strong wind shear over Texas. Later that day, a low-level low-pressure area developed west of Wichita Falls at the intersection of a dry line extended southward across Central Texas and the stationary front extended eastward across the Red River valley. With the low-pressure system now in place, the air mass over the Red River valley became increasingly unstable, featuring surface temperatures near 90 °F (32 °C) and high dew points caused by the northerly surge of moisture induced by the subtropical jet. The combination of high temperatures and a moist atmosphere resulted in a favorable environment for thunderstorm development. However, despite the heat, temperatures alone were insufficient in breaking the capping inversion–an area of warmer air aloft that prevents the relativity cooler air near the surface from rising. Instead, the approaching shortwave trough provided the impetus necessary to force convection to occur, allowing for the formation of showers and thunderstorms. Initially, computer models indicated that the day's storms would primarily feature strong winds and hail with a minimal risk for tornadoes, with severe weather occurring mainly north of the stalled front in Oklahoma. However, conditions improved further than expected, leading the National Weather Service Weather Forecast Office in Fort Worth, Texas to intensify its verbiage in its public forecasting products as the day progressed and highlighting areas around the Dallas–Fort Worth metroplex as potential risk areas for tornadoes. Thunderstorms began to develop earnestly along the dry line as the afternoon progressed, beginning with initial storm development northeast of Abilene. The strong southwesterly winds aloft from the curved subtropical jet over the region helped to ventilate the storms, allowing for their persistence and intensity. The SPC issued its first of two tornado watches for the event at 2:53 p.m. CST (20:53 UTC) for portions of southern Oklahoma and North-Central Texas. The most favorable environment for tornadoes was initially over the Red River but shifted southward to include the Dallas–Fort Worth area in the evening hours. As storms continued to develop along a line paralleling Interstate 35, some storms congealed into a mesoscale convective system near the Metroplex; this cluster of storms produced both F3 tornadoes in Fort Worth and Arlington. The complex of storms eventually evolved into a transient bow echo that continued to track eastward into Louisiana. Elsewhere, supercells continued to propagate eastward across North and South-Central Texas along the dry line, slowly weakening after sunset. Confirmed tornadoes March 28
