  05/25/1955 2100 13 440 F3 0 1 Grant Deer Creek

At 9:00 pm CST, a tornado caused $5,000 in damages to crops and $25,000 in damages to other properties in the Deer Creek area in Grant County. One person was injured by the storm. This tornado was part of a severe weather outbreak that produced nearly 20 tornadoes in Oklahoma including the F5 tornado that hit Blackwell.

  04/02/1956 1945 18 100 F2 0 4 Garfield/ Grant NW Garfield county - just SW of Medford

A tornado touched down about 2.5 miles west of Kremlin in northwest Garfield County around 7:45 pm CST and moved to the northeast into Grant County about one mile west of Pond Creek and then through Jefferson before dissipating about 1 mile west of Medford. The tornado injured 4 people along its path at one home in Grant County. The total property damage was $100,000.

  03/16/1965 1640 83 300 F4 0 7 Grant OK/ Kay OK/ Sumner KS/ Cowley KS 6 SSW Nash OK- 2 N Jefferson OK- 4 N Braman OK- Geuda Springs KS- 6 E Winfield KS [Two injuries in Oklahoma]

Although this event is listed a single tornado with an 83-mile track, it is most likely that a series of at least 4 tornadoes touched down in Oklahoma and Kansas, with at least one violent tornado occurring within this tornado family in Oklahoma.

Two funnels were first reported before a tornado formed 5.7 miles south-southwest of Nash at 4:40 pm CST where the Liberty Church and adjacent parsonage were leveled along with a steel granary. The storm moved northeastward and quickly dissipated east of Nash at 4:55 pm CST. This tornado was probably the first in a series of tornadoes produced by the same supercell thunderstorm. Observers noted a fast movement of the thunderstorm along with numerous tornado touch-downs.

A tornado, probably the second in the series, was observed moving to the northeast 2 miles north of Jefferson. It then caused heavy damage along a 6-mile path from U.S. Highway 81, 3 miles southwest of Medford to U.S. Highway 64, 4 miles east of Medford. Five farmsteads were heavily damaged here and 1 woman was injured.

The greatest damage and longest track occurred when what was probably the third tornado in the series initiated 5 miles northwest of Deer Creek in Grant County, and then moved northeastward to the Grant-Kay County line 5 miles south of the Kansas border. One man was injured 6 miles northeast of Deer Creek when he was caught inside his house, which was leveled. Fifteen farmsteads were hit, 6 of which were completely destroyed, and 3 received major damage.

Data from this event suggest that the tornado continued into the west corner of Kay County, destroying 10 summer cabins and trailer homes near Lake Blackwell and downing 70 power poles. The tornado was last sighted in Oklahoma about 1 mile south of the Kansas line and just east of Interstate 35 before it moved northeast into Kansas about 5 miles southeast of South Haven, KS. It was in a multi-vortex phase as it crossed the state border. From there the tornado moved rapidly to the northeast at 45 mph, hitting Geuda Springs, KS before dissipating 6 miles east of Winfield, KS.

Additional data from the event suggest that a fourth tornado also blew down signs along Interstate Highway 35, 3 miles south of Braman and then moved north-northeast, toppling a 262-foot microwave tower (rated to withstand 175 MPH winds) just north of Braman at 5:53 pm CST. A nearby compressor station also sustained major damage when one home and a 150-foot cooling tower were blown down. Damage was also reported 4 miles north of Braman.

  04/30/1973 2020 13 100 F2 0 6 Alfalfa/ Grant NE side of Great Salt Plains Reservoir - W of Medford

This tornado touched down on the northeast side of the Great Salt Plains Reservoir area, completely demolishing one mobile home and damaging 3 other trailers, a house, and a cafe. The tornado continued east-northeastward before lifting just west of Medford. The tornado was accompanied by straight-line winds which produced damage to many buildings over a half-mile-wide path within Medford.

  05/10/2010 1438-1534 41 1500 EF3 0 2 Grant OK/ Kay OK/ Sumner KS 8 SW Wakita OK- 5 SE South Haven KS

A significant outbreak of severe thunderstorms and tornadoes affected a large part of northern, central, and southern Oklahoma. Tornadoes were most numerous across central and southern Oklahoma, with significant damage occurring over many areas. Severe thunderstorms erupted by midafternoon across northern and western Oklahoma. Given the potent combination of ingredients in place, storms began to produce tornadoes quickly after initiation. Storm motions of 50 to 60 mph were common.

During the midafternoon hours, severe weather was confined to northern Oklahoma. It was there a long track supercell storm produced tornadoes near the Kansas border - including one rated EF3 - from near Wakita to north of Braman.

This tornado developed as a multiple-vortex tornado along State Highway 11 southwest of Wakita. The tornado initially moved east and southeast continuing to affect State Highway 11 before beginning an east-northeast movement across Grant County. The tornado was a large and occasionally multiple-vortex tornado as it moved northwest and north of Medford and was embedded within a larger scale circulation that was strong enough to produce damage along a wide area around the tornado path. The tornado caused significant structural damage about 5 miles northwest of Medford and 5 miles east of Renfrow, and many areas of tree and power pole damage.

The tornado crossed into Kay County from Grant County and continued to produce significant damage. One home was destroyed and another significantly damaged between the Grant County line and U.S. Highway 177. After the tornado crossed US-177, an anchored mobile home was destroyed and blown to the east, and a tri-level home was destroyed with the top floor blown about 50 yards northeast into some trees, and the ground floor pivoted and was displaced to the northwest exposing the basement where one minor injury occurred. The tornado continued to produce significant tree damage as it moved east-northeast, and blew semi-trucks over along Interstate 35 at the Kansas state line. This tornado crossed into Sumner County Kansas. See documentation from the NWS Wichita KS for additional information.

Two semi-tractor trailers were blown off of the Kansas Turnpike right at the Oklahoma/Kansas state line as the tornado crossed the interstate. The overturned semi's temporarily closed Interstate 35 for a short time as they blocked traffic in both directions. The tornado also caused significant tree damage as it moved northeast into rural Sumner County, Kansas.
