Valid 280628Z - 280830Z The severe weather threat for Severe Thunderstorm Watch 479 continues. SUMMARY...The risk for strong, potentially damaging wind gusts appears to be in the process of waning and this probably will continue as convection spreads east of WW 479. A new severe weather watch is not anticipated, but trends will continue to be monitored. DISCUSSION...The conglomerate surface cold pool has maintained a general eastward propagation in excess of 40 kt, accompanied by occasional strong surface gusts. However, trends in MRMS CAPPI, among other data, suggest that peak intensities within the more intense leading line are diminishing, as increasingly elevated updraft inflow becomes less unstable. These trends are expected to continue as convection spreads into the upper Mississippi Valley through daybreak. ..Kerr.. 06/28/2024 ...Please see www.spc.noaa.gov for graphic product...
