Evident banding starting to consolidate around the low-level vortex. Should be stacking now with the MLC. Pretty quick change in just the last hour or so.

Normandy Posted August 4 Share Posted August 4 Good news is this one will be in radar range the entire time until landfall. Still think it starts to intensify quickly tonight Link to comment Share on other sites More sharing options...

Still think it starts to intensify quickly tonight Hopefully it doesn't. Honestly, I'm just not feeling this one. But the rainfall will be prolific for sure.

GaWx Posted August 4 Share Posted August 4 Once again, the GFS goes offshore and then comes back to the coast (5th run in a row), this time just S of me (furthest S yet I think) giving me TS wind gusts combined with the very heavy rain probably causing many uprooted trees. I need a generator. Link to comment Share on other sites More sharing options...
Amped Posted August 4 Share Posted August 4 Bizarre complex track shown by the GFS and CMC. The troff lifts out and the 250mb flow shifts to the NW due to the ridge over the Central US. Then a tutt forms over FL while a ridge builds over the Carolinas, shifting 250mb winds back to the ESE forcing forcing the storm back to the west. Almost a 180 degree shift in the 250mb winds between hr 60 and 102 1 Link to comment Share on other sites More sharing options...

WxWatcher007 Posted August 4 Author Share Posted August 4 Some odd runs tonight. It looks like the GFS loops it back into the Gulf and regenerates its remnants before taking it up the coast. The wildly different solutions don’t create a lot of confidence. 1 Link to comment Share on other sites More sharing options...
dbullsfan Posted August 4 Share Posted August 4 I’m curious if at the 2 AM advisory it is more NNW, seems like most models have had it starting the turn north about now and it still appears to be headed NW. . Link to comment Share on other sites More sharing options...

I was just about to post that it looks like its made the move towards the north, if anything it took a little jog NNE. Link to comment Share on other sites More sharing options...

Idk what model it was, but one had it going over FL, then to SC, hangs out on the coast before going back inland, then back to the gulf before darting up the coast to New England. Like, wtf?

Like, wtf? 1. That was the crazy 0Z GFS. 2. 0Z Euro: for 1st run since the one from 48 hours ago, the model not surprisingly based on history/climo totally abandoned the come back to lower SC or GA NW move and instead is a more normal from that position NNE move from the ocean to the SC/NC border and then up the E coast to MD followed by a move offshore. It never moves even just W of due N the entire time once out of the Gulf except when it barely did so hours 96-102. That leaves only the GFS and the last CMC with the funky trek NW to WNW back into the SE. I’ll be looking for those to also abandon this craziness. Let’s see what the next runs of these models do. 2 Link to comment Share on other sites More sharing options...

Yeah I’m not really sure what to think. The ensembles were split between the op and a more progressive track. 1 Link to comment Share on other sites More sharing options...

NorthHillsWx Posted August 4 Share Posted August 4 It looks like a nascent eyewall is now forming. Once this develops a cohesive core it might be off to the races before landfall. Unlike that storm last year that peaked too early over the gulf, this looks like it will be strengthening into landfall. I really wouldn’t rule out this making a run at 85 kts 7 Link to comment Share on other sites More sharing options...
