Although a 4 to 5-day forecast for details is highly questionable, there exists some possibility of severe storms on Thursday. GFS is becoming more certain in the placement of the shortwave trough of interest. Thursday has a potential surface low setting up somewhere east of the Rockies-currently in the vicinity of S-central SD. Currently looks like a decent shear/moderate instability setup over eastern NE and E SD/W MN/NW IA. Probably too early to start a thread due to the high uncertainty, but for long-term planning, it is definitely worth looking at.
