Moist southerly winds brought 50 to mid 60 degree dew points into the area. Due to so much moisture present, low status formed and lasted through the early afternoon. The stratus caused the atmosphere to remain stable through the early afternoon until the stratus began to clear out. With the moisture still present during the afternoon and a strong jet stream overhead, thunderstorms that former over the higher terrain of Southeast Wyoming began to move eastward into the panhandle.  The unstable conditions also allowed thunderstorms to develop in the panhandle during the late afternoon and evening hours.

Tornado in SCOTTS BLUFF, NEBRASKA
From 07-JUN-10 18:23:00 to 07-JUN-10 19:00:00 (MST-7)
Location: SCOTTSBLUFF
Tornado F-scale: EF1
Reported by: NWS Storm Survey

A storm damage survey team from the National Weather Service in Cheyenne confirmed an EF-1 tornado touched down in eastern Scotts Bluff County on Monday evening June 7th, 2010.  Additionally, some of the damage was attributed to strong straight-line thunderstorm winds.  Baseball sized hail accompanied this tornadic thunderstorm.

Based on the survey and interviews with area residents, an EF-1 tornado touched down on the east side of the city of Scottsbluff. An automotive dealership sustained roof damage. Five mobile home trailers were over-turned in the Wagon Wheel Trailer Park. An outbuilding collapsed and a metal shed sustained substantial roof damage 2.4 miles southeast of Scottsbluff along County Road 24. A roof was torn off a garage and numerous trees were uprooted south of Highway 26, 5.4 miles southeast of Scottsbluff. Four grain bins were removed from their foundations in the town of Melbeta. One of the grain bins was lifted one half mile from its foundation. Based on this damage it was determined that the tornado path consisted of numerous spin-ups over the 19-mile damage path. The tornado finally dissipated just north of Chimney Rock at around 8 pm.
The damage to the mobile homes...trees north of Melbeta...and the grain bins were consistent with EF-1 tornado damage with winds estimated to be in the 93 to 98 mph range.
