The May 19, 2010 Tornadoes in Western and Central Oklahoma

The May 19, 2010 Tornadoes
in Western and Central Oklahoma

A large storm system moved through the southern and central Plains during the morning and afternoon of the 19th. Thunderstorms, some of them severe, had developed over the Texas panhandle and moved east into northwest and north central Oklahoma during the early morning hours. Additional development, aided by the low-level jet, occurred into parts of central Oklahoma, north of a warm front that was slowly moving north to near Interstate 40. Rainfall amounts with the morning thunderstorms ranged from 0.75 to 1.50 inches. The precipitation finally ended by late morning, with the warm front continuing to slowly lift north.

By mid afternoon, the well-defined front was located from parts of west-central into central Oklahoma, just north of the Oklahoma City metro areas. Afternoon heating along and south of the boundary allowed for temperatures to rise into the upper 70s and lower 80s. Dew point temperatures also rose into the middle and upper 60s. The atmosphere was primed for thunderstorm development with up to 3000 J/kg of CAPE present and little convective inhibition remaining. Strong wind shear was in place, more than sufficient for rotating thunderstorms, and the presence of the warm front only added to the strong turning of the winds in the lower levels. A PDS Tornado Watch was issued by the Storm Prediction Center for a large part of central and western Oklahoma, as visible satellite imagery showed rapidly developing towering cumulus clouds near the warm front.

Two main thunderstorms developed near and along the front, one over Roger Mills and Dewey counties, and the other over northern Blaine county. The storms quickly took on tornadic characteristics, with the first tornado of the day occurring north of Leedey in Dewey county. Another tornado, and probably the most photographed and videoed tornado of the day, occurred just north of Hennessey. Tornadoes and large hail continued to be reported across western and central Kingfisher county, and across northern Logan, southeast Garfield, and Payne counties (see graphic below). Another thunderstorm developed further east along the dry line later in the afternoon, and the storm eventually produced a tornado west of Prague in Lincoln county. Finally, two other supercell thunderstorms developed further south along the dry line that moved into central Oklahoma. Although both showed significant rotation on radar, only the supercell that moved from Stephens through Murray counties produced tornadoes. Two tornadoes were reported, one just southeast of Wynnewood and another north of Sulphur.

Additional severe thunderstorms developed across southern Oklahoma, but the main impacts had shifted from tornadoes to large hail and very heavy rainfall. By the time it was all said and done, five main supercells had occurred over parts of western and central Oklahoma, producing at least nine tornadoes. Thankfully, widespread significant damage did not occur due to the location/short duration of the tornadoes, and only three minor injuries were reported.
