Ernesto, Florence, And Severe Weather At Home
by emcf30 Sun Aug 05, 2012 9:23 am
ERNESTO
Despite appearing strong in satellite imagery, Tropical Storm Ernesto has not become any more organized, in fact, he has weakened according to data gathered from a reconnaissance plane.
Boy oh boy can looks be deceiving. Yesterday, a lot of people, including myself, was wondering how could Ernesto be exploding into what was thought to be a hurricane days before any model depicted. How could he develop against all odds moving 24 mph at times. How could Ernesto develop when he was moving so rapidly through the Caribbean Graveyard when history and Climatology told us different. How could this be happening. Well it was not.
Ernesto had what appeared to be a circulation that was centered under the Central Dense Overcast and good venting, or outflow channels developing. In fact, Ernesto was performing one of his best illusion acts on us. What we see is not what we get.
Well in short, Ernesto was running to fast because of the strong tradewinds and left his top behind somewhat. The circulation at the surface is very ill defined. Additionally, the surface and the mid level circulations are not vertically stacked. Until these circulations are stacked, Ernesto WILL NOT strengthen, no matter what the appearance is on your computer screen.
Ernesto is still expected to slow down it's forward movement as the sub-topical ridge begins to weaken and breakdown. As we have been stating for the past few days, this is when Ernesto is expected to take full advantage of the environment he will have available to him and begin to strengthen. This will be an area where the tradewinds will diminish, little shear, and very warm SST's and Ocean Heat Content is available. Still expect this to become a Hurricane before coming ashore.
Lets take a look at the latest intensity forecast.

Here is the latest Early Track Guidance
The Global and Tropical models now agree of an Mexican hit before reentering the BOC or the GOM. After that, they are still diverged. This is due to the storm not developing more quickly and the weakness in the ridge will have less of an affect on Ernesto. From the get go of this system, we have said the strength will determine a United States or an South American Hit. This still holds true, IMO.
The GFS Ensembles are now mostly all saying a total Mexico problem from Ernesto.
The current OFFICIAL track issued by the NHC.
Current loop of Ernesto
Ernesto still has the potential of becoming a bad storm in the coming days. Everyone still needs to watch this system closely from the Northern Gulf Coast States all the way down to Mexico and Belize, no matter what the current status of Ernesto is at the moment, or in the next 36 hours. Ernesto still has the possibility of becoming an open wave before re-strengthening once again.

FLORENCE
Tropical Storm Florence was designated yesterday by the NHC.
TROPICAL STORM FLORENCE DISCUSSION NUMBER 6
NWS NATIONAL HURRICANE CENTER MIAMI FL AL062012
500 AM AST SUN AUG 05 2012
THE STRUCTURE OF FLORENCE HAS EVOLVED OVERNIGHT FROM A CENTRAL DENSE
OVERCAST TO MORE OF A SHEAR PATTERN...WITH THE LOW-LEVEL CENTER
ESTIMATED TO BE NEAR THE EASTERN EDGE OF THE DEEP
CONVECTION. THIS CHANGE IN STRUCTURE IS LIKELY THE RESULT OF
MODERATE SOUTHEASTELY VERTICAL WIND SHEAR. DESPITE THE STRUCTURAL
CHANGES...DVORAK T-NUMBERS AT 0600 UTC WERE ESSENTIALLY THE
SAME AS BEFORE...THEREFORE...THE INITIAL WIND SPEED REMAINS 50 KT.
FLORENCE COULD GAIN SOME STRENGTH OVER THE NEXT 24 TO 36 HOURS...
HOWEVER...SIGNIFICANT INTENSIFICATION APPEARS UNLIKELY AS THE STORM
IS EXPECTED TO REMAIN OVER MARGINALLY WARM WATERS AND IN A FAIRLY
STABLE AIRMASS. THE DUST PRODUCT IMAGERY FROM THE GOES-R PROVING
GROUND SHOWS SOME DRY AIR WRAPPING AROUND THE PERIPHERY OF THE
CIRCULATION...AND GFS AND ECMWF MODEL VERTICAL CROSS SECTIONS
SUGGEST THAT THIS DRY AIR WILL CONTINUE TO AFFECT THE STORM DURING
THE NEXT SEVERAL DAYS. THE SHIPS MODEL SHOWS A SUBSTANTIAL INCREASE
IN WESTERLY SHEAR BY TUESDAY...AT WHICH TIME STEADY WEAKENING IS
ANTICIPATED. THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ONE
AND SHOWS A SLIGHT INCREASE IN STRENGTH FOR THE NEXT DAY OR
TWO...FOLLOWED BY STEADY WEAKENING DUE TO THE AFOREMENTIONED
INCREASE IN SHEAR.
THE CYCLONE HAS BEEN ON A STEADY WEST-NORTHWESTWARD PATH AT ABOUT 13
KT FOR THE PAST 24 HOURS. THE DYNAMICAL MODELS INSIST THAT FLORENCE
WILL BEND TO THE WEST DURING THE NEXT FEW DAYS AS A LOW- TO
MID-LEVEL RIDGE BUILDS WESTWARD TO THE NORTH OF THE TROPICAL STORM.
THE LATEST GUIDANCE HAS SHIFTED SOUTHWARD...AND THE OFFICIAL
FORECAST HAS BEEN NUDGED IN THAT DIRECTION. HOWEVER...THE NHC
FORECAST LIES ON THE NORTHERN SIDE OF THE GUIDANCE ENVELOPE AS MOST
OF THE MODELS HAVE SHOWN A SOUTHWARD TRACK BIAS UP TO THIS POINT.

