KANSAS CITY, MISSOURI — A potentially significant and rare dual Mesoscale Convective System setup is taking shape for Monday June 1, 2026, with the StormNet-v4 Wind Probabilities model initialized at 18z May 29, 2026 and valid from 18z June 1 through 06z June 2 showing two distinct and intense wind threat zones developing simultaneously — one across the central plains and one across the mid to deep South — with forecasters noting they would not be surprised if one or both systems reach derecho criteria.
StormNet Model Shows Medium to High Wind Threat Across Central Plains MCS Zone
The StormNet-v4 Wind Probabilities map shows the first and most intense of the two circled MCS threat zones positioned across the central plains, with a green medium wind threat core reaching values of 0.5 or higher surrounded by blue low to medium probability shading extending across Kansas, Nebraska, and Missouri. The red circle annotated by forecasters on the map encompasses this central plains MCS zone, with an arrow pointing toward the green core indicating where the highest wind damage probability is concentrated for the Monday event.
This central plains MCS carries the higher wind threat probability of the two systems on the StormNet output and represents the more organized of the dual MCS signals for Monday, though both systems are being taken seriously as potential derecho producers.
