Episode narrative: A high impact storm system moved across Northwest Kansas. The storm system produced an environment that was favorable for any of the developing thunderstorms to produce a tornado, which led to multiple tornadoes occurring on this day.  The strongest tornado was rated an EF-1 which caused damage to the high school in Weskan.  

Otherwise thunderstorms produced hail up to half dollar in size near Wallace, and wind gusts estimated up to 65 MPH near Campus.  The thunderstorms on this day were heavy rain producers, with rainfall amounts ranging from two to four inches.  This led to some towns having street flooding as the storms moved through.  One location near Weskan had flood damage a barn.

The repeated rounds of heavy rainfall over the Ludell area, combined with runoff being funneled into Beaver Creek from the area, caused flooding to occur at Ludell.  The flood waters also flooded the county road going east from Ludell that followed Beaver Creek to Herndon.

Event narrative: Multi-vortex tornado moved through Weskan,KS causing damage to the Weskan school, numerous trees, and additional damage to properties in town.
Episode narrative: A strong storm system led to significant impacts. Heavy rainfall amounts of 3 to 4.5 inches produced areas of flash flooding, with numerous road closures. The heavy rain drove the Ohio River above flood stage at Uniontown. Very strong wind gusts occurred, ranging between 50 and about 70 mph. These were associated with both thunderstorms and gradient winds afterwards. The line of storms moved through during the late morning and early afternoon, and then very strong gradient winds continued for several hours afterwards through the afternoon. An indirect fatality occurred the following day during cleanup operations. A 69-year-old man in Calloway County was killed when a large branch landed on him while he was cutting up the tree. The magnitude and duration of this wind produced significant damage to trees, power lines, and other outdoor property such as fences. Soggy ground due to the excessive rainfall likely contributed to some trees being more susceptible to being blown over. Numerous power outages occurred, some lasting into the following day. Six tornadoes occurred along the line of thunderstorms across western Kentucky. The strongest was rated EF-2 just south of Paducah. Finally, the lowest barometric pressure of all-time was observed in Paducah (977.7 mb). The center of the record strong low pressure system 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 the afternoon. Gusts were up to around 60 mph. A semi was blown over on Interstate 24 in Trigg County.

Episode narrative: A very strong low pressure system deepened over the central Great Plains beginning on March 31, 2023 and continuing into April 1st. As this storm system approached Middle Tennessee from the west, southerly flow at the surface resulted in plenty of moisture and warm temperatures for the area. This all helped to set up an early spring severe weather episode for the area. This system's accompanying cold front approached the Mississippi River late on March 31st. Thunderstorm activity ahead of the front across western Tennessee quickly turned severe, but this early activity tended to rapidly weaken as it crossed the Tennessee River where instability was not favorable. However, as the cold front approached Middle Tennessee and the low level jet strengthened, these thunderstorms were able to better sustain themselves. Numerous severe thunderstorms impacted Middle Tennessee through the early morning hours of April 1st. These thunderstorms produced large hail and damaging winds, while several thunderstorms also produced tornadoes. In total, four tornadoes were confirmed in National Weather Service Nashville's area. The most impacted area was Readyville along the Rutherford and Cannon county line were a strong EF2 tornado caused significant damage. As this event crossed over into a new month, this event will be continued in April 2023.

Event narrative: This narrative continues and concludes a tornado that began in far northern Trousdale County. Once this tornado tracked into Macon County near Rose Lane, property damage was found in the form of minor roofing and shingle damage along with a flipped propane tank as well as an outbuilding set on cinder blocks that was moved about 50 feet. The family that lives at the residence with the flipped propane tank had to temporarily evacuate due to a gas leak. The tornado strengthened as it approached Dixon Creek Road, and this is where the most significant damage was found with EF1 tornado damage and estimated peak winds of 95 mph. A residence here lost about 60 percent of their roof, six outbuildings on the property were completely destroyed, and multiple trees were uprooted. The tornado weakened after crossing Dixon Creek Road, causing minor roofing damage to barns and other outbuildings before it lifted at Sycamore Valley Road. Damages are estimated for Macon County.
