Remnants of Emily could redevelop; Muifa batters Okinawa; Central U.S. roasts
Tropical Storm Emily degraded into an open tropical wave yesterday afternoon, after Hurricane Hunters could no longer locate a center of circulation at the surface. Through the morning yesterday, the storm appeared to lose most of its strong thunderstorm activity on the north side, and mid-level circulation was broad (tropical cyclones need a tight, coherent circulation to maintain themselves). Soon after the Hurricane Hunters took a pass through the storm, the National Hurricane Center demoted Emily from a tropical storm to a remnant low, while continuing to stress the rainfall threat to Hispaniola and eastern Cuba. Today it appears the center of the remnants are located just north of eastern Cuba in the southern Bahamas, although thunderstorm activity continues across eastern Cuba. Hispaniola probably saw rain and thunderstorms again early this morning, the strongest of which were on the eastern side of the island. New thunderstorm activity is starting to develop in the southeast Bahamas. Given Wednesday's rain gauge analysis from CPC, Hispaniola probably saw at least an additional 5 inches of rain yesterday.
Environmental conditions remain pretty much the same as yesterday, but are expected to become more favorable for Emily's remnants, and redevelopment of the storm is possible. Circulation from the low to mid-levels is still broad and tilting to the east with height due to the lingering moderate westerly wind shear. However, this shear is expected to dissipate some over the next 24 hours, and signs of this are already present to the west of the remnants. The dry air that has been following the storm since its inception has dissipated, as well.

Forecast for Emily's Remnants
Interestingly, the models have come into better agreement on the forecast for former Emily now that it has lost its surface circulation and degenerated into a tropical wave. The ECMWF, which has come out ahead in this forecasting game so far, is optimistic today that Emily will redevelop. Other global models—GFS, CMC, and FIM—also redevelop the storm. Consensus on timing of redevelopment seems to be when the wave reaches the northern Bahamas in 24 to 48 hours. At 12Z (8am EDT), the high-resolution HWRF model run forecasted a track that was furthest to the west of all the models, scraping eastern Florida as it travels northwest. The most probable track and intensity forecast that I see at this point is north-northwest movement over the next 24 to 36 hours, at which point the system will take a fairly sharp turn to the northeast and out to sea. Without an already established, coherent circulation, it appears unlikely that if Emily is reborn it will intensify into anything more than a moderate tropical storm. However, there is some potential as the system moves out to see that it could gain some strength and develop hurricane-force winds before it transitions into an extra-tropical cyclone.
Typhoon Muifa passes to the south of Okinawa, heads into East China Sea
The center of Typhoon Muifa passed to the south of Okinawa earlier this morning (Eastern time) and it continues to batter the islands with high winds and torrential rain. Local radar estimate rainfall rates as high as 80 mm/hour (approx. 3 inches/hour) in the strongest rain bands. Kadena Air Force Base near the city of Okinawa has been reporting sustained winds of 47 mph with gusts up to 72 mph. Muifa is expected to turn northwest today as it enters the East China Sea as a category 1 on the Saffir-Simpson scale, and then intensify into a category 2 as it passes close to eastern China. This morning, the forecast is that Muifa will probably not make landfall anywhere as a typhoon.

South-Central U.S. continues to bake
The extreme heat continues again today after 269 high maximum and 250 high minimum temperature records were set yesterday, 19 and 29 of which were all-time records, respectively. 206 of yesterday's records were 110°F or higher. Yesterday, Reuters was reporting that Texas was one power plant shutdown away from rolling blackouts. The forecast today doesn't look any better. Heat index values up to 125° are forecast in eastern Texas and the Lower Mississippi Valley.
Particularly toasty heat index values from yesterday:
• Mobile, Alabama: 120°
• Arkadelphia, Arkansas: 121°
• Bay St. Louis, Mississippi: 121°
• Memphis, Tennessee: 122°

