SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CST Tue Dec 23 2025 Valid 251200Z - 261200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ALONG PARTS OF THE CENTRAL AND SOUTHERN CALIFORNIA COAST... ...SUMMARY... Thunderstorms with marginally severe wind gusts and perhaps a brief tornado, will be possible on Thursday along parts of the central and southern California Coast. ...California... A large-scale mid-level trough will move slowly eastward toward the California coast on Thursday. Strong flow aloft will maintain a stream of mid-level moisture into the region, as large-scale ascent continues to support scattered thunderstorm development. At the surface, a cold front will approach the central California coast during the day. Surface dewpoints ahead of the front will be in the 50s F, southward into parts of southern California. This should be enough for weak destabilization near the coast during the late morning and afternoon, which could result in a marginal severe threat. Strong low to mid-level flow and modestly steep low-level lapse rates could support isolated severe wind gusts and perhaps a brief tornado. ..Broyles.. 12/23/2025
