Episode narrative: A powerful storm system, with highly anomalous magnitudes of wind shear and moisture for late February, impacted the forecast area on the evening of the 26th. A broken line of severe thunderstorms developed across the eastern Texas Panhandle/far western Oklahoma and quickly swept through much of the forecast area. Widespread wind damage, including gusts near 90 mph, along with a record number of tornadoes (13) for February occurred. Several reports of large hail were also received. Behind the line of thunderstorms, a tight pressure gradient and strong westerly low-level jet allowed widespread 50-60 mph winds gusts to continue through the late evening hours.

On the east side of Highway 431, near the Lincoln Road intersection, numerous structures were heavily damaged including multiple stores which sustained major damage. This includes a collapse of walls and roofs displaced with debris thrown eastward. Given the degree of damage at this location, a mid-range EF-3 rating was reported.

Episode narrative: A very strong system developed on the morning of March 31st and tracked across the state of Iowa. This system pulled unseasonably warm and moist air into the Midwest, which combined with a very favorable wind profile to create a volatile environment for severe thunderstorms.  Discrete supercell thunderstorms occurred initially, but quickly transitioned into a QLCS mode. This system produced a historic tornado outbreak for the area, with a record 29 tornadoes on the day, including 13 rated EF-2, 1 rated EF-3, and 1 rated EF-4. This was the first EF-4 tornado in the NWS Quad Cities service area since 1995. 11 injuries were reported, with no known fatalities. In addition to the numerous tornadoes, there were many large hail and damaging wind reports. Maximum straight line thunderstorm winds were estimated at 80 to 90 mph.

Event narrative: A tornado tracked out of Madison County, Alabama into Lincoln County after crossing Borderline Road. The tornado's estimated peak wind of 160 mph was noted at the intersection of Borderline Road and Myers Road where a newly constructed, however not completed, home was destroyed with a complete collapse of walls. The degree of damage at this location was slightly lowered below expected values due an uncertainty in the status of the garage, which was facing west. The tornado paralleled Borderline Road as it continued east-northeast. Sporadic trees were uprooted and snapped south of Vanntown, crossing Hester Creek. The tornado with a peak wind speed of 143 mph destroyed several farm outbuildings housing farm equipment from Mason Road eastward onto Echols Road. The tornado was weakening at this point, and finally lifted just after it crossed John Hunter Highway (Highway 122) just south of Elora in far southeastern Lincoln County. Tin was strewn into an open field in this location, but no further tree or structural damage was noted beyond the tree line near Collins Road and Mountain Road.
Episode narrative: A strong storm system led to significant impacts. Heavy rainfall amounts of 3 to 4.5 inches produced isolated flash flooding of roads. Very strong wind gusts occurred, ranging between 50 and 70 mph. These were associated with both thunderstorms and gradient winds afterwards. The line of storms moved through during the early afternoon, and then very strong gradient winds continued for hours afterwards through the afternoon. The magnitude and duration of this wind produced significant damage to trees, power lines, and outbuildings. Soggy ground due to the excessive rainfall likely contributed to some trees being more susceptible to being blown over. Numerous power outages occurred. Two tornadoes occurred along the line of thunderstorms across southwest Indiana, both on the west and northwest sides of Evansville. Finally, the lowest barometric pressure of all-time was observed in Evansville (976.0 mb). The center of the low tracked from the bootheel of extreme southeast Missouri northeast right along the Ohio River. Very strong southwest winds occurred on the back side of the low pressure system.

In addition to the damage to the church, several homes received minor roof and fascia damage, and dozens of trees suffered major limb damage or were uprooted or snapped at the base. Peak winds were estimated near 100 mph.

Event narrative: An intermittent tornado damage track was noted along the west flank of a focused and elongated area of downburst winds. Initial damage was to a center pivot and three wooden double-posted electrical transmission structures. After that, the damage was largely to trees although there were a couple of farm outbuildings damaged along the track. One east- west oriented tree line had a focused damage area approximately 200 yards wide. it appears likely that this tornado track had some gaps in it based on the somewhat sporadic damage pattern. Special thanks to Stanton county emergency management for their assistance in this survey and drone-based evaluation.
