tornadoes – including the risk for strong (EF2+) tornadoes – and isolated instances of very large hail. On the morning of February 26, water vapor imagery depicted a well-defined and compact cold-core low progressing eastward across California and Nevada. A powerful shortwave trough accompanied this feature. Farther to the east, a warm front stretched from southern Louisiana across southern Texas, separating cooler and drier air to the north from a more unstable environment to the south. As low-level flow increased in advance of the cold-core low, southerly winds allowed that moist airmass to surge rapidly northward throughout the morning and afternoon hours. Much of the Texas and Oklahoma panhandles, as well as western Oklahoma, experienced a four to eight degree increase in dewpoints within just a three-hour period. Prior to the development of thunderstorms, strong wind fields already existed across the region, with bulk wind shear topping and forecast to increase further. As the evening approached, supercells developed in the Texas Panhandle, further organizing as a cold front overtook the preexisting dryline and contributed to greater focus for convective activity. To the north, a complex line of storms developed near a surface low in southwestern Kansas, where multiple tornadoes were reported. With time, the originally discrete storms from the Texas Panhandle became intertwined with a solidifying squall line pushing eastward into Oklahoma. These storms entered an environment of richer moisture, with dewpoints into the low 60s °F northward to near I-40, and modest instability on the order of 500-1,000 J/kg. Despite the presence of a capping inversion, strong forcing along the cold front was expected to erode inhibition, while low-level winds topping worked to assist in broad swaths of damaging winds. Favorable wind shear profiles supported embedded mesovortices and QLCS tornadoes within the line as the storm complex continued east. Multiple tornadoes occurred in the Eastern Texas Panhandle and Western Oklahoma, including a high-end EF2 tornado that obliterated a mobile home and killed one person near Cheyenne. Several damaging QLCS tornadoes qlso ended up touching down throughout the Oklahoma City metropolitan area, including another high-end EF2 tornado that caused significant damage in southeastern Norman. As storms entered eastern Oklahoma, they encountered a less favorable environment and weakened considerably, reducing the threat for severe weather with eastward extent into the pre-dawn hours of February 27, although scattered wind and tornado reports continued all the way into Missouri.
