The storm near Columbus last week that killed 2 people and injured 4 has been ruled a “microburst”.  A microburst is a localized band of straight line winds.  A fast gush of air gets dropped from a thunderstorm cloud, hits the ground, and then spreads out.  Microbursts can produce damage as bad or worse than a tornado in some cases, and is a huge issue pilots have to occasionally deal with.

Here is a link to the National Weather Service’s full report:

EDGERTON, OH (WTOL) - The fire department says strong winds from a thunderstorm caused a 10′ brick wall to collapse, killing a construction worker.   The wall was part of the new school being built in Edgerton. It’s a preschool through eighth grade building that was scheduled to open in the fall of 2011.   Storms passed through Williams County around 11 a.m. The worker was pronounced dead at the scene.

Severe storms tracked through Indiana between 10-11 am EDT and weakened slightly as they moved into western Ohio.  Radar estimates of winds for the storm near Edgerton showed wind gusts around 50-55 mph.  (Severe thunderstorm warnings are issued when the winds hit or exceed 58 mph).

1:30 pm:  Severe storms exiting south out of Hardin county.  The rest of the tstorm watch should be cancelled after about the next hour.

12:50 PM:  T-storm warnings for Allen/Hardin counties.   Gusty storms elsewhere with heavy downpours.

12:20 PM:  Strong/severe storm now moving through Allen county.  Potential for some wind damage there.  The remaining storms on radar not currently severe.  Just very heay rain with gusty winds…although a few gusts may hit 40-50 mph briefly.  Severe threat will wane over the next few hours.

10:35 AM:  Severe thunderstorm watch until 4 pm for the following counties:  Allen, Crawford, Defiance, Erie, Fulton, Hancock, Hardin, Henry, Hillsdale, Huron, Lucas, Ottawa, Putnam, Sandusky, Seneca, Williams, Wood, Wyandot

10:15 AM:  The National Weather Service will be issuing a severe thunderstorm watch for NW Ohio.  A line of strong storms is moving through eastern Indiana, and will track across the area between 11 am and 1 pm.

Storms may contain large hail and strong winds.   Heavy downpours will accompany any storm that moves through your area.

5:45 pm update – severe storms are moving out.   Reports of trees down have come in from southern Michigan and the greater Toledo area.  Things will quiet down the rest of the evening.  We will dry out overnight, and stay dry Thursday and Friday,

Previous post:

A severe thunderstorm watch has been issued until 8 pm for much of the area.  Some lines of storms will track through the area, and some may produce high wind gusts. Storms will not hit everywhere.

With it being so muggy again, storms will unleash heavy downpours.  Storm threat diminishes later this evening, and should end after midnight.

The threat for severe storms will last into Saturday night.  Storms should diminish by Sunday morning, leading to a much more tranquil and comfortable pattern Sunday into Monday.

Storms may produce high winds and large hail.  With the very high humidity, torrential downpours will occur with the storms.  It will be possible to pick up an inch of rain in less than half an hour.  Repeated storms could cause rain totals of a few inches.

The heat index is how a combination of temperature and humidity really feels to your body (aka apparent temperature or the “feels like” temperature).

On our main weather page, under the 7-day, you will find current conditions for some cities in the area.  Plotted next to the temperature is the “feels like” heat index temperature.

Here is a link to the National Weather Service’s heat index chart.  You can find the heat index by using temperature and either dew point or relative humidity.  It is better to use dew point, since as the temperature changes, the relative humidity changes a bit over just a few hours.

After we reached dew points in the 70-75 range Thursday, they should drop to near 60 by late Friday, but will return into the low and mid 60s over the weekend.

WINDS ESTIMATED UP TO 105 MPH WERE NOTED ALONG WALTZ ROAD  AND JUST TO THE EAST. DAMAGE INCLUDED MULTIPLE HOMES WITH  ROOF DAMAGE AND TWO DESTROYED GARAGES. THE TORNADO ENDED  JUST EAST OF RUST RD.

*** 1 FATAL, 4 INJURED *** WIND DAMAGE TO FORT TRODD  CAMPGROUND. SEVERAL CAMPERS OVERTURNED AND THROWN INTO  POND.

The threat for thunderstorms will increase this afternoon into this evening as a cold front gets a little closer.  The air mass ahead of this front will be hot and muggy. 

Lines of storms will track through the area, and these storms may be severe.  The primary threat will be strong winds.  The tornado threat is very low, but an isolated tornado cannot be completely ruled out.

A National Weather Service (NWS) storm survey confirmed a tornado touched down just north of the Cone Rd exit off US 23…about 2 miles south of Milan, at 10:06 PM June 23. The tornado lifted about 2 1/2 miles northeast of Maybee, near Steffas Rd between Scofield and Zink. The total path length was 11 1/2 miles with an average path width of 50 yards.

The tornado was rated an EF0 along most of its path, producing winds of 60 to 70 mph. However, EF1 damage with winds estimated at 90 mph was found near Tuttle Hill Rd in London Township — a roof was torn off of a pole barn, and substantial tree damage was found. The width of this tornado had briefly extended to 100 yards in this location. Several homes also had roof and shingle damage – mainly in and near the town of Scofield.

The storm survey also indicated that straight line wind damage occurred to the east of where the tornado lifted and continued into the Newport area. This damage included some downed power lines, minor tree damage and plastic covering removed and aluminum frame damage on a green house.

The NWS in Detroit has put together a full page about the tornado here.
