Event #1:  June 2, 2010 Bow Echo

Bow echo passed through in the early morning hours of Wednesday, June 2.

There were two corridors of wind damage from eastern Illinois to western Indiana.

One veered north of our area & affected areas from Bloomington & Kankakee, Illinois to Chesterton, Indiana.  The other occurred in a discontinuous fashion from Champaign to near Danville, Illinois & from near Montmorenci to Lafayette & north of Frankfort, Indiana to north of Kokomo.

The pockets of damaging straight-line winds from Wednesday morning’s squall line were caused largely by a layer of dry air in the mid-levels of the lower atmosphere.  Where this was most pronounced & instability was the highest, the wind was maximized.

It also appears that a slight inversion or lid at the mid-levels may have blocked some of the damaging winds from reaching the ground.  This is seen below in this sounding from central Illinois:

(Sounding is a look at the lower atmosphere from top to bottom via an air-born balloon/sensor).

When rain & wind associated with a t’storm downdraft move through a dry layer, part of the rain evaporates, the air cools further & the wind accelerates faster towards the ground with weight.

This is often how micro & macrobursts occur.  Wednesday morning’s wind appears to be a longer, occasionally sporadic corridor across Tippecanoe & northern Clinton counties, rather than a localized, circular or oval pattern with debri fanning out (consistent with a micro or macroburst).  The 60 mph gust at Delphi Friday appeared to be a microburst due to tree/tree branch orientation & local nature of the wind damage.

Severe Weather Reports:

Tippecanoe County:

5 Miles West of West Lafayette: 60 mph gust estimated.

Lafayette: 70 mph gust estimated near Greenbush.

Several trees uprooted with one on a home.

Windows blown out of several apartments.

High-tension power poles bent over.

Numerous branches downed.

Carport roof removed.

Several homes with minor roof damage.

Clinton County:

Near Mulberry:

Heavy damage to hog farm with debri strewn over an acre (75 mph gust estimated)

Trees & tree branches downed.

4 Miles North of Frankfort: 50 mph wind gust estimated.

South of Rossville: 58 mph Wind gust estimated.

Howard County:

1.5 Miles South of U.S. 31/U.S. 35 Intersection Northside of Kokomo: 55 mph wind gust measured.

County Road North 80 West & County Road West 300 Northwest Side of Kokomo: 58 mph wind gust estimated.

Corridor of straight-line winds caused heavy damage to the Mike Burkhalter farm.  There was heavy structural damage to hog barns in his operation near Mulberry, in northern Clinton County.  Most of the structures are a total loss.

Given the nature of the twisted sheet metal, splintered wood & distance debri was blown, these winds were around 75 mph.  To cause this much destruction to such newer constructed buildings would take a near or right at hurricane force gust.  Debri was blown in one single direction:  west to east.

Event #2:  June 4, 2010 Supercells & Wolcott Tornado

Two long-track splitting HP supercells passed through the WLFI viewing area on the evening of June 4, 2010.  Mid-level rotation was observed frequently with 2 instances indicating low-level rotation via radar & ground observation with the cells.

A wall cloud was observed several times when low-level rotation was observed on radar & an EF0 tornado touched down northeast of Wolcott.

Several bursts of damaging wind occurred via front-flank & rear-flank downdrafts.

Severe Weather Reports:

Cass County:

1 Mile North of New Waverly: 40′ tall by 3-4′ diameter tree fell into a house.  Bathroom & three bedrooms were severely damaged.  No one was home at the time.

North & Southeast of New Waverly: Several trees/tree branches down.

New Waverly: Multiple trees down.

New Waverly: Pea-sized hail reported.

Miami County:

Southside of Peru: Tree fell on a car occupied by several people.  No information on injuries.

Peru: Trees & powerlines down across the city.

Between Peru & New Waverly: Tree branches down, power lines down

Peru: Pea- to dime-sized hail reported.

Peru: Large limbs down at Maconaquah Park golf course.

South of Peru: Greenhouse damaged by hail.

South of Peru: Some crops flattened.

White County:

Near Monon: 60 mph wind gust estimated.

Near Wolcott: Rotating wall cloud reported.

Northeast/East of Wolcott: Tornado touchdown reported.

Northeastern Prairie Township: Rotating wall cloud reported & confirmed through photographs.

Carroll County:

5 Miles East of Camden: Roof blown off barn

6 Miles East-Southeast of Camden: Semi Trailer Blown Into a Ditch

Aaron Hutsell took these great pictures of the rotating supercell in southeast White County, moving into Carroll County.

Aaron caught some spectacular cloud-to-ground lightning pictures!

No doubt about it, there was a potentially tornadic supercell in southeast Jasper, northwest White, southeast White & in Carroll County tonight.  The reports, photos & radar data indicate that.

An EFO tornado did touch down northeast/east of Wolcott around 8:50 p.m. & stayed on the ground until 9 p.m., doing heavy crop damage between County Road 600 & 500.

The tornado lifted, but it continued to exhibit a wall cloud into Carroll County.

Ray Allie II caught this picture of the EF0 tornado near Wolcott at 8:55 p.m.

Here are more pictures from the tornadic supercell that produced the touchdown near Wolcott, as it moved into Carroll County a bit later.

