SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0732 PM CDT Wed Oct 08 2025 Valid 090100Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast tonight. ...01z Update... Dominant upper ridge remains anchored over the southern Plains early this evening. This flow regime continues to favor a few minor disturbances, and seasonally high PW values, advancing around the periphery from northern Mexico into the Four Corners region. One such feature appears partly responsible for ongoing scattered convection across eastern AZ into northern NM. Some risk for lightning continues across this region as 00z soundings from TUS/FGZ/ABQ all exhibited fairly steep lapse rates with adequate buoyancy for thunderstorms. Downstream across the southeastern U.S., progressive upper trough is advancing off the Middle Atlantic Coast early this evening. Associated surface front has advanced to coastal NC/SC, extending into the FL Panhandle. Isolated thunderstorms will be noted along this boundary early this evening and then shift offshore with the wind shift. ..Darrow.. 10/09/2025
