SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0643 PM CST Fri Jan 09 2026 Valid 100100Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EAST TEXAS TO CENTRAL ALABAMA... ...SUMMARY... Scattered severe thunderstorms are forecast across southeast Texas into the central Gulf states tonight. A few tornadoes and damaging wind gusts are possible. ...01z Update... Notable short-wave trough is beginning to eject northeast across the central Plains early this evening. Water vapor supports this with the center of circulation near DDC. 500mb speed max affiliated with this feature will strengthen and translate across north TX-southern MO-central IN by the end of the period. This evolution will result in negligible height changes along/near the Gulf coast overnight. As this feature advances east, LLJ is expected to increase across LA later this evening, strengthening into northern AL by 10/12z. Low-level warm advection has proven instrumental in convective development much of the day with scattered thunderstorms persisting across the lower MS Valley. However, some increase in convection appears to be occurring across east TX as the southern influence of the ejecting short wave glances this region. Earlier thoughts regarding severe potential remain. 00z sounding from LCH exhibits strong shear and ample buoyancy for supercells. Latest thinking is scattered-numerous showers/thunderstorms will persist along a corridor from northern LA into central MS with the potential for some uptick in intensity overnight as the LLJ strengthens. ..Darrow.. 01/10/2026
