Areas affected...portions of west-central and southern Minnesota



Concerning...Severe Thunderstorm Watch 274...



Valid 052052Z - 052215Z



The severe weather threat for Severe Thunderstorm Watch 274

continues.



SUMMARY...The threat for large hail and damaging wind gusts

continues across newly issued Severe Thunderstorm Watch 274.



DISCUSSION...Several discrete/semi-discrete supercells have

developed just east of the SD/MN border as of 2030 UTC, with a

recent report of 1" hail and a measured gust of 56 kts. A corridor

of marginally steeper mid-level lapse rates (6.5+ C/km) analyzed via

latest objective analysis and modestly increasing mid-level flow

(sampled by the MPX VAD profile) immediately downstream of an

approaching shortwave trough will continue to promote the potential

for large hail as these storms propagate southeastward, with

damaging to occasionally severe wind gusts also possible. A locally

greater severe risk may evolve should a storm favorable interact

with a remnant outflow boundary from prior convection (evident on

visible satellite imagery and surface observations). 



With time, storms may evolve into one or more bowing

segments/clusters, which would favor an attendant increase in the

threat for damaging wind gusts. Convective coverage and severity

should then gradually wane later this evening as nocturnal

cooling/stabilization begins.
