...1919...A tornado swarm in northern Texas resulted in the deaths of 64 persons. (David Ludlum)
...1929...A record heat wave hit the East, with New York City experiencing its earliest 85 degree reading. (Intellicast)
...1973...A severe storm brought high winds and heavy snow to Iowa. Belle Plain received 20 inches of snow, and 19 inches blanketed Dubuque, record totals for both locations for so late in the season. Snow drifts up to sixteen feet high closed highways. (David Ludlum)
...1987...A cold front crossing the Northern Plateau and the Northern Rocky Mountain Region produced high winds in northeastern Wyoming. Winds gusting to 69 mph at Sheridan, WY downed power lines and caused some property damage. (The National Weather Summary) (Storm Data)
...1988...Strong northerly winds ushered cold air into the north central U.S. The strong winds, gusting to 60 mph at Rapid City, SD and Williston, ND, reduced visibilities in blowing dust over the Dakotas. (The National Weather Summary) (Storm Data)
...1989...Two dozen cities in the southwestern U.S. reported new record high temperatures for the date. Phoenix, AZ equaled their record for April of 104 degrees established just the previous day. (The National Weather Summary)
...1990...Twenty-two cities reported record low temperatures for the date as readings dipped into the 20s and 30s across much of the eastern U.S. Freezing temperatures severely damaged peach and apple orchards in West Virginia, where prolonged mild weather since January had caused an early blooming of spring vegetation. State and Federal agencies estimated a 50 percent loss in production for peaches and "Delicious Red Apples". (The National Weather Summary) (Storm Data)
...1996...The first of two late season heavy snowfalls in only three days over the northeast dumped 12 inches of snow at Slide Mountain, NY, 10.2 inches, at Ashburnham, MA, and 7 inches at Falmouth, MA. The 6.1 inches at Binghamton, NY brought its seasonal snowfall total to 131.8 inches -- its snowiest winter ever. (Intellicast)
