337 ACUS02 KWNS 020656 SWODY2 SPC AC 020655 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1255 AM CST Mon Nov 02 2026 Valid 031200Z - 041200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM FAR EASTERN TEXAS AND CENTRAL LOUISIANA INTO SOUTHEAST MISSOURI AND SOUTHWEST ILLINOIS... ...SUMMARY... Scattered storms will occur from the Sabine and Lower Mississippi Valleys northward into the Mid Mississippi Valley on Tuesday. A few thunderstorms may produce damaging gusts, and a brief tornado cannot be ruled out. ...Discussion... A highly amplified upper trough will move out of the Plains and toward the MS Valley on Tuesday, with moderate southerly winds aloft. Height falls will occur over MO and AR during the day, and into IL and western KY and TN overnight. At the surface, low pressure will be located over southern MN, nearly stationary, with a front extending south across IA, MO, and into the Sabine Valley during the afternoon. Southerly low-level winds with 30-40 kt at 850 mb will aid moisture transport, with mid 60s F dewpoints as far north as the Missouri Bootheel. Rain and thunderstorms will be ongoing along the front early, though a diurnal uptick in intensity is expected from the Sabine River into southern MO. The primary mitigating factor on Tuesday will be widespread clouds, rain, and weak lapse rates ahead of the front. Still, at least isolated severe gusts, or a brief tornado or two may occur as shear profiles overall will favor rotation with storms along the front, or possible cells ahead of the front from LA into AR. ..Jewell.. 11/02/2026 $$
