380 ACUS01 KWNS 140031 SWODY1 SPC AC 140030 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0730 PM CDT Mon Oct 13 2025 Valid 140100Z - 141200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTH-CENTRAL COASTAL CALIFORNIA... ...SUMMARY... Locally damaging winds are possible late tonight along parts of south-central coastal California. ...01z Update... Strong upper low is currently located off the northern CA Coast, just southwest of EKA. This feature is moving south as a 100+kt 500mb jet digs along the back side of this trough. Later tonight, left exit region of the jet max will approach the southern CA Coast and this should encourage low-topped convection along the cold front. Forecast soundings suggest only a few hundred J/kg MUCAPE can be expected in advance of the front as lapse rates will only be on the order of 6 C/km. Strong 0-6km shear favors the potential for updraft organization, thus low severe probabilities for wind, and perhaps a brief weak tornado will continue overnight. ..Darrow.. 10/14/2025 $$
