MD 1814 CONCERNING SEVERE THUNDERSTORM WATCH 541… FOR MUCH OF CENTRAL AND WESTERN UTAH INTO FAR SOUTHWEST WYOMING
Mesoscale Discussion 1814 NWS Storm Prediction Center Norman OK 0256 PM CDT Wed Sep 21 2022 Areas affected...much of central and western Utah into far southwest Wyoming Concerning...Severe Thunderstorm Watch 541... Valid 211956Z - 212130Z The severe weather threat for Severe Thunderstorm Watch 541 continues. SUMMARY...The risk for damaging wind gusts and isolated hail will continue through this afternoon. DISCUSSION...As of 1945 UTC, regional radar and satellite imagery showed scattered strong to severe thunderstorms ongoing across WW541. A few storms have shown mid-level mesocyclones which may enhance the potential for damaging wind gusts and isolated severe hail. Additional development continues across western UT as the main upper low continue to overspread the destabilizing airmass this afternoon. Additional organization into supercells or clusters is possible with effective shear of 40-50 kt and the sufficient buoyancy. The greatest severe risk likely remains focused across mostly northern portions of UT where the greatest coverage of storms is expected later this afternoon/evening. However, the risk for severe wind gusts (some significant) and isolated severe hail will remain possible with strong convection across all of WW541. ..Lyons.. 09/21/2022 ...Please see www.spc.noaa.gov for graphic product...
