412 ACUS01 KWNS 200055 SWODY1 SPC AC 200053 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0753 PM CDT Wed Jun 19 2024 Valid 200100Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTH TEXAS... ...SUMMARY... A few tornadoes are possible across south Texas tonight in association with Tropical Storm Alberto. Otherwise, scattered strong to locally severe thunderstorms remain possible over the New Mexico region. ...01z Update... Tropical Storm Alberto is propagating slowly west toward the Mexican Coast, and the center of circulation is forecast to track inland later tonight about 22N, or around 250 miles south of Brownsville TX. Widespread convection is rotating inland across coastal South TX, and low-level shear is forecast to increase through the evening hours. 00z sounding from BRO exhibited surface-3km SRH around 230 m2/s2, and this should strengthen as 850mb flow intensifies along the north side of the cyclone. Tornado threat should gradually increase with inland-moving supercells. Farther northwest, scattered strong/severe slow-moving thunderstorms are propagating north across south-central NM. Another small cluster of storms is drifting northeast off the higher terrain to the east of ABQ. Gusty winds and some hail threat linger with this activity until the boundary layer cools later this evening. ..Darrow.. 06/20/2024 $$
