Meteorological events that happened on March 17th:
A late-winter thunderstorm struck with thunder that boomed like cannon fire at Halifax, Nova Scotia Canada. A lightning bolt entered a home, hurling a young woman sitting at the family piano across the room.
A winter storm in southwestern and central Tennessee produced 26.3 inches of snow at Riddleton, and 18.5 inches at Memphis. It was the deepest snow on record for those areas.
The temperature at Snake River, WY dipped to -50° setting a record for the U.S. for the month of March.
Suffocating dust storms occurred frequently in southeast Colorado between the 12th and the 25th of the month. Six people died, and many livestock starved or suffocated. Up to six feet of dust covered the ground. Schools were closed, and many rural homes were deserted by tenants.
An early season heat wave occurred across the East. Some records included: Raleigh, NC: 92°, Richmond, VA: 91°, Sussex, NJ: 90°, Hammonton, NJ: 90°, Norfolk, VA: 89°, Washington, D.C.: 88°, Salisbury, MD: 87°, Philadelphia, PA: 86°, Trenton, NJ: 86°, Baltimore, MD: 85°, Reading, PA: 85°, Allentown, PA: 84°, Wilmington, DE: 83°, Atlantic City, NJ: 83° and Mt.

The ban on using the word "tornado" issued in 1886 ended on this date. In the 1880s,
John P. Finley of the U.S. Army Signal Corps, then handling weather forecasting for the
U.S., developed generalized forecasts on days tornadoes were most likely. But in 1886,
the Army ended Finley's program and banned the word "tornado" from forecasts because the harm done by a tornado prediction would eventually be greater than that which results from the tornado itself?. The thinking was that people would be trampled in the panic if they heard a tornado was possible. The ban stayed in place after the Weather Bureau, now the National Weather Service, took over forecasting from the Army. A tornado that wrecked 52 large aircraft at Tinker Air Force Base, OK, on 3/20/1948, spurred Air Force meteorologists to begin working on ways to forecast tornadoes. The Weather Bureau also began looking for ways to improve tornado forecasting and established the Severe Local Storm Warning Center, which is now the Storm Prediction Center in Norman, OK. The ban on the word "tornado" fell on this date when the new center issued its first “Tornado Watch”.
