Meteorological events that happened on March 20th:
This was the last of three consecutive record warms days across parts of Colorado. Denver broke a record soaring to 80°. This followed a record high minimum of 52°.
Heavy snow followed the passage of a front across the central Rockies. Denver reported 6.3 inches of snow with gusty winds. The strong cold front plunged temperatures from a high of 60° on 3/19 to a low of 1° on this date.
A late winter storm in Oklahoma produced nearly a foot of snow at Oklahoma City and at Tulsa.
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 F3 tornado tracked through Tinker Air Force Base in Oklahoma City, OK just before 10 p.m. destroying 54 aircraft, including 17 transport planes valued at $500,000 dollars a piece. Total damage amounted to more than $10 million dollars, a record for the state that stood until the massive tornado outbreak of 5/3/1999. Major Ernest W. Fawbush and Captain Robert C. Miller were ordered to see if operationally forecasting tornadoes was possible. The tornado prompted the first attempt at tornado forecasting. Forecasters at Tinker believed conditions were again favorable for tornadoes, and issued the first recorded tornado forecast. Five days later on 3/25 at 6pm, a forecasted tornado occurred, crossing the prepared base and damage was minimized. Their successful, albeit somewhat lucky, forecast paved the way for tornado forecasts to be issued by the U.S. Weather Bureau after a long ban.
The city of Juneau received 31 inches of snow in 24 hours, a record for the Alaska capital.
A coastal storm dumped heavy, wet snow in southeastern Pennsylvania and Maryland. 38 inches fell at Morgantown, WV in 24 hours with 50 inches in three days. Allentown, PA checked in with 20 inches.
National Airport only picked up 4.8 inches of wet snow. Arlington had a foot of snow.

A multi-vortex tornado raced through the suburbs of Welkom, South Africa destroying 4,000 homes.
A vigorous storm that started on March 17 and ended on this date across southern California produced 1 to 8 inches of rainfall in lower elevations and up to 14 inches of precipitation in the mountains. 2 to 5 feet of snow fell in the mountains.

Lightning struck at transformer in the North Park area of San Diego, knocking out power. Lightning also started a house fire. A waterspout came ashore to become a tornado at Camp Pendleton.

The first "shachenbao" or "sand-dust tempest" of the season severely reduced visibilities and covered everything around the city of Beijing, China in a fine layer of dust from the Mongolian Desert.
Killer tornadoes roared through southwestern Georgia during the early morning hours, killing six and injuring 200 others.
