Daily Historical Weather for April 29
On April 29, 1985, a tornado damaged parts of Ardmore, injuring one person. This tornado is unique in that it was the first tornado to be probed by a ground-based instrument package. A crew from the National Severe Storms Laboratory dropped the instrument package, appropriately called TOTO, for Totable Tornado Observatory, into the path of the storm to get accurate readings of conditions inside the tornado.
While April does produce quite a few rainy days in Oklahoma City, it is not known for extremely heavy rainfall. The exception to this rule occurred back in 1947, when almost one foot of rain fell during the month. The 11.91 inch monthly total at Oklahoma City made April of 1947 the wettest April of record, but only the 8th heaviest monthly rainfall since accurate records began in 1891.
