SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0125 PM CST Sat Nov 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Monday. ...Synopsis... A deep mid/upper-level trough will move eastward across the eastern CONUS Monday. A developing surface low initially off of the Mid Atlantic coast is forecast to deepen as it moves north-northeastward across eastern/northern New England through the evening. Modest MUCAPE near/east of the surface low track may support some potential for elevated convection with sporadic lightning flashes from the Cape Cod vicinity into central/eastern ME. Very cold midlevel temperatures will continue to support snow bands over and near the Great Lakes. Lightning potential over Lake Michigan may peak prior to the start of the period as the trough begins to shift eastward, but very isolated/sporadic lightning flashes may continue into Monday morning. A few lightning flashes also cannot be ruled out over Lake Erie and adjacent parts of OH/PA. Some instability may linger early in the period across far south FL and the Keys, but current guidance generally shows a limited signal for deep convection in this area prior to the frontal passage. Elsewhere across the CONUS, stable conditions should preclude thunderstorm potential. ..Dean.. 11/08/2025
