1959: Aberdeen recorded a high temperature of 102, which is the earliest date that Aberdeen reached 100 degrees.

1967: The latest blizzard ever record for South Dakota ended on this day. Snowfall amounts in the west were generally 5 to 12 inches with a 16 inch report in Lemmon and 30 inches in the northern Black Hills. Winds of 40 to 50 mph caused blowing snow which occasionally reduced visibility to near zero and snow drifts of 4 to 5 feet. Other snowfall amounts include, 5 inches in Murdo and 6 miles SE of McIntosh; and 4 inches in Timber Lake.

1997: Heavy rains of 1.5 to 2.5 inches with an isolated 4.5 inch report fell over central South Dakota and caused flooding to several creeks, streams, low-lying areas, and roads. This early May rain only aggravated the areas flooded in March and April. Lyman County experienced the most significant flooding where 4.5 inches of rain fell, north of Vivian. Part of a golf course was flooded and some personal property was flooded along with the KOA campground near Kennebec. Some rainfall amounts include, 2.5 inches 7 miles NW of Presho, and 2.01 inches near Stephan.

1895: An F5 tornado went on a 22 mile rampage from the northwest corner of Sedgwick County to 6 miles northwest of Newton in central Kansas. The almost one mile wide behemoth killed 8, injured 25, and devastated 25 farms, a few of which completely vanished. Debris was carried for many miles and dead livestock were found everywhere. Four fatalities occurred in each of 2 families who had hesitated to take cover. It is possible they didn't recognize the nearly 1 mile wide funnel as being

a tornado.
