Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1135 PM CST Sun Jan 23 2022 Valid 241200Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated weak thunderstorms are possible from southeast Texas into western Louisiana beginning late on Monday. ...TX/LA... Water-vapor imagery depicts the center of an upper low just south of the NM border over northern Mexico, shifting east toward TX in line with latest model guidance. This low will open up and deamplify as it approaches the lower MS Valley late in the period. In response to this feature, a weak surface wave has formed off the south TX coast and a low should evolve and track across the northwestern Gulf Basin, likely remaining south of the LA coast Monday night. As a result, low-level warm advection in advance of the short wave will contribute to elevated convection north of the boundary across southeast TX into western LA. Some of this activity is expected to generate lightning. Forecast soundings are not particularly buoyant with the most unstable parcels being lifted well above 850mb much of the period. ..Darrow/Wendt.. 01/24/2022
