Valid 271854Z - 272030Z The severe weather threat for Tornado Watch 145, 146 continues. SUMMARY...As severe storms in north-central Oklahoma and south-central Kansas spread east late this afternoon, an additional tornado watch will likely be needed. DISCUSSION...The airmass ahead of severe storms in south-central KS and north-central OK continues to destabilize as surface temps have warmed in the upper 70s to low 80s across most of eastern OK into far southeast KS. While low-level shear within this part of the warm-moist sector is relatively modest per INX VWP data, it will strengthen based on upstream TLX data. A mix of discrete and semi-discrete supercells occasionally embedded within clusters should spread east-northeast through late afternoon. As this occurs, all severe hazards will be possible, some of which may be significant. ..Grams.. 04/27/2024 ...Please see www.spc.noaa.gov for graphic product...
