SPC Feb 25, 2022 2000 UTC Day 1 Convective Outlook

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0124 PM CST Fri Feb 25 2022 Valid 252000Z - 261200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the continental United States through tonight. ...Discussion... No change. ..Smith.. 02/25/2022 .PREV DISCUSSION... /ISSUED 0957 AM CST Fri Feb 25 2022/ ...Synopsis... A surface cold front will continue to move slowly southeastward across AL/GA/Carolinas, in the wake of a midlevel trough moving across the Mid Atlantic/New England today. Weak elevated convection and isolated lightning strikes have been observed this morning from the southern Appalachians into AL, though the trend has been for this convection to slowly diminish since 15z. Given only marginal buoyancy rooted in the 850-700 mb layer (per the 12z BMX sounding) and weakening forcing for ascent through the day, the prospects for additional thunderstorms beyond 1630z from AL/GA into the Carolinas appear too limited to warrant the addition of an outlook area.
