184 ACUS02 KWNS 160538 SWODY2 SPC AC 160536 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1236 AM CDT Thu Oct 16 2025 Valid 171200Z - 181200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE SOUTHERN AND CENTRAL PLAINS NORTHEASTWARD INTO THE LOWER MISSOURI VALLEY... ...SUMMARY... Thunderstorms with isolated hail and marginally severe wind gusts will be possible from Friday evening through the overnight period from the southern and central Plains into the lower Missouri Valley. ...Southern and Central Plains/Lower Missouri Valley... A mid-level trough will move eastward across the central Rockies on Friday, as southwest flow remains in place over much of the Great Plains. At the surface, a cold front will advance southeastward across the central Plains, as moisture advection continues ahead of the front. Surface dewpoints near the boundary are expected to reach the lower 60s F by Friday afternoon, which will contribute to weak destabilization from western Oklahoma northeastward into northwest Missouri. Forecast soundings near the instability axis have MLCAPE peaking in the 1000 to 1500 J/kg range during the evening. In addition, 0-6 km shear is forecast to be in the 35 to 45 knot range along much of the front. The resulting environment could support supercells with isolated large hail if discrete mode is favored. However, lapse are expected to remain weak suggesting any severe potential will remain marginal. A few severe wind gusts may occur as low-level flow increases ahead of the front during the evening. With instability and deep-layer shear being sustained through the night, a marginal severe threat should persist through late in the period. ..Broyles.. 10/16/2025 $$
