Strong heating is going to be a key today given the very poor mid-level lapse rates and the warm mid-level temperatures. Low-level lapse rates aren't too bad (7-7.5 C/KM) with RAP even generating pockets of 8 C/KM. This isn't bad when looking for wind potential, however, 2-6km lapse rates need some work. Wind shear is more than sufficient (30-40 knots of effective/bulk shear) to get storms to organize.
Getting dewpoints more in the 73-74F range would go along ways, however, not sure if we see much dew point pooling today. Basically this would be a difference between more localized severe and something more along the lines of a swath of wind damage reports.
