So we're in to the range of the NAM nest now, and it has been emphatic for several consecutive cycles now that a strongly forced convective line will move through the area early Wednesday evening. But it's also been emphatic that the line will not be surface-based, and most of the guidance I've seen agrees with that, so the chances of taking advantage of the excellent shear profiles seems low. That said, the GFS is trying harder to find a tiny bit of sac-based instability, so I won't totally close the door, even though I'm really hesitant to consider the GFS it wants to scour out the low-level cold air.
