EF1 tornado in McClain County, Oklahoma

This tornado touched down in the northern part of Blanchard and moved north-northeast. The tornado initially was EF0 producing some tree limb damage and damage to one house near Northeast 40th Street and Rockwall. After crossing the Norman Spur of the Bailey Turnpike and moving into Newcastle, EF1 damage was noted to trees and homes as it moved through neighborhoods in Newcastle north of SW 24th Avenue. Newcastle Elementary School received significant roof damage as the tornado continued to move north just west of U.S. Highway 62. The tornado finally dissipated in north Newcastle to the northwest of US-62 and Northwest 16th Street.

An expansive (high-amplitude) longwave trough, in combination with unseasonable moisture/instability and wind shear, yielded a prolonged period of severe weather and flooding across the southern two-thirds of Oklahoma and portions of western-north Texas. While thunderstorms began during the daytime on the 2nd, the episode's first (and most impactful) convective period occurred during the late evening hours of the 2nd into early morning of the 3rd. Both linear and cellular convective modes were observed during this time, producing numerous reports of damaging winds and a localized tornado event along the Interstate 44 corridor. This included three EF-3 tornadoes, causing significant damage across the eastern/southeastern suburbs of the Oklahoma City Metropolitan area and in areas east of Duncan/Comanche in Stephens County.

Another widespread round of strong to severe thunderstorm activity occurred from the early afternoon into mid-evening on the 3rd, primarily across south-central into southeast Oklahoma. Once again, a mixed-mode event produced numerous reports of severe weather (mainly wind and a few tornadoes).
