The Atlantic is quiet; Russian heat wave ends; huge 926 mb South Indian Ocean storm

A tropical wave in the western Caribbean approaching Mexico's Yucatan Peninsula is generating disorganized thunderstorms. Wind shear is a moderate 10 - 15 knots over the region, and water vapor satellite images show that there is some dry air to the west that will interfere with any development that might occur. None of the reliable computer models develop this wave, and NHC is giving it a 10% chance of developing into a tropical depression.

The GFS, NOGAPS, and ECMWF models continue to predict that a tropical storm will form between Africa and the Lesser Antilles Islands sometime in the period 3 - 6 days from now. There is an area of disturbed weather south of the Cape Verdes Islands, but there is no obvious organization to the cloud pattern. Wind shear is a hefty 20 - 30 knots in the region, and the disturbance is a 1 - 2 day journey away from reaching a lower shear area where development can occur. Preliminary indications are that if a storm did develop in this region, it would track west-northwest and pass well to the northeast of the Lesser Antilles Islands 7 - 8 days from now. However, 7-day forecasts of a storm that hasn't even formed yet are not to be trusted.

The Great Russian Heat Wave of 2010 ends
A powerful cold front swept through Russia yesterday and today, finally bringing an end to the Great Russian Heat Wave of 2010. Temperatures at Moscow's Domodedovo airport hit 25°C (77°F) today, which is still 4°C (7°F) above average, but the high temperature since late June. Moscow has seen 62 consecutive days with a high temperature above average, but the latest forecast for Moscow predicts that remarkable string will come to an end Friday, when the high will reach just 17°C (62°F).

Massive 926 mb extratropical storm generating huge waves off Antarctica
One of the most intense extratropical storms in recent years is churning up the waters near the coast of Antarctica in the South Indian Ocean. The powerful storm peaked in intensity yesterday afternoon with a central pressure of 926 mb--the type of pressure typically found in a Category 4 hurricane. Storms this intense form on average once per year, or perhaps less often, according to an email I received from Jeff Callaghan of the Australia Bureau of Meteorology. Since extratropical storms do not form eyewalls, the winds at the surface from this monster storm probably reached "only" 100 - 120 mph (equivalent to a Category 2 or 3 hurricane.) The storm is forecast to generate huge waves with a significant wave height of 13 meters (44 feet) today, according to the NOAA Wavewatch III model (Figure 3.) I have flown into an extratropical storm this intense--in 1989, I participated in a field project based in Maine that intercepted a remarkable extratropical storm that "bombed" into a 928 mb low south of the Canadian Maritime provinces. You can read my story of that somewhat harrowing flight here.

Figure 5. Predicted wave height from the NOAA Wavewatch III model for 2pm EDT (18 UTC) today, August 19, 2010. Peak wave heights of 13 meters (44 feet) are projected over ocean areas between Antarctica and Australia. Long-period waves (19 seconds between crests) up to 7 meters (22 feet) high are predicted to affect the southwest coast of Australia by Sunday. The waves are predicted to propagate eastwards to New Zealand 8 - 9 days from now, and be a respectable 4 - 5 meters high then.

I think that the intensity has to do with the eventual path. The GFS intensifies it the most, keep that in mind. The CMC keeps it more weak, and on a more WNW track.

This is my explanation of the NAO, please feel free to correct anything that way I don't look like a fool when I post it, LOL.

"When the NAO is negative the subtropical ridge is weaker and further to the SE. When the NAO is negative as I said, there is ridging over the eastern and western portion of the North Atlantic, additionally you have the subtropical ridge spread out over the subtropical Atlantic. As you know, these ridges happen to displace the middle tropospheric trough of lower pressures to the north. This trough, which happens to induce hurricane movement to the northeast, is therefore unable to recurve hurricanes that are moving westward toward the United States thus increasing the probability of landfalls along the Gulf and southeast coasts. When you have a positive NAO, yes the subtropical ridge is stronger, but the middle tropospheric trough of lower pressures is not going to bet pushed northward because there is no ridging to do so. So guess what happens? That trough is going to pick up a tropical cyclone moving towards the U.S, that would rarely happen in a negative NAO."

What? Why would an anticyclone, an upper level feature, force a system that's being steered by the 850 to 500 mb flow, west?

1. Better with the full stops=easier to read.... mucho Ta very much... lol

2. Pretty much u r saying what StormW was referencing earlier... Between the 2 of u, we get a fairly clear picture of why a recurve prior to 60 W is not as likely as models would have us believe...

Thanks for the input.

Trends on satellite imagery favor a slowly developing future tropical cyclone as wave develops further low level cyclonic circulation and 850mb vorticity pools into the region. Currently circulation appears to be located near 27w and 12-13n. Convection is consolidating over this low and equatorward outflow channel is developing towards the ITCZ. Wave does appear to be trying to get away from the ITCZ at this time. Wind shear is still a little high on the southern side of the system which may be because of potential upper level anticyclones battling against each other.

So now where does it go?

Models are hell bent on the cyclone going way out into the Atlantic Ocean graveyard as a potential major hurricane. However I beg to differ on how far east they are showing it recurve. Now we all know this system will recurve, but where and when will this happen is the ultimate question asked. So with no further ado, here is my reasoning: -NAO currently bottoming out, and slowly rebounding towards neutral and then positive levels as it nears the 14 day forecast. So what does this mean? It means that the A/B high has peaked at its most weakest point now, and that it will slowly begin to respond and be quite strong by day 14. Now if this is true then why are the models too far out to sea with the system? Answer is I don't know why.

Why? Well we have a +PNA trending neutral to negative which means the ridge over the western CONUS is quite strong today will continue to deamplify and the trough downstream will do the same. Now the models show a shortwave closing off at 500mb as a cutoff low develops next week as a strong ridge builds over the NE CONUS and Maritimes of Canada do to the building heights on the models. Now this was from a few days ago, today however the models trended towards a strong -NAO pattern with a strong Greenland blocking ridge in place and a 50/50 low over and near Labador, Canada. This 50/50 low or 50n/50w latitude/longitude low pressure center is associated with a modeled highly amplified trough which digs seward towards the hurricane the models develop. This trough forces a weakness within the A/B high and extension of the eastern US high as the PNA ridge deamplifies and allows a western US trough to come through or rather zonal flow at 500mb. Now the difference is that the models amplify the trough because the ridge downstream becomes amplified. Now I think the opposite occurs with a rather strong zonal flow developing allows the trough to shear out and weaken rather then strengthen. So this trough shears out and the A/B high strengthens as the models have the NAO index back to positive by day 14 and our hurricane nears 70w/25n. With that in mind it sounds like I expect perhaps a major hurricane in a threatening position SW of Bermuda. Right now that are my thoughts on the models vs reality debate. I hope you enjoyed them.

Tropical Cyclone Outlook
0:00 AM UTC August 20 2010
=======================================

An area of disturbed weather has formed about 175 miles southwest of Manzanillo, Mexico. Some additional development of this system is possible during the next day or two before it moves westward over cooler waters.

Tropical Cyclone Formation Potential
======================================
There is a LOW chance of this disturbance to form into a tropical cyclone within the next 48 hours
