A garage suffered damage as the winds moved through a north facing door. The tornado crossed 1150 E and uprooted or snapped several trees with the winds picking up a porch and most of a roof on a 1 story home. The porch was thrown to the other side of the house and the roof lifted roughly 3 feet up and then set back down. Wall and roof damage has made house unsafe to be in. Damage was noted in corn field behind property with some tree and barn roof damage on 1250 E where the tornado appears to have lifted. Track Map Downloadable KMZ File

Wind & Hail:

We received reports of wind damage and hail up to 1" (quarter-sized). See the "Storm reports" section for details, and the photos section.

GIF of the weather between 3:30PM EDT and 4:30 EDT. Notice the storm's motion in White county.	A side by side image of reflectivity and velocity showing inbound and outbound velocities near each other, but it's pretty broad rotation.	The storm moves farther south and east closer to Burnettsville, IN around 3:35 PM EDT. Still pretty broad rotation.	The storm is just north of Burnettsville, IN as shown by reflectivity and velocity around 3:45 PM EDT.

Observations are collected from a variety of sources with varying
equipment and exposures. We thank all volunteer weather observers 
for their dedication. Not all data listed are considered official.

Environment

Most thunderstorms need a source of lift, moisture, instability, and wind shear. This section will detail the what was apparent with this event. 

Sources of Lift (weather pattern/boundaries) and Wind Shear

Figure 1: Vorticity or forcing mechanisms in the mid levels of the atmosphere. Wind flows from west to east in this image so out in front of the X's displayed in this map show where lifting is expected. Generally indicated by blue contours (3PM)	Figure 2: Surface mixing ratio at 4PM. This is a measure of surface moisture change over 3 hrs. Notice how the drier air mass is behind the storms. Sometimes drier air, because it's heavier than moist air, can force storms along.	Figure 3: Effective shear (3PM) across Northern Indiana shows the potential for some turning in the atmosphere with values over 30 kts.

Moisture/Instability

Figure 4: Elevation where condensation occurs as of 3PM. (LCL) When this value is less than 1000m and when combined with shear and instability parameters, there is a greater for tornadoes than if it is higher than 1000m above the ground level.	Figure 5: The rate of change of temperature between heights in the mid levels of the atmosphere (ML Lapse Rates) at 3PM. When this value, which indicates instability, is greater than 6 C/km, it can help to keep storms going.	Figure 6: Instability in the lower levels of the atmosphere (0-3km MLCAPE) at 3PM. When this value is greater than 75 or 100 J/kg enough instability exists for severe weather.