The current forecast track from the NHC
Early Cycle Track Guidance
Currently, there is no threat to land. It is possible, based on long range forecast models, Bermuda may have some impacts from this system down the road. Plenty of time to watch this one. Fish for now......
SEVERE WEATHER THREAT
A powerful Upper Shortwave Trough and cold front, sweeping into hot, humid air in the East, will trigger Severe Storms one again while extreme heat continues for the Central Plains.
The Ohio Valley and eastern Great Lakes are waking up to the sound of thunder this morning. The Cold front that is producing these storms will continue it's Eastward march throughout the day. This is the same storm system which we discussed a few days ago that brought severe weather from the Dakotas to the western Great Lakes Friday and Saturday. All the necessary atmospheric ingredients will come together today to help trigger potentially dangerous thunderstorms. People can expect Lines of dangerous thunderstorms producing damaging winds in excess of 60 mph as well as torrential downpours. Hail to the size of pin-pong balls will also be possible, especially from the Ohio Valley south into the middle Mississippi Valley. An isolated tornado or two cannot be completely ruled out at this point. As was the case with last weeks storms, millions of people will be affected by these possible Severe Storms today.
Several sporting events may also be impacted including the Pennsylvania 400 Sprint cup race in Pocono, Pennsylvania and the final round of the WGC Bridgestone Invitational being played at Firestone Country Club in Akron, Ohio. The NFL Pre-season football games should not be affected.
Here is the SPC's Convective Outlook for today.

Nice blog..and your thoughts on the TUTT in the Gulf??/Could it keep moving WNW and combine with that shortwave trough ?? If so that would change everything as it may be what attracts Ernesto North..

Well Gomey as you know we have been discussing from the get go that Ernesto's future track will an intensity based forecast, meaning depending on how strong he gets will determine where he makes landfall. This TUTT feature in the GOM is one of the key factors of this intensification process as it was expected to move SW and create excellent environmental conditions ahead of Ernesto in a couple of days. This has been discussed on may of forums , blogs, and YouTube postings by both amateur and professions Meteorologist. With that being said.
The Strong Short Wave Trough, for early August standards, is moving through the Ohio River and Tennessee River Valleys as was discussed in detail above. This is the first trough that was to move through the area and begin to weaken the ridge. Here is a look at the trough.
The TUTT feature in the GOM looks to be moving in a WNW direction towards the coast line. One would have to think the these features would have to have an effect on each other. I would have to think that if the TUTT continues to move to the WNW, it would change every thing that the Global Models are currently looking at. Maybe this is why the Tropical Models are shifting the tract to the NW somewhat. Maybe this is why this model continues to move Ernesto more Northward.

I have never known a woman to be named Ernesto. If there is one, I would not want to scrap with her. Just sayin.

