The Atlantic is quiet; Pakistan monsoon rains continue; last day of Russian heat wave
A tropical wave in the Caribbean near Jamaica is generating disorganized thunderstorm activity over the central Caribbean. Wind shear is a moderate 10 - 20 knots over the region, and water vapor satellite images show that there is some dry air to the west of Jamaica that will interfere with any development that might occur. None of the reliable computer models develop this wave.
The GFS, NOGAPS, and ECMWF continue to predict that a tropical storm will form between Africa and the Lesser Antilles Islands 3 - 7 days from now. A strong tropical wave currently moving off the coast of Africa is a good candidate for such a development. The NOGAPS model is predicting the development of a strong tropical disturbance near the coast of Honduras this weekend.

Figure 1. Extreme flooding along the Indus River in Pakistan has swollen the river to 16 miles (24 km) wide in sections, as seen in the top image from yesterday. For comparison, and image taken a year ago at this time in August (bottom image) shows that the Indus is normally just 1 - 2 km wide during monsoon season.

Extreme flooding and monsoon rains continue in Pakistan
In flood-ravaged Pakistan, heavy monsoon rains hit the Punjab region in the northeastern portion of the country yesterday, dropping up to 113 mm (4.45") of precipitation. The main river in Pakistan, the Indus, continues to cause extreme flooding, and has expanded to 16 miles (24 km) wide in some sections (Figure 1.) Dr. Ricky Rood, who writes our Climate Change Blog, has a sister that works in Pakistan. He has a must-read analysis of the catastrophe in Pakistan, "Pakistan: A Climate Disaster Case Study".
Moscow hits 93°F on the final day of the Great Russia Heat Wave of 2010
Temperatures at Moscow's Domodedovo airport hit 34°C (93°F) today, which is 13°C (22°F) above average. However, pressures are falling rapidly and winds are picking up out ouf the southwest in advance of a powerful cold front that promises to sweep through all of European Russia tonight, finally bringing an end to the Great Russian Heat Wave of 2010. The latest forecast for Moscow predicts Thursday's high will be just 21°C (69°F)--essentially average. With tonight's cold front will come rain to help put out the fires that continue to plague Russia with toxic smoke. Cool temperatures near of below average over the coming week will also help fire-fighting efforts.

He was talking about the cool dry autumnal air moving into the NE, not the CV storm that hasn't even formed yet.
Thank you :)
Fall is going out to sea. lol Is the ocean going to change colors.
When I look at long range model forecasts, I first look for the development then the latitude..the timing isn't there at 120 hrs +
due to unforeseen influences (like the NE shear on ex-5 that wasn't even seen 24-48 hrs out!)
I'm sure its a long way out.
Well stated Levi!
Yes, indeed.... <_<
Your post should have an edit button on it to go back and fix it. Or you could turn it into a blog entry :)

Well, it's still raining in La
True. Even the NHC's "cone of doom" has a margin of error at 5 days out.
And that's AFTER a storm has formed...
Careful! You're giving away too many tricks of the trade there!
Looks like it's starting to turn more WNW to NW on the end of the run.
Reach out with your feelings. Use the force...
Probably a TD heading for a TS by then.
But I guess some just can't resist the urge to label something before its formed; to me that shows a lack of knowledge. Some of those same people bash others for counting on long range models and yet they do the same thing; they call it a fish because the models hint at it.
Another Leo? I started my next trip around the sun today.
He said severe cold, not cold.
