045 ACUS11 KWNS 031015 SWOMCD SPC MCD 031014 KSZ000-OKZ000-031115- Mesoscale Discussion 1148 NWS Storm Prediction Center Norman OK 0514 AM CDT Mon Jun 03 2024 Areas affected...South-central KS and northwest OK Concerning...Severe Thunderstorm Watch 383...384... Valid 031014Z - 031115Z The severe weather threat for Severe Thunderstorm Watch 383, 384 continues. SUMMARY...A swath of 65-80 mph wind gusts is likely ongoing across a portion of south-central Kansas and should spread into parts of northwest Oklahoma through mid-morning. DISCUSSION...A 200-km long QLCS is ongoing across a part of southwest/south-central KS into far northwest OK. This QLCS has matured over the past couple hours with a history of measured severe wind gusts to 74 mph thus far. Strongest velocities have been noted within the apex of the line that has now shifted south of the US-54 corridor. Time-series of Vance AFB VWP has indicated some weakening of the south-southwesterly low-level jet, but it is still holding in the low 40s kts. While this leading wind surge may be tempered in time as it spreads into a more marginally unstable air mass farther east in south-central KS, an additional swath may develop along the trailing flank along the pronounced MLCAPE gradient in northwest OK. ..Grams.. 06/03/2024 ...Please see www.spc.noaa.gov for graphic product...
