521 ACUS01 KWNS 230037 SWODY1 SPC AC 230035 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0735 PM CDT Sun Sep 22 2024 Valid 230100Z - 231200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHWEST TEXAS... ...SUMMARY... A few strong, to marginally severe, thunderstorms remain possible this evening across southwest Texas. ...01z Update... Upper low is gradually deamplifying as it becomes positive tilted over the central/southern High Plains region. This evolution has contributed to a surging cold front that now extends from the Ozarks-southeast OK-Edwards Plateau of southwest TX. The majority of convection remains along the cool side of the boundary, but a few storms are noted near/south of the wind shift. Surface temperatures remain in the upper 80s to near 90F across southwest TX, but mid-level lapse rates are modest at best, and this is likely hampering updraft strength within an otherwise strongly sheared environment. Additionally, very few severe wind gusts have been reported with this activity, and hail will likely struggle to achieve levels above 1 inch, except near the International border near Sanderson. Overall, severe threat appears fairly low this evening, but a few gusts and marginally severe hail remain possible. ..Darrow.. 09/23/2024 $$
