Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Mon May 29 2023 01:06:43 ACUS01 KWNS 290106 SWODY1 SPC AC 290105 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0805 PM CDT Sun May 28 2023 Valid 290100Z - 291200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PORTIONS OF THE CENTRAL AND SOUTHERN HIGH PLAINS VICINITY... ....SUMMARY... Isolated strong to severe thunderstorms are possible across parts of the southern/central High Plains vicinity. ....Synopsis... A shortwave trough within the northern Plains will continue to the northeast this evening and into Monday morning. A subtle shortwave trough appears to be aiding in storm longevity in parts of the southern High Plains. Generally widely scattered convention will continue for a few more hours within the broader High Plains region. Some cold pool organization in the northeast Texas Panhandle may provide greater wind gust potential this evening. ....Texas Panhandle and South Plains... A cluster of storms developed in southeast Colorado and is progressing into the Texas Panhandle. This activity was preceded by isolated supercell activity that has shown very little movement. While steep mid-level lapse rates are noted on the 00Z observed AMA sounding, outflow from earlier convection has stabilized the boundary layer somewhat as evidenced by billow clouds in the eastern Panhandle in late afternoon visible satellite imagery. Despite slightly greater potential for a strong to severe gust with this cluster, coverage of such wind will not likely be substantial. In the South Plains, isolated supercell activity has persisted over the last couple of hours with large hail being the primary hazard. Another cluster in east-central New Mexico may move into the region. Damaging wind gusts and large hail would be the primary threats. ....Central High Plains Vicinity... Scattered convection continues from northeast Colorado into western South Dakota. This activity should wane with the loss of daytime heating and the departure of the shortwave trough to the northeast. Marginally severe hail and wind damage may occur with the strongest activity. ...Wendt.. 05/29/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
