SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1213 AM CDT Tue Oct 07 2025 Valid 081200Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Wednesday. ...Synopsis... An amplified upper ridge will remain centered on the Plains on Wednesday. Meanwhile, an upper trough over the Northeast and Mid-Atlantic will continue to lift northeast, moving offshore the Atlantic coast by the end of the period. A surface cold front will be oriented from coastal New England toward the southern Appalachians and the central Gulf Coast Wednesday morning. As the front continues to develop offshore into the Atlantic and Gulf, strong high pressure will build over the Great Lakes/Midwest. Easterly low-level flow will transport modest moisture westward across the Rio Grade and into portions of NM/AZ on the western periphery of the strengthening surface high. Isolated thunderstorms will be possible across portions of AZ/NM where modest boundary layer moisture beneath midlevel lapse rates near 7 C/km supports weak destabilization. Vertical shear will be weak, and convection will be relatively shallow, given high bases and low tops. While some locally gusty winds could occur, severe potential is low. Additional thunderstorms are possible across parts of the Southeast into the southern Mid-Atlantic ahead of the front. Instability will be limited by poor lapse rates and cloud cover. Vertical shear will also weaken through the day as the upper trough continues to lift further from these regions. Severe thunderstorms are not expected. ..Leitman.. 10/07/2025
