Valid 170423Z - 170600Z The severe weather threat for Severe Thunderstorm Watch 629 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 629. Damaging gusts remain the main threat with these storms over the next few hours. DISCUSSION...An MCS has materialized from congealing storms over the last few hours, with strong wind gusts over 50 mph recently reported. Preceding the eastern portion of the MCS is a cooler airmass, characterized by surface temperatures in the upper 70s to low 80s F. However, along the western periphery of the MCS track are warmer surface temperatures between 85-90 F, which also reside beneath the eastern periphery of a modest LLJ and accompanying WAA. As such, the portion of the MCS cold pool propagating into this airmass has the greatest chance for supporting stronger updrafts and corresponding downdrafts, which may penetrate the increasing MLCINH. Here, a few additional strong to severe gusts may occur over the next few hours. ...Squitieri.. 08/17/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!4LyQdRqIQDHQmbRdSybapCMTuEbXNrVvDtaOlwnpwQ84cYAIZzq_VFrkKVNKTW8SUW4Kwtidq= D6FdXtIhW8u4ag1ayw$ for graphic product...
