On April 5, 1947 a squall line of severe storms passed the viewing area with t'storm wind gusts estimated as high as 75 mph.

However, behind the line, a gradient wind event brought winds of up to 60 mph as a very strong storm system pivoted through Iowa to Wisconsin.

As you can see in the graphic below, the squall line was approaching at 1:30 p.m. on April 5 with surface low pressure down to an impressive 984 mb in Iowa.

In Indiana, the highest t'storm gusts & worst wind damage was reportedly in southwestern Indiana.  It is likely that surface CAPE was higher there, leading to greater severe gusts.

You can see in this article below regarding the passing of Henry Ford that there was still no power on the night of April 7-8 in southeastern Michigan:

Just four days later, a historic, massive EF5 tornado struck Oklahoma (usually called the "Woodward Tornado"):

1947 was a historic weather year for the country as a whole.

An ice storm hit the viewing area in early January with widespread tree & powerline damage.  Extensive damage occurred at Fort Campbell from apparent tornado & damaging winds from this weather system.

In late January, a major blizzard completely shut down Milwaukee.  This storm brought severe weather outbreak to parts of central & southern Indiana with multiple tornadoes.  One struck the Greenwood Aiport, destroyed & rolling aircraft.  Multiple other tornadoes occurred in Missouri & Arkansas.

A major blizzard brought New York City its heaviest snowstorm on record in January.

A widespread, damaging non-t'storm high wind event on March 24 brought 50-70 mph gusts to the area (caused by very deep surface low).  Trees, powerlines were downed & homes suffered roof damage.  Wind event also swept Kentucky to Ohio, West Virginia to Pennsylvania, Maryland, Virginia with widespread damage.  Winds in higher terrain gusted to 90 mph.  Gusts of 60-80 mph common elsewhere.  Johnstown, Pennsylvania gusted to 73 mph.

An extremely rare end of May winter storm brought snowfall from Nebraska & Iowa to Wisconsin

We went from record cold in July to record heat in August with drought conditions.

On a +100-degree day, a t'storm developed & produced a gust of 78 mph at the Purdue Airport.  Multiple nearby hangars were damaged.

Historic tornado outbreak hit Oklahoma in early April, including the great Woodward EF5.

This list goes on & on!
