Weak low from what I can see right off the southern NC coast. Not much happening with it yet on the run. 

i don't think it will do much.  By the time it pops the Bermuda high to the SE of 92L pops back up and will funnel it OTS as the GL low and leftover Harvey spin around.

Better that way than too far east though right? I'm rooting for a tropical moisture plume getting engaged with a ML front. 

there is still a chance for something after 192 as the base of that trough gets down to the gulf

The  12Z Euro is terrorizing on so many ways.  I could obviously see worse cases for the USA like a Cat 4/5 stall over Miami or New Orleans  but this is a very bad situation.  News media will be playing big catch up.  Probably talking about a Cat 2 hurricane hitting Texas coast.  The stall or re-emergence over the Gulf and the slow ENE trek is the scariest part...

Heh, Day 8 looks a little fun up here. Low slides east and gives us rain and breezy conditions verbatim. Fantasy range, but the idea makes sense in the long term. That was one hell of a Euro run lol. 

Nice lateral. lol. This is what I'm rooting for...LOL

Remnant track east of the MS river with a mega plume of deep tropical moisture for 24-48 hours. Training rains and embedded severe the whole time. Then the UL center tracks overhead. Synoptic rains, winds, and severe as it passes to the coast. That's not too much to ask is it? If it is then this...

Perfect track with the remnants running the apps. Trop force gusts and torrential rains as the center boogies through.

BTW, everyone-- here's a good one to research for our area:

https://en.wikipedia.org/wiki/1896_Cedar_Keys_hurricane

...as in how did a 960-mb hurricane hitting the Gulf coast of FL manage to bring hurricane-force gusts up here with significant property damage and storm surge? Hazel-type extratropical transition?

Looks like real fast movement... and wow in DC (link in post above)

In Washington, D.C., the storm's approach late on September 29 was marked by nearly continuous cloud to cloud lightning.[6] Five-minute sustained southerly winds reached 66 mph (106 km/h),[7] and peak gusts approached 100 mph (160 km/h); barometric pressure fell to 987 hPa (29.15 inHg). At the time, it was the worst storm to ever affect the city.[27][72] The winds brought down signs, awnings, trees, and brick walls, while unroofing homes, toppling church steeples, and shattering windows.[72] Electric, telegraph, and telephone utilities were lost.[15] The destruction was not uniform, as poorly built structures often survived unscathed in the vicinity of much stronger buildings that incurred significant damage.[76] It was deduced that the strongest gusts occurred in narrow "streaks".[27] Approximately 5,000 trees were destroyed in the city,[28] many of them being snapped 10 to 15 ft (3.0 to 4.6 m) above the ground.[7] Some of the worst damage occurred in cemeteries, such as the United States Soldiers' and Airmen's Home National Cemetery, where 300 trees were prostrated. In a few cases, the fallen trees unearthed underlying coffins.[77]

Needless to say Harvey is doing very well today. Hope people down there are prepared. As for us up here... Long range but, assuming that the track is right, I hope to see at least severe level wind gusts which has a little bit more than a 0% chance of happening :(. But still, if models do latch on to Harvey-Harv's remnants coming this way it will be interesting enough to track..... I guess........ Aaaaah you know I'll be tracking it anyways.

Also in VA and MD:

Montgomery County was hit particularly hard; the storm wrecked an amusement park in Bethesda, forcing it to permanently close, while Gaithersburg was "most disastrously wrecked". 

 

--Coincidentally, this is also how I would describe my state on Friday nights in college.

I look at it like this...yes, we get the once a decade (or whatever) tropical that hits the EC and tracks up here. Most end up east of us so it's pretty boring. But EC hits are not very common with impacts through the cities and west. Gulf storms have a better history at giving us impacts through the cities and westward. Not as exciting as an NC landfall or something like that but Gulf storms can be pretty fun here if you have proper expectations.

Very true. But I'm just an extreme wind weenie :lol:

I'd love to see Harvey get ingested into the westerlies then come here and move very slowly. Floods are very fun.

I am THE Quintessential flood weenie!

Then a week later, we get to do it all over again! There's only one thing better than a life threatening devastating flood.

TWO OF THEM! Kind of like Connie and Diane! Now that was two ladies that loved to par-tay!
