Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0232 PM CDT Sun Apr 06 2025 Valid 062000Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHEAST... ...SUMMARY... Scattered damaging winds and isolated tornadoes remain possible through this evening across parts of the Southeast. Marginally severe wind gusts will also be possible northeastward into parts of the southern Appalachians and southern Virginia. ...20Z Update... The only appreciable change with this update was to trim severe probabilities behind multiple ongoing convective clusters across the Southeast. Damaging winds and a few tornadoes will remain the primary severe concerns with this activity through about mid evening, after which thunderstorms should tend to weaken. ..Gleason.. 04/06/2025 .PREV DISCUSSION... /ISSUED 1126 AM CDT Sun Apr 06 2025/ ...Southeast... A composite squall line with some embedded bows, along with some preceding thunderstorms and occasional transient/mostly weak supercells thus far, extends from the Alabama/Georgia border vicinity (west/southwest of Atlanta metro) southwestward into east-central Alabama and southwest Alabama near Mobile as of 1130am CDT/1230pm EDT. Multi-layer cloud cover extends across the nearby warm sector to its east, but a moist environment (upper 60s/near 70F) and some additional heating will lead to further destabilization, a change that should most appreciably occur northeastward into western/north-central Georgia owing to differential heating and essentially a northeastward-advancing warm front. The strongest forcing for ascent and deep-layer winds will lag (to the west-northeast) the composite convective line, but sufficient vertical shear extends into the warm sector to support organized storm modes including semi-discrete supercells and line-embedded bows. Damaging wind and tornado risks will exist through at least early/mid-evening. ...Southern Appalachians/Piedmont... Warmer air aloft is expected to have a greater influence over these regions. With less buoyancy anticipated through the afternoon, convective intensity should remain muted. Given the strong shear across these areas, a few strong to severe storms may produce isolated wind damage.
