As we prepare to celebrate Independence Day in Minnesota this year there is a threat of showers and thunderstorms so some of our outdoor plans must remain tentative. Historically Minnesota citizens have coped with a variety of extreme weather on July 4th:
Some of the more noteworthy July 4th weather episodes have included:
Extreme heat: 107 F at Pipestone and Worthington in 1936; 105 F at Wheaton in 1949 with Heat Index values that ranged from 110 to 115 F; 105 F at Redwood Falls in 1966; and 106 degrees F at Browns Valley in 1988.
Extreme cold: morning low of 30 F at Alborn in 1932; morning low of 28 F at Grand Marais in 1950; and morning low of 27 F at Tower in 1972. Daytime high of only 58 F in the Twin Cities in 1967 as people wore jackets to watch the fireworks.
Extreme rainfall: 3.25 inches at Montevideo in 1900; 3.51 inches at Worthington in 1978; 9.78 inches at Milan in 1995; and 7.81 inches at Hibbing in 1999 (overnight into the 5th). For most of Minnesota rain occurs about 40 percent of the time on July 4th.
Extreme wind: The famous "derecho" wind storm of 1999 brought 80-100 mph winds to the Fargo-Moorhead area, then later in the day to the Boundary Waters Canoe Area where tens of millions of trees were blown down.
Please pay attention to the weather this weekend as well and be safe.(1 Comments)