From Levi's FB
Ernesto now an open wave undeserving of its name. We expected this as a possibility. Ernesto is not dead though. The pressure center is still 1006mb, and most of the trade winds are behind it now. This is a very vigorous tropical wave that I have said should be treated as a healthy tropical disturbance until the western Caribbean where it may truly develop. The question is how fast it will regenerate before running into the Yucatan. A hurricane is still possible, but the longer it hesitates, the better news for Central America.

Nice little burst of convection around the other wise naked COC of Ernesto.
We shall see if it can somehow wrap around the center.

IMO Ernie's showing a little sign of life now but I have no clue if it's temporary or maybe he wants to try getting his groove on. Nonetheless he's still chugging along due W and, if that continues, Honduras it may be.

TROPICAL STORM ERNESTO DISCUSSION NUMBER 19
NWS NATIONAL HURRICANE CENTER MIAMI FL AL052012
500 AM EDT MON AUG 06 2012
DEEP CONVECTION CONTINUES TO BURST NEAR AND TO THE EAST OF THE
ESTIMATED CENTER LOCATION OF ERNESTO. HOWEVER...THE CLOUD PATTERN
HAS NOT CHANGED MUCH IN OVERALL ORGANIZATION IN THE PAST FEW HOURS.
THE INITIAL INTENSITY REMAINS 45 KT IN AGREEMENT WITH THE LATEST
DVORAK ESTIMATE FROM TAFB. SATELLITE IMAGERY AND GLOBAL MODEL
ANALYSIS FIELDS SUGGEST THAT THE VORTEX CONTINUES TO BE TILTED
NORTHEASTWARD WITH HEIGHT...AND THIS STRUCTURE SHOULD ONLY ALLOW
FOR GRADUAL STRENGTHENING IN THE SHORT TERM. THE SHIPS AND LGEM
MODELS STILL SHOW ERNESTO APPROACHING HURRICANE INTENSITY IN 36 TO
48 HOURS...AND THAT IS POSSIBLE EVEN THOUGH IT IS NOT SHOWN
EXPLICITLY IN THE OFFICIAL FORECAST. LATER IN THE PERIOD SOME
RE-INTENSIFICATION IS SHOWN AFTER THE CENTER MOVES OVER THE EXTREME
SOUTHERN GULF OF MEXICO. THE NHC FORECAST IS CLOSE TO A BLEND OF TH
DECAY SHIPS AND LGEM THROUGH THE PERIOD.
THE CENTER OF ERNESTO HAS BEEN DIFFICULT TO LOCATE OVERNIGHT USING
GEOSTATIONARY IMAGERY. THEREFORE THE ESTIMATED CENTER LOCATION
NEAR WESTERN EDGE OF THE DEEP CONVECTION IS BASED ON A BLEND OF
SATELLITE FIXES AND CONTINUITY. THE INITIAL MOTION APPEARS TO HAVE
SLOWED FURTHER...WITH A LONG-TERM ESTIMATE OF 275/10. THE OVERALL
SYNOPTIC REASONING FOR THE TRACK FORECAST REMAINS UNCHANGED...AS
ERNESTO IS EXPECTED TO TURN WEST-NORTHWESTWARD IN THE NEXT DAY OR SO
AS A WEAKNESS DEVELOPS IN THE SUBTROPICAL RIDGE OVER THE EASTERN
GULF OF MEXICO. THIS WEST-NORTHWESTWARD MOTION IS EXPECTED TO
CONTINUE AS THE CENTER OF ERNESTO MOVES ACROSS THE YUCATAN
PENINSULA AND EMERGES INTO THE SOUTHERN GULF OF MEXICO IN ABOUT 72
HOURS. AFTER THAT TIME A TURN BACK TOWARD THE WEST IS SHOWN BY MOST
OF THE GUIDANCE. OVERALL THE GUIDANCE ENVELOPE HAS SHIFTED A LITTLE
SOUTHWARD THIS CYCLE. THE NHC FORECAST HAS BEEN ADJUSTED IN THAT
DIRECTION BUT IS STILL A LITTLE NORTH OF THE TVCA CONSENSUS.
BASED ON THE LATEST NHC TRACK FORECAST...NEW WATCHES AND WARNINGS
HAVE BEEN ISSUED FOR THE COAST OF HONDURAS AND PORTIONS OF THE EAST
COAST OF THE YUCATAN PENINSULA OF MEXICO.
