Probabilities are meaningless. It has 100% already developed and has likely peaked. Mentioning the a 20% chance that the NHC calls it TS or STS would have little meaning and would be pointless.

Looks like it is about to move inland on radar.

Something I feel like I should know already, but there's a stationary line that the clouds seem to be going up and over, is that a sample of about where the front is located?

The United Surface Analysis shows a front attached to it from the east.

But yes, this is like a PTC Eight paradox.


Sure, it is non-tropical originating from an old frontal boundary. But now with strong convection constantly building just north of the center there it is getting a bit more tropical. I have seen instances like this where they mark a potential STS to account for the extratropical nature of the low. VA Beach is going to have some nasty weather late today.

We've been getting hammered for 12 hours. Multiple flash flood warnings and power is flickering. This is WAY stronger than the supposed tropical storm we had over a month ago.
