The thunderstorm chances gradually spread to the east and southeast as we go through Sunday afternoon and evening. At this point, it looks like our thunderstorm chance in the Twin Cities will hold off until sometime after 6 p.m. or so.
The NWS Storm Prediction center shows a marginal risk of severe weather this afternoon and tonight in the dark-green shaded area from southwestern Minnesota into northeastern Minnesota:
Marginal risk means that an isolated severe thunderstorm is possible.
