ACUS01 KWNS 200600 SWODY1 SPC AC 200558 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1158 PM CST Wed Nov 19 2025 Valid 201200Z - 211200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE SOUTHERN PLAINS... ...SUMMARY... Isolated severe thunderstorms are possible later today into this evening across the southern Plains. Isolated hail, localized strong to severe gusts, and a tornado or two are all possible. ...Synopsis... A mid/upper-level shortwave trough initially extending from the Southwest into northern Mexico will eject northeastward across parts of the southern Plains later today. In response to this shortwave, a surface low will gradually deepen across the south-central Great Plains and move eastward through the period. A surface boundary draped across parts of OK/AR in the morning will lift slowly northward in the advance of the surface low. Upstream, another shortwave trough will drop southward along the Pacific coast and evolve into a closed midlevel low across southern CA by the end of the period. ...Southern Plains... Scattered storms will be ongoing across parts of the southern Plains later this morning, aided by a modest low-level jet and ascent attendant to the approaching shortwave trough. Initially moderate MUCAPE and effective shear of 40+ kt could support a few strong to locally severe storms during the morning from parts of eastern NM into west/central TX and OK, with a threat of isolated hail and locally gusty winds. Convection will persist through the day, resulting in generally modest heating and weakening midlevel lapse rates with time. As a result, while deep-layer shear will remain relatively strong across the warm sector, potential for organized convection downstream or in the wake of morning convection remains somewhat uncertain. Depending on the extent of heating and destabilization, at least some potential for isolated supercells and/or organized clusters could evolve during the afternoon and evening, with a threat of marginally severe hail and locally damaging wind. Some enlargement of low-level hodographs with time could also support a brief tornado threat from parts of central/eastern TX into eastern OK and western AR, if any surface-based supercells can be sustained. Farther west, some CAM guidance depicts development of a modestly organized convective line across NM into west TX during the afternoon/evening, in closer proximity to the ejecting shortwave trough. This could pose a threat of strong gusts, but it remains quite uncertain as to whether instability will be sufficient to support a severe threat with this scenario. ..Dean/Moore.. 11/20/2025 $$ |
