NWS Preliminary Investigation Shows Six Tornadoes, Monday

BEATRICE – National Weather Service officials have confirmed six weak, short-duration tornadoes in Monday’s severe weather.  All were rated EF-Zero…the weakest rating on the scale used to rate twisters.

One touched down near Louisville in Cass County, with peak wind speeds of only 60 miles per hour.  A second twister came down between Louisville and Murray and had peak wind speeds of about 75 miles per hour.

A brief twister did damage to trees between Louisville and Murray.  It had estimated top winds of 70 miles per hour.

A fourth tornado west of Thurman, Iowa in Fremont County had wind speeds of up to 82 miles per hour, which weather experts said was a small tornado embedded in an area of strong, straight-line winds.  It tore up and twisted tree tops.

A fifth tornado happened near Elk Creek in Johnson County.  It had top wind speeds of 72 miles per hour.

The sixth tornado near Steinauer and Table Rock had wind speeds of up to 74 miles per hour.

National Weather Service officials said the tornadoes ranged in width from ten to forty yards and were on the ground likely no more than a tenth of a mile.

During the late afternoon and evening of June 11, 2018, the thunderstorms developed along a cold front moving through eastern Nebraska and a warm front that trailed southeast into western Iowa.  National Weather Service officials say the storms produced up to baseball-sized hail and damaging straight-line winds.
