634 ACUS02 KWNS 081724 SWODY2 SPC AC 081722 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1222 PM CDT Wed Oct 08 2025 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe storms are not expected on Thursday. ...Synopsis... A mid/upper-level low is forecast to move slowly southward off of the Pacific Northwest coast on Thursday. The attendant large-scale trough over the Pacific Coast and adjacent eastern Pacific will move little during the period. Tropical Cyclone Priscilla is forecast to move north-northwestward off of the Baja California coast, as it becomes increasingly influenced by the western trough. Instability will generally remain weak across the region, but increasing moisture (associated in part with Priscilla) will support isolated to scattered storms across a broad region of the Southwest and Great Basin through the period. A cold front will continue sagging southward across parts of the Gulf Coast and FL Peninsula on Thursday. A midlevel shortwave trough will move southeastward from the TN Valley into parts of AL/GA. Lingering moisture/instability will support storm development across FL, especially the eastern/southern peninsula. Isolated storms may also develop in closer proximity to the approaching shortwave across parts of south AL and the FL Panhandle. A vigorous mid/upper-level low and attendant shortwave trough will move southeastward from the Canadian Prairies toward the Upper Midwest/Great Lakes region. Moisture return will be modest at best, but may be sufficient for elevated convection to develop during the evening, in advance of the approaching shortwave and upper low across parts of MN/WI/Upper MI. Somewhat greater elevated buoyancy may eventually evolve overnight from parts of IA into the lower MO and upper MS Valley, which could result in at least isolated development of elevated storms within a low-level warm-advection regime. ..Dean.. 10/08/2025 $$
