building such as a church, industrial building or any building with reinforced concrete.

2. Have multiple ways of receiving official National Weather Service watches and warnings, including from your phone and NOAA weather radio. Make sure your devices are full charged in case you lose power and alerts are turned on to wake you up at night.

3. Seek safe shelter immediately when you receive a severe thunderstorm or tornado warning for your area.

Storm Fatigue

It has been yet another active March for severe weather in the U.S., including parts of the Midwest.

On March 6, four tornadoes struck southern Michigan, including an EF3 in Branch County killing three, an EF2 in Three Rivers and an EF1 tornado that claimed a life in Cass County.

Four days later, a lone supercell spawned five tornadoes across northeast Illinois into northwest Indiana, including the EF3 Kankakee, Illinois, tornado, which killed three.

Then on March 15, another 17 tornadoes were confirmed across central and southern Illinois.

And we just had a flare up of severe storms with hail and winds this past Sunday from Illinois to western Pennsylvania.
