The severe weather threat for Severe Thunderstorm Watch 381
SUMMARY...Strong storms will spread across southeastern portions of
DISCUSSION...Convective outflow has surged 10-15mi ahead of trailing
convection along the southwestern flank of IA MCS. Latest radar data
continues to suggest large hail accompanies two significant updrafts
west of the Missouri River near OMA. This activity appears to be
partly supported by a notable short-wave trough that currently
extends along the SD/MN border into extreme eastern NE. As the
trough shifts east the back edge of strong convection should shift
east into southwestern IA where gradual weakening is expected over
the next few hours.
