EF1 tornado in Grant County, Arkansas

The tornado tore shingles and siding off a house, destroyed a shed, uprooted iron clothesline poles anchored in concrete, blew down an 80-foot tall amateur radio antenna, damaged the roof of a mobile home, took the roof off a shed, and blew down trees and power lines.

A large storm system in the Rockies headed through the Plains into the upper Midwest on the 29th. Rain increased ahead of the system, and became widespread in Arkansas. Meanwhile, a cold front arrived from the west. Because the system was so far to the north, it did not give the front much push. The front slowed down, which prolonged the rain. The result was widespread flash flooding, which gave way to areal flooding and river flooding. Winds changed direction and speed up through the atmosphere, a favorable condition for tornadoes. However, instability was sufficient only in southern Arkansas for the development of tornadoes.
