Mesoscale Discussion 1328 NWS Storm Prediction Center Norman OK 0636 PM CDT Tue Jun 18 2024 Areas affected...Southwest into central KS Concerning...Severe Thunderstorm Watch 434...435... Valid 182336Z - 190100Z The severe weather threat for Severe Thunderstorm Watch 434, 435 continues. SUMMARY...Some threat for severe gusts, hail, and a brief tornado may persist into mid evening. DISCUSSION...A frontal band of strong to severe storms from southwest into central KS has been gradually shifting eastward late this afternoon into the early evening. While some consolidation of storms has occurred, multiple embedded cells persist, which will continue to pose a threat of isolated hail. Transient low-level mesocyclones continue to be noted on radar across southwest KS, and some threat for a brief tornado could persist within the vorticity-rich environment near the front. However, a general tendency for strengthening and expanding outflows may result in severe gusts becoming an increasingly prominent hazard across the region, as noted with a recent 60 kt gust in Russell, KS. A continued tendency toward backbuilding and redevelopment may continue through the evening across southwest KS, with a southerly low-level jet expected to remain focused across that region. Farther north, there may be some tendency for gradual weakening with time later this evening from north-central into northeast KS. However, some severe threat could persist beyond the 01Z expiration time of WW 434, potentially necessitating local watch extension or new watch issuance. ..Dean/Edwards.. 06/18/2024 ...Please see www.spc.noaa.gov for graphic product...