Event #3:  June 5-6, 2010 Severe Weather Outbreak

Large HP supercells with large wedge tornadoes in Illinois & Iowa evolved into several small, bowing segments of straight-line winds with embedded tornadoes of EF0-EF1 strength in our area.  The strongest tornado in our viewing area was an EF3 in Miami County.  Only one hail report was received & that was golfball-size hail falling in Newton County near Lake Village.

The kicker to pop the severe weather was a surface low pressure, cold front & shortwave at the mid-levels that swung in from the northwest.  A shortwave is a cold pocket up in the atmosphere.

Strong winds in the atmosphere from the southwest & west contrasted with south winds at the surface, which created speed & directional wind shear.  Good directional shear was provided in the lowest 1 mile of the atmosphere, which was good for tornadoes.

A layer of dry air at the mid-level enhanced the damaging wind threat as vigorous, rain-soaked downdrafts via strong winds aloft fed down through dry layer, which only increased the wind strength.  Pockets of 60-80 mph winds occurred.

The air was very warm, tropical, juicy, buoyant & unstable with low cloud heights, which made it easier for tornadoes to form.

Precipitable water values were very high, so where it did storm, it rained very heavily.  This is a measure of how much water we have available in our sponge to wring out for rainfall.  Street flooding was reported in Monticello & a 3″ per hour rainfall rate was reported by Glen Means at his weather station in Miami County.

As the tornado passed to the north of the Grissom Air Reserve Base ASOS Weather Station, several notable data can be gleaned from the stations automatic observations.

1.  At the time the tornado was passing, the barometer pressure reading dropped 0.4 inches in 12 minutes!  It then rose back up 0.4 inches within 10 minutes after the passage of the tornado.  Tornadoes are concentrated areas of low pressure with quick, tremendous barometric pressure falls as they approach & pass.

2.  The wind direction swung from west-southwest to the north, to north-northwest to west-northwest to the west with consistent gusts of at least 52 mph.  The peak steady wind of 39.1 mph at 1:46 a.m. did not register a gust.  There may have been a malfunction from a very, very strong wind gust.  I am checking with the National Weather Service at North Webster to see if there is a back-up anemometer (wind gauge) at Grissom that could register the gust if the current station malfunctioned at that point.

A similar situation occurred in May 2008 at Carbondale, Illinois when the anemometer failed after reaching +80 mph, but a backup anemometer registered a gust to 106 mph.

Two EF1 tornadoes have been confirmed in Carroll County with winds of 100-110 mph.  Numerous structures were damaged/destroyed with numerous trees & powerlines downed.

Jeremy Houser of Radnor (Carroll County) took these picture of EF1 tornado damage near Rockfield (northwest of Camden).

Ashley Brodar took these pics of damage near Rockfield, as well.

These are damage pictures from east of Yeoman taken by Kris & Susan Smith of Burnettsville.

This damage pic from Yeoman was taken by Matt Dulin.

Two tornado have been confirmed in Cass County.  An EF1 with winds around 110 mph & an EF3 with winds of up to 135 mph.  Two pockets of damaging straight-line winds of 60-80 mph also occurred.  A home was heavily damaged by the straight-line winds near Galveston with tree & powerline damage.

One person was injured at Deacon when a mobile home was overturned by the EF1 twister with its 4.1-mile path.  Numerous trees & power poles were felled & many barns & farmesteads were heavily damaged or destroyed.  The EF3 developed quickly & moved into Miami County & carved a 7- to 8-mile path.

Audry Snavley took this picture of damage on the Carroll/Cass County line near Deer Creek.

EF0 tornado was confirmed northeast of Chalmers.  It approached EF1 strength as it moved to Lake Freeman.  EF1 strength was reached on the Carroll County line.  Structural damage occurred around Lake Freeman with trees & powerlines blown down.  Winds peaked at 85 mph with an estimated strengthening to 100 mph over Lake Freeman.  The tornado carved a 3.75-mile path before reaching Lake Freeman.

It appears straight-line wind damage occurred south & around Wolcott.  Some barn roof damage was reported tree & powerline damage was reported with 60-70 mph winds.

An EF3 tornado has been confirmed in southern Miami County.  U.S. 31 was closed by debri of trees & structures, as well as powerlines.  Winds were estimated at around 135 mph.

One home was destroyed & numerous other homes were damaged.  Several farm structures were damaged/destroyed with numerous trees & powerlines downed.

Brandon Craven captured these damage pictures near U.S. 31 in southern Miami County.

Audrey Snavely of Deer Creek (Carroll County) took this pic of heavy grain storage equipment that was tossed around like toys into this cornfield.

Tree & tree limbs were downed & crops downed/bent over by 60 mph straight-line wind core in area of northern Jasper County.

Core of damaging straight-line winds near the county line & produced wind damage near Wolcott.

Tornado damaged/destroyed homes from Dwight to St. Anne in Livingston & Kankakee counties in Illinois.  A low-level rotation couplet was seen via Precision in northwestern Newton County.

However, surveys indicate the tornado lifted 4.7 miles west of the Newton County line.  A funnel cloud likely continued well into Newton County, before dissipating just east of U.S. 41, judging by the radar data.

No straight-line wind damage was found/reported.

Brandon Redmond captured this shot of twin tornadoes near St. Anne (Kankakee County), west of the Newton County line.

  1. My daughter was married near St Anne, IL that day. We dodged the storms on the way home that night.
