Severe weather outlook: no organized severe threat

SPC AC 090050 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0650 PM CST Sun Nov 08 2026 Valid 090100Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected tonight. ...South Texas... An upper low over southwest Chihuahua, Mexico, this evening will progress toward the TX Big Bend overnight. Modest midlevel height falls preceding that feature will combine with persistent low/midlevel warm advection and a moist environment with MUCAPE of 500-1000 J/kg (per the 00Z BRO and CRP soundings) to yield an increase in thunderstorm coverage overnight. While no severe weather is expected, a strong storm or two capable of gusty winds is possible. ...Lower Great Lakes... Ongoing showers over portions of southwest Ontario are indicative of increased forcing for ascent associated with a vorticity maximum moving through that region. So far, convection has remained too shallow to support charge separation and lightning production. However, as the forcing begins to overspread the lower Great Lakes, sensible heat and moisture fluxes may be sufficient to yield deeper convective updrafts capable of sporadic lightning over far western NY and in the Tug Hill region. ..Mead.. 11/09/2026 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 0600Z