I deal with Taiwan and China , importing. All I deal with speak good english and it just appears strange to me to see it this broken, like on tv. But I could be wrong. That is where my suspicion came from. My apologies if wrong.
Just looked at Cuban radar closest to Emily and she defintely has a circulation in bob of thunderstorms that is located squarely between the coast of Cuba and the central Bahamas. She may be more organized than the NHC stated at the 8pm advisory.
Deep South Dade...
Im going into lurk mode, just getting tired of what this blog is becoming...
Full with people who amp the systems over obcessively, and the growing and wide population of Trolls in the blog, just get tired of what goes on during some days in the blog, and prefer to post less due to this...
Wish we could start a new blog/renew DR. Masters' blog where this problem is diminished...
Back to lurking i guess.
Absolutely :)
"Sea-surface temperatures in the MDR are the third warmest on record, and models predict a continuation of very warm SSTs through the hurricane season."
The MDR sea surface temps are only behind last year and 2005 (not by much, though).
When you look at it fullscreen you can see the dark dot much better.
Looking very good for Dmin.

Some things you just have to let roll off your back. Nothing said here is really that big of a deal in the grand scheme of life. If you don't like it, ignore it and move on. Enjoy the blog...It's easy if you really want to.
23.1 N ; 77.2 W
agree 100%..new here and have never seen so much childish behavior in adults in my life. If I wanted that I would stay on facebook.
the convection associated to the remnant low pressure system of
Emily is affecting the Atlc waters N of Cuba and W of the
Bahamas S of 25n between 73w-78w. Scattered heavy showers and
thunderstorms roam this area. Also...a surface trough associated
to this system is analyzed from 28n74w to the low level center
near 23n78w into the Caribbean across central Cuba. Computer
models suggest this area of convection will continue to move NW
spreading over the waters near the NW Bahamas and eastern
Florida Seaboard over the next 24-36 hours.
lol I still think a phoney but I hope he stays safe in the storm.
Looks nice and centered tonight, what are the thoughts Patrap?
You're not wrong. The lack of both definite and indefinite articles is as sure a sign as any that it's merely some needy child seeking attention. FWIW, I put him/her ignore after the first obviously fake comment.
The hurricane season is fun here; there's so much going on. But in the much slower and mostly less exciting winter, I sure don't miss the trolls and the troll-ish.
Oh, well...
Well I won't say anything about NHC directly anyone/models can be wrong, but another thought crosses my mind , Dear not say the Gulf or even Fl., Oil/Gas prices go sky high , Breaking news on CNN the US just got an AA+ rating in credit, not the AAA it had , Blame it on the Reps or Dems, IMO its a free for all, though personally its common knowledge the GOP would do anything to try make Obama look bad,2012 a highly probable replay of 1996 IMO, just saying.......
What makes you think the majority of people on here are adults? Lol. I can almost assure you that a large portion of the blog members are in their teens. I'm in my mid-20s, though.
thanks for your positive choice of words, and i thank you for your advice in reacting in the blog...
Just have noticed more trolls to deal with...
Need to learn not to be so uptight about these sort of things, and let it just take it's coarse...
You either choose to respond or you don't.
SST
Divergence
Convergence
Moisture
Low Shear
Vorticity is improving through 500mb
Thunderstorms are getting more organized.
Looking at RGB and Cuba radar, there is some rotation but hard to tell if it goes to the surface. Be curious to find out what the HH aircraft finds out tomorrow... I am pretty certain it will get sent out.
Track is still a bit uncertain, but given the slow down in speed it may be ready to turn a bit more northward.
What do you think... last few frames of SAT loops look like it's starting to center up?
I actually judge for a living (don't ask me where) so I am always suspicious if the facts don't add up.... :)
The ends justify the means?
I never actually agreed with that, myself
Upper Divergence
Lower Convergence
Exactly my point....
Never even thought about looking at Cuban radar, good call...
