This tornado crossed into Kentucky from Stewart County, Tennessee. Several barns and grain bins were damaged or destroyed. A dairy barn with 45 cows inside was destroyed. Although all the cows were trapped under the collapsed barn, only two of the cows were injured. One of the cows was thrown 500 feet from its stall. Numerous large trees were snapped or uprooted. A tractor-trailer rig hauling freight was overturned at mile-marker 85 on Interstate 24. The driver suffered minor injuries and was taken to a regional hospital. The roof was torn from an agricultural chemical storage building. A tool barn was destroyed. At a farm near Pembroke, a large tree fell on a house, a large barn was flattened, and two large grain bins were destroyed. Peak winds were estimated near 120 mph, but the majority of the damage path was EF-1. The average path width was 150 yards.
During the afternoon on the 23rd, a broken line of convection formed in southeast Ohio ahead of a slow moving cold front.  This convection eventually extended south into northeast Kentucky.  Dry air in the mid levels, as well as deep layer undirectional shear, lent toward a damaging wind threat as opposed to large hail.
After the initial line passed well into West Virginia, recovering surface temperatures and enough shear was present to support further development during the early evening.

A deepening low pressure system off the Northwest Coast resulted in a strengthening southwest to northeast surface pressure gradient across northeastern Washington during the early morning hours.  Subsequently, winds began to pick up out of the northeast in the neighborhood of up to 15-20 mph sustained and gusting up to around 30 mph.  Although these winds were not abnormally strong, their northeasterly direction were favorable for developing relatively high swells of up to one and a half feet along the western shore of Deer Lake in southeastern Stevens County.

Temperatures near or just above 100 degrees, frequent gusty winds, moderate to low relative humidity quickly erased any short term drought relief provided by mid May rainfall as conditions deteriorated from Severe to Extreme across all of Brooks County for the balance of June.

Property damage: 0.00K
Reported by: Other Federal Agency

Severe (D2) Drought conditions deteriorated to Extreme (D3) in all of Brooks County on June 7th, and would continue through the end of the month.  Rainfall of more than 2 inches across the southern half of the county would provide a bit of relief at month's end.  Livestock, particularly cattle head, were affected most as very short moisture levels dwindled available feed and required [a large sale] of cattle much earlier in the year than usual.  [Hay supplies were limited/damaged by the extreme drought - details here].
Severe thunderstorms developed in the morning, and again in the
afternoon, on Tuesday, 21 June 2011.  The thunderstorms formed after
several days of record setting hot weather, which was the result of  a
persistent ridge of high pressure in the middle and upper atmosphere.
On 21 June 2011 a strong trough developed in the middle and upper levels
of the atmosphere moved from west to east across the central Plains
breaking down the upper level ridge over the Four State area.  This
strong upper level trough allowed for gusty south winds to occur at the
surface of the atmosphere in the four State area, and brought enough
lift and instability to the atmosphere to allow scattered severe
thunderstorms to develop both in the morning and the afternoon of 21
June 2011.  These thunderstorms produced wind damage and a few
tornadoes, in addition to brief episodes of heavy rainfall.
