I feel really confident about flooding and heavy rain, Winds could be meh, but the flooding could be just terrible. Intensity over the next 24h is the big q mark.

Surge should be quite bad. You better hope it doesn't blow up tomorrow & Saturday.

Models are always off on intensity (usually too weak).

Can't really look at those maps with these.. usually way underdone  with tropical systems

Yes tropical rainfall is of the "warm rain" variety not the "cold rain" we typically think of in most cases. I have no idea if these numerical models take into account the differing cloud physics and precip processes that occur, so I can't speak to that. But regardless, yes it's why radar has a hard time at picking up on proper dbZ values in tropical systems

Posting because this was actually alluded to a bit this morning and we did see some hints of a possible downshear reformation that looked to be ongoing from recon. Not saying RI is happening for those lurking, but rather highlighting a possible reason we see intensification once this starts paralleling the coast.

I think goal post is CT/RI line to the Cape with more hydro related concerns vs wind. However it won’t take much wind to take down some tree after today. 
 

Interesting to track and easily could go out to sea

I’ll be honest .. I think it’s a low chsnce we can hook it back into C CT. I can see a hook over E LI to GON then a turn NNE. Right now .. my feeling is LF E tip LI into RI . To me the biggest question is .. how strong is it at that point? That’s just how I interpret it now . Low confidence

Eh… I’ll sell a foot of rain. Even if it stalls

Double maybe triple that if it stalls.

I guarantee you someone sees over a foot with that track. West Hartford got 5" of rain today alone. It would rain much longer than today.

80-90mph at best.

I don't think it would be isolated...probably be within some sort of narrow swath

This. Tropical is a lot different from the storms we usually see. In the right setup, you can get huge totals in a broad area, even from a weak or decaying system. We've actually seen a lot of these in recent years in the US.

I'll also sell a foot of rain.  I'd have to see to believe that around these parts for sure.  If it should happen I'll give props to folks.

Expand  

A quick moving tropical storm drops swaths of 6" so.. One that pours for a straight day would easily achieve those higher totals
