Episode narrative: A trough across the Rockies underwent lee cyclogenesis, pulling a warm front north into Iowa in the afternoon. While a few storms developed along the warm front, most development was along the later cold front that moved across the area in the evening. These storms were frequent hail producers, with many reports of baseball sized hail or larger. A tornado also occurred which resulted in damage to a few homes, out buildings, and trees.

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 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.

Episode narrative: The approach of an upper level storm system through the Four Corners, in combination with a gradual return of Gulf of Mexico moisture, a tightening dryline, and lifting warm front triggered scattered thunderstorms on the afternoon and evening of the 25th. The initial thunderstorm development was concentrated across the southwestern Texas Panhandle as well as the western South Plains, in close proximity to the warm front and dryline. The most intense storm of the day evolved from a cluster of thunderstorms over the southwestern Texas Panhandle during the late afternoon hours. Once the storm became organized it began rotating and took a right turn. The southeast track of the supercell brought the thunderstorm across Tulia (Swisher County), just northeast of Floydada (Floyd County), and eventually through McAdoo and Dickens (Dickens County) before finally weakening over far southeast Dickens County late in the evening. During its greater than six hour trek, the supercell thunderstorm was a proficient hail producer, tossing hail as large as baseballs, softballs, and even grapefruit size. The large to giant hail caused significant damage around the region, including Dickens, which took a direct hit. Windows were smashed out of homes and vehicles, while roofs and siding incurred large impact craters. The hail-producing thunderstorm occasionally generated intense straight-line winds too. A Texas Tech University West Texas mesonet site near McAdoo measured a peak wind gust of 90 mph. In addition to generating very large hail and damaging winds, the supercell produced one brief tornado near Dougherty, in a rural area of southeastern Floyd County.

Event narrative: On Saturday afternoon at 1:58 PM EDT, an EF-0 tornado touched down in Poolesville, MD. This tornado was brief, only being on the ground until 1:59 PM EDT. It had estimated 75 MPH winds with a path length of 0.4 miles and path width approximately 50 yards.

Damage was sporadic along its path. The first evidence of damage was near the intersection of Fisher Avenue and Spates Hill Road, where a residence in the 17000 block of Spates Hill Road had three cedar trees blown down in a unidirectional orientation. This was likely the rear flank downdraft of the storm that initiated the formation of the tornado..

The first evidence of tornadic damage was in the 17100 block of Campbell Farm Road. Here, several single family home residences suffered tree damage, with downed and snapped trees, along with an air conditioning unit and a temporary metal trailer moved from their foundations.

The tornado briefly lifted before producing damage to trees near the intersection of Wootton Avenue and Hempstone Court. Here, large limbs of trees were snapped in different directions, along with trees being uprooted in a direction opposite of the storm motion.

The tornado briefly lifted, before touching down again for the final time at the interface between the western portion of L.M. Stevens Park and the backyards of several single family homes along the 19100 block of Dowden Circle. Here, there were two softwood trees uprooted falling to the northwest, with another softwood tree snapped. One utility shed was damaged by a tree that fell onto it. One home incurred damage with a large limb that blew onto the deck. A wooden fence was blown over to the northwest. Leaf debris was observed on all four sides of one of the residences. An apple tree was snapped, with the losse top coming to rest towards the east, which was the opposite direction of other damage in that immediate area.

Event narrative: A National Weather Service Melbourne damage survey confirms that a brief EF-0 tornado touched down initially in the River Groves mobile home community in Micco. The tornado continued to the east- southeast into the Summit Cove Condominiums complex before crossing US-1 and emerging into the Indian River Lagoon near the Sebastian River Marina and Boatyard. The tornado was on the ground for approximately 0.5 miles, had a maximum width of approximately 100 yards, and peak winds estimated between 65-75 mph.

Damage was first noted near Love Ct. where the tornado touched down at approximately 536 pm EDT. Brevard County Emergency Management conducted an initial assessment and documented between 25-30 structures with at least minor damage in the River Groves community, primarily along Love Ct., Cherish Dr., and River Groves Dr. These homes suffered partial damage to carports, awnings, siding, and skirting. Additionally, several structures lost portions of their roof when the attached carport or porch awnings were torn away from the home.

The tornado continued east-southeast toward the Summit Cove Condominiums complex where some damage was noted to trees near the clubhouse, as well as siding on nearby homes, on Summit Cove Dr. The system crossed US-1 before emerging into the Indian River Lagoon near the Sebastian River Marina & Boatyard, where several boats were moved from their storage rack. An eyewitness indicates the tornado briefly became a waterspout before dissipating.

There are no known direct injuries or fatalities as a result of the tornado.
Episode narrative: A disorganized area of showers and some embedded thunderstorms tracked into southeast Michigan during the late morning hours of April 1st, 2023.  While the overall environment was marginal owing to lack of instability, locally favorable conditions for severe weather developed south of I-94 as upper and low level features briefly interacted. The thunderstorm complex reinvigorated between 10 and 11 AM, eventually becoming severe for a brief period over Lenawee/Monroe/southern Wayne Counties. These storms produced damaging wind gusts, sub-severe hail (spotters reported up to M&M size), and a brief/weak EF-0 tornado in Dundee. The tornado was on the ground for 5 minutes, causing damage consistent with 80 MPH wind gusts as it tracked through the heart of downtown Dundee. By noon, storms had shifted into Canada and the severe weather threat was over.
