ACUS01 KWNS 091259 SWODY1 SPC AC 091258 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0658 AM CST Thu Jan 09 2025 Valid 091300Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast through tonight. ...Discussion... A low-latitude positive-tilt upper trough over the Four Corners and northwest Mexico will slowly transition eastward toward the southern High Plains through tonight. A related strengthening of deep-layer southwesterly winds will occur across the southern Plains, atop a cool and stable air mass at the surface. Warm advection and elevated moisture transport will be maximized across broad parts of central/southern to east Texas today, and into the Lower Mississippi Valley tonight. Weak elevated buoyancy will support occasional thunderstorms. It is unlikely that instability will be strong enough for any hail risk given poor lapse rates aloft. ..Guyer/Bentley.. 01/09/2025 $$
