March 4

TodayinWeatherHistoryFrom NWS
1985
: Rain and freezing rain fell across Iowa on March 3-4 with some southeastern stations reporting daily record precipitation amounts including 2.38 inches at Donnellson, 3.38 inches at Fort Madison, and 4.68 inches at Keokuk where the 7.38 inches received during the month made it their wettest March on record. Glazing was also reported across northern Iowa. As the rain began to taper off strong winds blew in from the northwest, averaging 25 to 30 mph on the 4th with gusts in excess of 50 mph damaging trees in some areas.

This Day in National/World Weather History …
 4 March 1841 → President William Henry Harrison delivered a 100-minute inaugural address in freezing temperatures, while refusing to wear a coat or hat. He came down with pneumonia and died on April 4, only 32 days into his presidency.
 4 March 1899 → The world’s highest recorded storm surge occurred at Bathurst Bay, Queensland, Australia when Tropical Cyclone Mahina created a surge 42 feet deep. The storm also caused the largest death toll of any natural disaster in Australian history, with 400 casualties.
 4 March 1909 → The Inauguration ceremony of President William H. Taft was forced indoors due to a blizzard that dropped 10 inches of snow on the Capital. Strong winds toppled trees and telephone poles. All activity was brought to a standstill. It took 6,000 men and 500 wagons to clear 58,000 tons of snow and slush from the parade route. Just after the swearing-in, the snow tapered off.
