MISO publishes cleared prices, not probabilistic forecasts, so no band is shown. Wind-forecast misses in the north and weather-driven load misses in the south are the dominant sources of day-ahead error.
MISO settles trade against eight hubs; Indiana Hub — the old Cinergy hub — is the benchmark the Midwest trades against. This page plots it alongside Michigan, Minnesota, and Louisiana, so the market's whole north-south axis is on one chart.
MISO's footprint runs from Manitoba to the Gulf through chronically constrained transfer paths. Minnesota clears against wind; Louisiana clears against gas and industrial load. When the ties bind — a northern wind lull, a southern cold snap — the hubs price apart, and that spread is the market's congestion map.
MISO's day-ahead market is a financially binding auction clearing the day before delivery. Its price carries the market's expectation plus risk premia, which is why scoring it against settled real-time — as the scorecard above does — is the honest way to read it.

MISO's benchmark trading hub, inherited from the old Cinergy hub — the reference price for the industrial Midwest and the point most MISO forwards settle against.
Congestion on the north-south transfer paths. Minnesota clears against the wind belt, Louisiana against Gulf gas and industrial load, and the transmission between them is finite. When it binds, the hubs decouple — the spread table shows by how much right now.
Day-ahead clears on forecasts and hedges; real time clears on delivery. In MISO the biggest movers are wind-forecast misses in the north and fast weather in the south — the scorecard above measures the resulting divergence over the settled window.
