We've been pulling our hair out this morning trying to decide on whether to head NW into S Dakota, where there is relatively good moisture, and strong surface convergence - or SSW towards SE or Central S Nebraska, where the chance of storms is much lower, but the parameters suggest that should something develop here, it would be isolated, severe, and bring the risk of a tornado.
After much deliberation and chart watching, we've opted for the Nebraska target. This is partly because there was a consensus that missing a tornadic supercell would be more gutting than missing some high based supercells! However, I'm sure that if/when storms develop in S Dakota, we'll still be annoyed! Oh well - the perils of storm chasing!
Tomorrow is our last chase day, and at this stage, SE Nebraska looks like the best area, so if nothing else, at least we should end up in a reasonable spot by the end of today.
