Overall, the vLAPS is performing a bit better today.  It’s still a bit too slow with the linear band of convection, again likely not catching the cold pool that has accelerated east with the convection in reality.  But it does hint at storm structure, with generally a disorganized line with some embedded bowing structures, some of which have been severe given decent low-level lapse rates and inverted-v soundings. So overall, it’s done pretty well and certainly useful in an operational setting.
