Yup...given the weak mid-level lapse rates we need to maximize sfc heating so we can achieve maximum instability. Mid-level lapse rates may also improve some as the day progresses. Could see them in the 6-6.5 C/KM range which isn't terrible, especially around here.
HRRR continues to be rather inconsistent with its run-to-run evolution, however, I think we have a solid idea on how today evolves. We see some early stuff move through (which may also set a boundary for later) then by mid-to-late afternoon we see rapid development and a quick organization into a line with a focus on where the boundary resides.
