Might be a product glitch but last frame of RAMMB shows no lightning strikes at center

I find the lightning strike stuff is usually a frame slow updating on RAMMB.

Eye is trying to re-establish itself within the convection. If it can do that, probably will maintain intensity up until landfall. I don't anticipate any strengthening.

There was no lightning for about 20 mins or so. Started up again. Edit: 15 mins loop below.

For those better versed, when they talk about the shear shredding the cane. This increases tor chances correct? Colder dry air injection + shear = higher tor threat.

Eastern side of eye now blowing up with high cloud tops and convection

expanding quickly on the western flank 

Made it through another ERC without too much degradation, which is bad news. That inner core is impregnable. Could even see some minor intensification later this afternoon, which would be quite a feat given the environment it's currently in.

From a purely tropical perspective: the "front right" quadrant of a tropical system will provide an enhanced shear & helicity environment for storms. That's where you'll often find low-topped/mini-supercell development like we're seeing today across S Florida. 

The "shear" that's increasing w/respect to Milton doesn't necessarily provide better shear for tornadogenesis. The boundary itself that's been draped over the state will enhanced some local probabilities, but the main driver will be the fact it's in the front right quadrant. 

Others can feel free to correct me given I'm not exactly an expert w/tropical met [I've dabbled w/2 courses].

I'm not a met but I agree with this.  When we talk about shear for tornado production, we're primarily focusing on low-level shear.  When we talk about shear having a negative impact on a hurricane, we're typically talking about shear higher up in the atmosphere.
