SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1256 AM CST Wed Dec 24 2025 Valid 251200Z - 261200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL CALIFORNIA COAST... ...SUMMARY... Thunderstorms with potential to produce marginally severe wind gusts and perhaps a brief tornado, will be possible on Thursday along parts of the central California Coast. ...California Coast... A mid-level low and an associated trough over the eastern Pacific will gradually approach the West Coast on Thursday. Ahead of the trough, a stream of moisture will feed into California, where scattered thunderstorms are expected to develop during the day. At the surface, a front is forecast to move southward along the central California coast. To the south of the front near the coast, surface dewpoints will be in the 50s F. In addition, a 50 to 60 knot low-level jet is forecast to be in proximity to the higher surface dewpoints. This feature will create strong low-level shear along the central California coast, where some forecast soundings have curved hodographs and 0-3 km storm-relative helicity above 250 m2/s2. This could support a marginal severe threat, with cells that rotate within short line segments. A brief tornado or isolated severe wind gust will be possible. ..Broyles.. 12/24/2025
