Valid 162219Z - 170015Z The severe weather threat for Severe Thunderstorm Watch 500 continues. SUMMARY...A supercell capable of large/very large hail and severe wind gusts will likely continue to the south/southwest in central Kansas. Additional development is possible in west-central Kansas. Later this evening, the low-level jet could promote storm development in east-central/southeastern Kansas. DISCUSSION...A large supercell in central Kansas near I-70 has produced hail of 1.25-3 inches in the last hour or so. Measured severe wind gusts have also been observed along the western flank of the storm (recently 70 mph in Russell). Current observational trends in central Kansas show a pocket of dry/well-mixed air in the vicinity of Wichita. Greater moisture exists along an axis from Great Bend to Pratt. It is likely that this supercell will continue to track south to perhaps a bit southwest this afternoon. Strong effective shear and buoyancy will continue to support a threat for large/very large hail and severe wind gusts. Additional convection has attempted to develop and mature farther west along the outflow boundary. Should that occur some upscale growth is possible and severe winds would become more probable. Low-level shear is weak per area VAD profiles, and the tornado threat is generally low as a result. The exception would be along the outflow into southeastern Kansas, though storms are not likely to develop there in the near term.=20 Eastern portions of WW 500 will likely not see much activity in the short term. With a modest increase in the low-level jet expected this evening, the outflow boundary will need to be monitored for convective development. Forecast soundings suggest those potential storms would pose a similar threat of large hail and severe/damaging winds. ...Wendt.. 07/16/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5bcj9FayQesWFbEIDdri72JJiROMBU89YOCTlr3HXN3pyGAECKlm9oVrnFYmn7om8UywSEGgP= E6lfc4Mwm38d0i1ssM$ for graphic product...
