[html]MD 1695 CONCERNING SEVERE THUNDERSTORM WATCH 520... FOR SOUTHERN AND EASTERN NEBRASKA INTO FAR SOUTHEASTERN SOUTH DAKOTA AND WESTERN IOWA
Mesoscale Discussion 1695
NWS Storm Prediction Center Norman OK
0558 PM CDT Thu Aug 18 2022
Areas affected...southern and eastern Nebraska into far southeastern
South Dakota and western Iowa
Concerning...Severe Thunderstorm Watch 520...
Valid 182258Z - 190100Z
The severe weather threat for Severe Thunderstorm Watch 520
continues.
SUMMARY...Severe-weather risk continues with isolated storms moving
eastward/southeastward in and near WW 520.
DISCUSSION...Latest radar loop shows isolated intense updrafts along
a surface front now draped from far southwestern Minnesota to
south-central Nebraska. Ahead of this boundary, a corridor of
moderate instability (mixed-layer CAPE averaging 1000 to 2000 J/kg)
will continue to fuel isolated storms, with updraft organization
aided by veering/increasing flow with height yielding favorable
shear (in excess of 40 kt in the 0-6km layer). The most intense of
these storms will remain capable of producing hail greater than
golf-ball size, and wind gusts above 50 kt.
