Storm development/coverage is uncertain, though trends are being monitored for a possible watch. DISCUSSION...Visible satellite imagery shows increasingly agitated high-based cumulus developing along a dryline extending across the TX South Plains. Radar data from LBB also shows continued attempts at convective initiation within the zone of low-level ascent. If a couple storms can develop within this corridor, a deeply mixed boundary layer (characterized by an inverted-V sounding) and sufficient instability would promote severe downbursts (and possibly some severe hail) with any sustained high-based storms. Storm development/sustenance and overall coverage is somewhat uncertain, though trends are being monitored for a possible watch. ...Weinman/Mosier.. 06/17/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-_vUb2y3y3F7kbTUZUgRPTSVgSCQgDJCySpn9BJDA7dG1HfRAYjIws8cW7NgxsMRmhgkOEk8C= D8LrTJYvaOkkGewDf0$ for graphic product...
