SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CDT Mon Oct 27 2025 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are unlikely Wednesday. ...Synopsis... A deep upper low over the central US will continue to intensify before merging with a broader trough over the eastern US Wednesday and Wednesday night. A surface low over the Mid South will deepen and move toward the Atlantic Coast as a strong cold front continues to push offshore through the Gulf and Southeast. High pressure will develop within the post-frontal air mass supporting widespread offshore flow and drier conditions across much of the CONUS. The only exception will be across far south FL and the immediate Mid Atlantic coast where remaining southerly winds will support modest surface moisture for part of the day. However, the relatively shallow nature of the moisture and mid-level drying/subsidence southeast of the jet max will overspread the area ahead of the advancing front. This should limit thunderstorm potential before the cold front scours the remaining moisture offshore. Thus, thunderstorm chances currently appear to be below 10% over the CONUS. ..Lyons.. 10/27/2025
