DISCUSSION...Regenerative thunderstorm development persists in parts of central TX across the outflow from an MCS that decayed this morning. Surface temperatures continue to warm into the upper 70s to low 80s within cloud breaks south and east of the large-scale outflow boundary arcing across east TX. This is yielding moderate buoyancy amid upper 60s to low 70s surface dew points. With a favorable deep-layer wind profile (0-6km shear near 50 kts) per GRK VWP data, a couple supercells within an emerging cluster may develop. Overall convective mode will likely remain nebulous for the next few hours with uncertainty on whether a supercell can become sustained and track along the remnant outflow boundary. Should this occur, it would support a late afternoon tornado threat while the region remains on the southwest periphery of 850-mb winds in excess of 30 kts. ..Grams/Hart.. 04/28/2024 ...Please see www.spc.noaa.gov for graphic product...
