MD 2011 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR SOUTHERN AND EASTERN MINNESOTA AND NORTHERN IOWA.
Mesoscale Discussion 2011 NWS Storm Prediction Center Norman OK 0346 AM CDT Tue Aug 27 2024 Areas affected...southern and eastern MInnesota and northern Iowa. Concerning...Severe potential...Watch unlikely Valid 270846Z - 270945Z Probability of Watch Issuance...5 percent SUMMARY...The severe weather threat continues to decrease across portions of the Upper Midwest. No downstream watch is anticipated. DISCUSSION...A few strong to potentially severe storms moved through watch 654 over the past few hours and are now exiting eastern portions of the watch. Convective trends are down and as storms continue to outrun the better deep-layer shear, expect this trend to continue. Nonetheless, a very unstable airmass remains ahead of these storms (4000 J/kg MUCAPE across northern Iowa). Therefore, occasional stronger updrafts capable of isolated severe weather remain possible, albeit unlikely. Given the weakening trend, a downstream watch will not be issued east of watch 654. ..Bentley/Edwards.. 08/27/2024 ...Please see www.spc.noaa.gov for graphic product...
