A line of severe thunderstorms moved through the region during the overnight/early morning hours of July 1st, 2014. Widespread straight-line wind damage resulted across much of northern Indiana and southwest lower Michigan before the storms weakened over northwest Ohio. In coordination with local emergency management across most of our counties, damage surveys were completed in the hardest hit areas. 11 tornadoes have been confirmed with straight-line wind damage determined to be the cause in other locations across northern Indiana and southwest lower Michigan. An overview of the damage survey can be found here.
Widespread wind damage was reported from Iowa all the way into eastern lower Michigan. Several tornadoes have been confirmed via damage surveys over the past few days. Hail reports were mainly contained to Iowa although a few large hail reports did come in from Illinois and Indiana.
As of 4 pm EDT July 4, 2014, 11 tornadoes have been confirmed in northern Indiana. 10 of these were rated EF-1 and one was rated EF-0. Other damage surveys across the area revealed significant straight-line wind damage. The details for each tornado, including path maps, and wind damage surveys follow. This information is released in a Public Information Statement. The latest statement is available here.

A TORNADO TOUCHED DOWN JUST WEST OF LAGRANGE ON U.S. 20 AROUND 130 AM EDT...WHERE TREE LIMB DAMAGE WAS OBSERVED. THE TORNADO TRACKED EAST TOWARD LAGRANGE...UPROOTING AND SNAPPING TREES AS IT ENTERED THE TOWN SOUTH OF THE HOSPITAL. NUMEROUS TREES WERE UPROOTED AND SNAPPED JUST WEST OF S COUNTY ROAD 00 E BETWEEN U.S. 20 AND GRANT STREET.

A strong low pressure system was moving across the region during June 30th - July 1st. The local area was situated to the west of a cold front in what we call the "warm sector," an area with very moist and unstable air due to southerly winds. There were essentially 2 lines of severe storms that affected the western Great Lakes region on June 30th into the early morning hours of July 1st. Severe thunderstorms fired across eastern Nebraska on the afternoon of the 30th and quickly grew in size and strength as they formed a line and moved eastward into Iowa and eventually northern Illinois. Widespread wind damage was observed with this line of storms, especially across northern Illinois. This line eventually ran out of steam and dissipated as it moved into northwest Indiana. Some sporadic tree damage and hail reports were received over Berrien, LaPorte, and St. Joseph (IN) counties. These storms left an outflow boundary as they dissipated that stalled west to east along a line from Winamac to Warsaw. This boundary would help to feed the second line of storms later.
As this first line was decaying, a second round of severe thunderstorms rapidly fired, expanded, and intensified back west through eastern Iowa and northern Illinois. The enviroment was still very favorable for severe weather across this region which allowed for these storms to quickly congeal into a line and move to the east, approaching the local area. Unstable air and substantial wind shear allowed for these storms to progress into northern Indiana and southern Michigan during the overnight hours from June 30th into July 1st. Widespread wind damage occurred across most of the area along the leading edge of the line of storms. Weak to moderate circulations on the leading edge of the storm also produced several weak tornadoes in northern Indiana. These storms became wind dominant across eastern Indiana and eventually weakened across portions of western Ohio.
To sustain themselves and become severe, thunderstorms need heat and moisture (which creates instability), wind shear (strong winds that change direction with height), and forcing (such as a cold front). Environments necessary for thundstorms are typically found in the Midwest from late spring through summer. For this particular event, there was enough instability and strong wind shear present ahead of a cold front to produce thunderstorms that quickly became severe. In this case, the line of severe storms was in the form of what meteorologists call a quasi-linear convective system or QLCS. The system lasted long enough to be deemed a "derecho" by the Storm Prediction Center. The image below is courtesy of the Storm Prediction Center.
The images and descriptions below give a depiction of the mesoscale atmospheric conditions present at 11 pm EDT (03Z) on Monday, June 30th just before the line of storms moved into the area.

| Surface analysis (3Z) shows a cold front to the west near the IA/IL border. Surface dew points ahead of the front were in the 70s providing moisture to fuel the thunderstorms. |
850 mb analysis shows a low-level jet (~25-45 kts) pumping warm, moist air into the area ahead of a low pressure center. This helped to fuel and sustain thunderstorms as they developed in northern IL and moved into the local area. |
500 mb analysis shows a mid-level trough of low pressure, just to the west of the local area. This, coupled with a mid-level jet stream rounding the base of the trough, provided forcing for the thunderstorms to fire to the west before moving into the local area. |

| Effective Bulk Shear: A measure of the difference between winds at the surface and aloft in the atmosphere. Supercells and/or tornadoes become more probably as the effect bulk shear vector increases in magnitude through the range of 25-40 kt and greater. Values across the local area were in the 30-50 kt range. |
0 - 1 KM Storm Relative Helicity (SRH): SRH is a measure of the potential for rotating storm cells. Values of 0-1km SRH greater than 100 m2/s2 suggest increased threat of tornadoes. Values across the local area were in the 150-300 m2/s2 range with storm motion of 30-35 kts. |

The NWS Northern Indiana issued 7 tornado warnings and countless severe thunderstorm warnings as the line of storms moved across the area into NW Ohio. The severe thunderstorm warnings indicated the likelihood of 70-80 mph winds and used the "Tornado Possible" tag at the bottom of the warnings. Below is a portion of a severe thunderstorm warning issue during the event with pertinent parts highlighted in red.
