April 11, 2008:

An intense area of low pressure moving northeast across the Central Plains brought widespread heavy snow and strong winds to parts of central and northeast South Dakota. Snowfall amounts from 3 to 16 inches combined with north winds of 30 to 45 mph brought widespread blowing and drifting snow with blizzard conditions and heavy drifting affecting much of the area. A few thunderstorms also occurred, bringing rapid snowfall rates to some areas. Many vehicles went into the ditch with many other accidents occurring. Most roads became nearly impassable with no travel advised for parts of central and much of northeast South Dakota. There were many people stranded to wait out the storm. Also, many schools and businesses were closed on Friday the 11th.

U.S.A and Global Events for April 11th:

1965: Severe thunderstorms in the Upper Midwest spawned fifty-one tornadoes killing over 250 people and causing more than 200 million dollars damage. Indiana, Ohio and Michigan were hardest hit in the "Palm Sunday Tornado Outbreak". Although no F5's were officially reported, at least 22 were rated as F3 or F4. This is the third deadliest day for tornadoes on record, behind the Super Outbreak of 4/3/1974, and the outbreak that included the Tri-State Tornado of 3/18/1925. Dr. Ted Fujita discovered suction vortices during the Palm Sunday tornado outbreak. It had been believed the reason why tornadoes could hit one house and leave another across the street completely unscathed was because the whole tornado would "jump" from one house to another. However, the actual reason is because most of the destruction is caused by suction vortices: small, intense mini-tornadoes within the main tornado.

1988: Sixteen cities in the western U.S., nine in California, reported new record high temperatures for the date. Afternoon highs of 95 degrees at Sacramento and 96 degrees at Bakersfield, California were the warmest of record for so early in the season.

1989: Forty-four cities in the south central and eastern U.S. reported new record low temperatures for the date. Lows of 25 degrees at Conway Arkansas, 29 degrees at Dallas/Fort Worth Texas, and 22 degrees at Ozark Arkansas, were April records. Lows of 26 degrees at Hot Springs Arkansas and 31 degrees at Shreveport Louisiana equaled April records.

2012: The deluge began around 3:30 a.m. Over the next few hours, fast-moving hailstones pummeled the area north of Amarillo, Tex., which had lately been sitting in dust due to a lack of precipitation, according to the news organization. The hail mixed with melting hail turning the dust to mud and the mix create four-foot high mounds that shut down a major highway for the next 18 hours.
