ACUS03 KWNS 221921 SWODY3 SPC AC 221920 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0220 PM CDT Sun Mar 22 2026 Valid 241200Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms will be possible on Tuesday from far southeast Georgia to the Florida Peninsula. No severe threat is forecast. ...Synopsis... A mid/upper shortwave trough and strong surface low are forecast to move across parts of British Columbia on Tuesday, as a trailing cold front moves across the Pacific Northwest. Weak convection may develop along and in the wake of this cold front, but inland buoyancy appears too meager for more than very isolated thunderstorm potential. Farther south and east, an upper ridge is forecast to amplify somewhat over the Southwest on Tuesday, with a west-northwesterly flow regime expected to persist downstream across much of the central/eastern CONUS. An embedded mid/upper-level shortwave trough will move across the lower MS Valley and Southeast. A cold front that moves into north FL late D2/Monday is forecast to slow down and weaken on Tuesday. Modest buoyancy may develop near the remnant front, and isolated storm development will be possible across the FL Peninsula and adjacent southeast GA, both diurnally, and potentially in response to the approaching shortwave trough late in the period. Weak deep-layer shear is expected to limit storm organization. Some weak destabilization will also be possible near the remnant front across the central Gulf Coast and lower MS Valley. It appears the shortwave trough will be displaced north of any appreciable destabilization along the western portion of the remnant front, but weak convection cannot be ruled out from LA/MS to the FL Panhandle. ..Dean.. 03/22/2026 $$
