072 ACUS01 KWNS 281930 SWODY1 SPC AC 281929 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0129 PM CST Fri Nov 28 2025 Valid 282000Z - 291200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe thunderstorms are anticipated today/tonight. ...20z Update... No changes are needed to the D1 Convective Outlook. See previous discussion below for more info. ..Thornton.. 11/28/2025 .PREV DISCUSSION... /ISSUED 1011 AM CST Fri Nov 28 2025/ ...Southern Plains vicinity... A midlevel shortwave impulse will eject across the southern Rockies into the southern Plains today ahead of a stronger upper trough digging southeast from the northern Rockies into much of the Great Plains tonight. Resulting increases in west/southwesterly midlevel flow will overspread weak northward moisture return across TX as a surface low develops/modestly deepens over KS/OK. Showers will increase today into tonight from central TX, north and east across portions of the Plains into the Ozarks. Isolated thunderstorms will be possible this evening and tonight as midlevel temperatures cool and lapse rates modestly steepen. However, meager boundary layer moisture will limit instability, with forecast soundings generally indicating 500 J/kg or less MUCAPE. Severe potential appears low given expected modest updrafts intensity/longevity. $$
