...NWS DAMAGE SURVEY FOR 05/23/19 THUNDERSTORM WIND EVENT

.OVERVIEW...A LINE OF SEVERE THUNDERSTORMS PRODUCED DAMAGING WINDS
ACROSS A LARGE PART OF NORTHERN INDIANA INTO NORTHWESTERN OHIO.
SEVERAL AREAS OF CONCENTRATED WIND DAMAGE OCCURRED WITH WIND
SPEEDS UP TO 70 MPH RESPONSIBLE FOR MAINLY TREE AND POWER POLE
DAMAGE. A FEW LOCATIONS RECEIVED DAMAGE THAT WARRANTED FURTHER
INVESTIGATION. BELOW IS SOME OF THE PRELIMINARY FINDINGS.

.PAULDING COUNTY OHIO THUNDERSTORM WIND

PEAK WIND /E/: 80-85 MPH
PATH LENGTH /STATUTE/: 0.1 MILES
PATH WIDTH /MAXIMUM/: 25 YARDS
FATALITIES: 0
INJURIES: 0

START DATE: MAY 23 2019
START TIME: 556 AM EDT
START LOCATION: 5.7 NE PAULDING OH
START LAT/LON: 41.193242/-84.500376

SURVEY_SUMMARY: A LARGE DAIRY COW BARN WAS SEVERELY DAMAGED,
LOSING OVER 75 PERCENT OF ITS ROOF STRUCTURE. NEARBY FARM
BUILDINGS SUFFERED MAINLY METAL ROOF DAMAGE. FARM HANDS REPORTED A
RAPID PRESSURE CHANGE AS THE STORM MOVED OVERHEAD WITH THE BARN
BRING PICKED UP AND DROPPED BACK DOWN. PICTURES, ALONG WITH DRONE
FOOTAGE PROVIDED BY THE PROPERTY OWNER SUGGEST THAT A CONCENTRATED
MICROBURST WAS THE MOST LIKELY CAUSE OF THE DAMAGE, WITH SPEEDS
OF 80 TO 85 MPH IN A NARROW SWATH. SOME OF THE DAMAGE SUGGESTS
THAT A GUSTNADO MAY HAVE FORMED ON THE LEADING EDGE OF THE WINDS
THAT HELPED ENHANCE THE LOCAL DAMAGE.

.OTHER DAMAGE THAT HAS BEEN INVESTIGATED

AREA 1: BETWEEN MIDDLEBURY AND SHIPSHEWANA INDIANA.

DAMAGE OCCURRED TO A LARGE SILO AT THE HERITAGE CREAMERY NEAR THE
ELKHART AND LAGRANGE COUNTY LINE. THIS WAS LIKELY THE RESULT OF
ANOTHER CONCENTRATED AREA OF WIND BETWEEN 70 AND 80 MPH.

AREA 2: HOWE INDIANA

EXTENSIVE DAMAGE OCCURRED IN AND AROUND THE HOWE INDIANA AREA.
WINDS OF 70 TO 80 MPH MAY HAVE OCCURRED IN SOME LOCATIONS,
ENHANCING THE DAMAGE.

IF ADDITIONAL DETAILS ARE DISCOVERED, WE WILL UPDATE THIS SUMMARY.

Environment

Thunderstorms rapidly formed across northern Illinois Wednesday evening. These storms consolidated and formed a large convective complex across east central Illinois. Initially, conditions were relatively stable across northern Indiana, southern Lower Michigan, and northwest Ohio in the evening. Late Wednesday night into early Thursday morning, a low level jet allowed the greater elevated instability across Illinois to shift eastward. The combination of moderate instability and strong wind shear allowed this convective complex to survive across all of the forecast area with several reports of wind damage and 60 to 75 mph wind gusts.

From a synoptic standpoint, conditions were favorable for storm development. The local area was located in a favorable proximity to the upper level jet across the Great Lakes region. In addition, mid level winds were strong allowing for storms to become organized and the severe threat long lasting. Despite these storms occurring during a generally unfavorable time for severe weather late in the night, higher dew point air near the surface was also advecting northward which was a favorable factor for maintenance of these thunderstorms.

Initially northern Indiana, southern Lower Michigan, and northwest Ohio were relatively stable during the evening hours. The following images show how quickly elevated instability surged northward during the overnight. This instability was aided by strong low level moisture transport.

CAPE (Convective Available Potential Energy) is parameter to describe how buoyant the atmosphere, and a measure of the updraft potential. DCAPE (Downdraft Available Potential Energy) is a comparable parameter, but instead measures the acceleration potential of downdrafts. DCAPE values at or above 1000 J/kg can indicate favorable environments for strong downdraft potential as was the case here. Effective shear values of 40-55 knots combined with the instability allowed for maintenance of the severe storms across Illinois into the local area.
