This may include the evolution of an intensifying supercell or two, which could pose potential for producing large, damaging hail impacting at least parts of the Metroplex by 5-7 PM. If/when this becomes more certain, a severe weather watch probably will be needed. DISCUSSION...Just ahead of a southward advancing cold front, now southeast of the Wichita Falls TX vicinity, stronger surface heating and deeper boundary-layer mixing are ongoing in a narrow corridor roughly focused along I-20 across the Abilene into Fort Worth vicinity. At least attempts at deepening convective development are underway within this regime to the west-north of Mineral Wells, where low-level forcing for ascent may be aided by weak low-level warm advection and locally enhanced convergence, near the general intersection of the cold front and dryline. This is occurring beneath larger-scale mid/upper ridging overspreading much of the southern Great Plains. However, based on various model output, including convection allowing guidance, further insolation, coupled with subtle mid-level height falls and cooling, might become supportive of thunderstorm initiation within the next few hours. How long this activity is sustained before tending to be undercut by the southward advancing cold front, and whether this occurs prior to acquiring inflow of higher boundary-layer moisture content along and to the east of the dryline, remain unclear. Even in the drier more strongly heated boundary-layer just to the west/southwest of the cold front/dryline intersection, initial thunderstorm development may become capable of producing large hail and a locally strong downburst, in the presence of steep-lapse rates and strong deep-layer shear. If convection is able to acquire inflow of boundary-layer air with dew points near 70F, which may be maintained across eastern portions of the Metroplex, the potential for much larger and damaging hail will become considerably greater. ..Kerr/Smith.. 05/05/2026 ...Please see www.spc.noaa.gov for graphic product...
