EF1 tornado in Pontotoc County, Oklahoma

For the second time this spring, a tornado struck the city of Ada. This tornado began on the north side of Ada, near the intersection of North Broadway Avenue and NW JA Richardson Loop. Several homes suffered roof damage along Cottage street as the tornado moved east and northeast. EF1 damage was noted at a hotel along the Loop, where damage to roofs and awnings were observed and one person was injured. The tornado moved across the North Hills Shopping Center, damaging several businesses before moving to the northeast and dissipating northeast of Ada.

A severe weather and flash flood episode occurred across central and southern portions of the WFO Norman Forecast Area from the evening of the 19th into the early morning hours of the 20th. A slow-moving upper system continued to approach the area on the 19th. This, along with strong/moist low-level ascent atop a quasi-stationary boundary, helped initiate widespread thunderstorms across the region mentioned above. Strong wind shear and instability, especially along and ahead of the surface boundary, promoted organized thunderstorms, producing hail, wind and tornadoes. A few strong tornadoes also occurred (near Courtney in Love County and Little City in Marshall County). This episode also observed the first fatal weak (F/EF0-1) tornado since 1988 across the WFO Norman Forecast Area. Flash flooding also became a concern by the late evening of the 19th, with two flood-related fatalities occurring in the city of Moore, as multiple vehicles were swept off of Eastern Avenue into a nearby creek.
