685 ACUS01 KWNS 131244 SWODY1 SPC AC 131243 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0643 AM CST Thu Nov 13 2025 Valid 131300Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Minimal thunderstorm chances are evident today over parts of central California. Severe weather is not forecast. ...Synopsis... A cyclone, embedded within the southern periphery of a large upper trough, will gradually progress toward the central CA coast throughout the period. Moist southwesterly flow aloft ahead of this cyclone will continue to spread eastward/northeastward across CA and OR. Modest elevated buoyancy is anticipated within this moist plume, supporting the potential for deeper convective elements capable of isolated/sporadic lightning flashes. Strong vertical shear is in place, but the very weak buoyancy and transient nature of any deeper updrafts will limit its efficacy. Farther east, surface high pressure will remain over much of the eastern CONUS, promoting dry and stable conditions. Some modest moisture return is anticipated across the southern Plains and Lower MS Valley but warm temperatures aloft and negligible forcing will preclude thunderstorm development. ..Mosier.. 11/13/2025 $$
