Valid 190427Z - 190600Z The severe weather threat for Severe Thunderstorm Watch 514, 515 continues. SUMMARY...Isolated strong to severe thunderstorms will continue to pose a risk for damaging gusts and large hail another couple of hours. DISCUSSION...Isolated thunderstorms from southeast ND into eastern SD and northeast NE will continue to shift southeast within an instability gradient. Moderate instability and vertical shear will support strong storms for another couple of hours. With time convection will encounter a more hostile downstream environment, due to increasing inhibition and weakening instability with eastward extent. New watches downstream from WW 514 and 515 are not expected. ...Leitman.. 07/19/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!4M3e3CdxgOPgv6gn7vT7XukGGBU_aopW6tKX4lKlXPcFp56eUOLN4doy6QOIeR6oDCnu4O5xZ= 2Rzhpxp_rHu5Nmoa3c$ for graphic product...
