Weather History - April 26th
Local and Regional Events:
April 26th, 1986:
Intense thunderstorms swept across southeast South Dakota, southwest Minnesota, and northwest Iowa. Baseball size hail fell in a 15-mile wide swath from near Pickstown to Scotland, South Dakota. The large hail caused extensive damage to windows, roofs, siding, and vehicles in the storm's path. Wind gusts of 70 to 80 mph and rain amounts of 2 or more inches in a short period (including 5 inches at Centerville) were reported in southeast South Dakota. Several tornadoes moved across northwest Iowa, including one that ran across part of Lyon County, destroying several farmsteads. Another tornado moved through Lyon County, Iowa, into Nobles County, Minnesota, damaging at least 16 farms. Another tornado touched down briefly on the south side of Okebena in Jackson County, destroying or damaging several houses.
April 26th, 1991:
During a severe thunderstorm, large hail fell over parts of Brown, Spink, Hand, and Buffalo Counties. Both Brown and Hand Counties received hail up to 1.75 inches in diameter.
April 25-26th, 2008:
An area of low-pressure brought widespread heavy snow of 6 to 20 inches to most of northeast South Dakota for much of the 25th and into the early morning hours of the 26th. The precipitation began as light freezing rain in the early morning across parts of the area before changing to all snow by mid-morning. Snowfall rates and north winds also increased as the low-pressure area intensified. The heavy snow combined with the high winds created widespread visibility problems and large snowdrifts. Snowfall amounts included 6 inches at Andover, Britton, Gann Valley, and 15 miles south of Miller, 8 inches at Roy Lake, 9 inches at Clark, Big Stone City, Hillside Colony, and Sisseton, 10 inches 7 miles south of Bristol, and 11 inches at Hayti. Locations with a foot or more of snowfall included 12 inches at Wilmot, Webster, and Waubay, 13 inches at Milbank, 15 inches at Castlewood, 16 inches near Victor and Summit, 17 inches at Clear Lake, 19 inches at Watertown, and 20 inches at Bryant.
Some automobiles went into the ditch, and many other vehicles were damaged in accidents. Many stranded motorists had to abandon their cars in the hardest hit areas. Travel was not advised across the entire region. A school bus slid into a ditch east of Castlewood with no injuries. Interstate-29 was closed from 3 pm the 25th until 3 pm on the 26th from Brookings north to the North Dakota border. Also, South Dakota State Highway 12 was closed from Webster to the Minnesota line from the afternoon of the 25th until the late morning of the 26th. Most counties affected by the storm opened emergency shelters when Interstate 29 was closed to house stranded motorists. Also, many schools were closed across the area.
The very heavy snow set several records across the area. The 19 inches at Watertown broke its all-time 24-hour snowfall record of 16 inches. Both Victor and Clear Lake had their second-highest snowfall ever recorded in a 24-hour period. Watertown and several other locations in northeast South Dakota received near-record or record snowfall for April. Watertown's 29.5 inches of snow for April was almost their average seasonal snowfall.
