This line is expected to advance east of ongoing Severe Thunderstorm Watches 436-437, necessitating a downstream Severe Thunderstorm Watch issuance. DISCUSSION...A mature QLCS continues to propagate eastward, with recent reports of measured gusts in the 50-68 mph range in the past hour or so. This line will continue advancing eastward into a moderately unstable airmass, which will support additional strong to potentially severe gusts. As such, a downstream Severe Thunderstorm Watch will be needed soon. ...Squitieri/Smith.. 06/18/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!9wgbOZD0u-wkjt9RLHc9CyhCpO-AxiIrd92XD7zaWCnueSM6F5TalZMQQbuU4FlnbETZ05nw1= ZiB7nMP2PhXzl7Nnkw$ for graphic product...
