As the storm started to shift east, the system quickly started to dissipate over the states of Alabama, Mississippi, Georgia, and Tennessee.

The states with the most fatalities were. The states with the most tornadoes were. The outbreak saw 4 enhanced risk days.

June 13
A storm that developed over the Pacific strengthened as it approached the West coast. As the storm was shifting over Canada, meteorologists predicted a shift towards the Dakotas and then down into the Plains. Severe thunderstorms along with golf ball-sized hail dropped and tornadoes were confirmed in Eastern Montana, and the Dakotas. As the storm strengthened, an EF5, with 205 mph winds, killed 2, and injured many more near Parshall, North Dakota.

June 14
On day 2, the storm shift southeast a little, causing up to a dozen EF4's, and over 2 dozen EF2 and EF3 tornadoes. Hail, measured up to 7 inches in circumference was recorded in multiple states. Isolated thunderstorms, along with tornadoes, caused multiple deaths. A few people were also killed by straight-line winds, lighting, and flooding. Snowing, up to 7 inches was also recorded in the Tri-State area. Flooding also played a big factor, with rain up to 6 feet in rural Oklahoma was recorded, as dozens of people and cattle were killed as the flooding was so severe that a state of emergency was declared.

Catastrophic damage was recorded along with 324 mph wind speeds. Dozens of other tornadoes were confirmed, including multiple EF4's and dozens of weak tornadoes. The storm started to gradually weaken as cold air masses collided along the stall boundary with warm air masses, causing the storm to weaken by 10%. However, the following day, more violent and deadly tornadoes were expected, but the storm started to shift southeast.

June 17
On day 5, dozens more events occurred as the storm was slowly, but gradually weakening, causing severe damage. Less violent tornadoes happened, but damage was still recorded. Severe rainfall along with weak tornadoes caused severe to minimal damage occurred. Dozens of significant tornadoes were also recorded, along with strong jet streams. However, the storm started to weak more as the stall boundary started to break off from the air masses. The storm had a 30% chance to produce a violent tornado for the last 2 days of the sequence.

June 18
On day 6 of the sequence, less violent and significant tornadoes occurred, however, death and damage was recorded. As the storm was rapidly dissipating, heavy rainfall occurred, causing dozens of flash floods, straight-line winds, and large portions of hail. Mobile home parks were reduced to destruction.

June 19


On the last day of the outbreak, mostly minor tornadoes touched down, however, a few significant tornadoes did touchdown. Another system from the storm did cause a few tornadoes to touch down out West, however, most were weak tornadoes. The storm had only a 5% chance of producing a violent tornado and a 20% chance of producing tornadoes. The 19th was the least active, least eventful, least deadliest, and least costliest day of the tornado outbreak sequence. Flash flooding along with huge sized hail was still present as the eye of the storm passed over New York City.
