Colin takes aim at Bermuda; the Great Russian Heat Wave of 2010: 102°F in Moscow
A reborn Tropical Storm Colin is taking aim at Bermuda, and should bring tropical storm force winds to the island by Saturday afternoon. Colin continues to pass through an unfavorable environment for development--an upper-level low pressure system with dry air and high wind shear. High wind shear of 20 - 25 knots has exposed the surface circulation to view, as seen in recent satellite imagery. Colin's heavy thunderstorm activity is all on the east side of the storm, and the associated rains can now be seen approaching the island on Bermuda radar.
Forecast for Colin
The latest SHIPS model forecast predicts that wind shear will drop to the low to moderate range, 5 - 15 knots, tonight through Saturday afternoon. This relaxation of shear prompts the intensity models to predict that Colin will strengthen to a 50 - 70 mph tropical storm by Sunday. With the forecast path of the storm predicted to take Colin just west of Bermuda, the island will be in the strong right front quadrant of the storm, and may see wind gusts in excess of hurricane force, 74 mph. After its encounter with Bermuda, Colin will head towards Newfoundland, and it is possible the storm could bring tropical storm force winds to the island on Monday. However, wind shear will be on the increase again beginning Saturday night, and it is unlikely Colin will be a hurricane when it makes it closest approach to Newfoundland.

93L
A tropical wave (Invest 93) about 700 miles west of the Cape Verdes Islands off the coast of Africa is moving northwest at 10 mph. Wind shear is a moderate 10 - 20 knots over 93L, which is low enough to allow some slow development. This system currently does not appear to be a concern to any land areas over the next seven days. NHC is giving a 40% chance of this disturbance developing into a tropical depression by Sunday morning. The GFS and NOGAPS models predict 93L will become a tropical depression.

Visibility in Moscow dropped to 20 meters (0.01 miles) on August 4, and health officials warned that everyone, including healthy people, needed to take preventative measures such as staying indoors or wearing a mask outdoors.

The Great Russian Heat Wave of 2010 continues
One of the most remarkable weather events of my lifetime is unfolding this summer in Russia, where an unprecedented heat wave has brought another day of 102°F heat to the nation's capital. At 3:30 pm local time today, the mercury hit 39°C (102.2°F) at Moscow's Domodedovo Airport. Moscow had never recorded a temperature exceeding 100°F prior to this year, and today marks the second time the city has beaten the 100°F mark. The first time was on July 29, when the Moscow observatory recorded 100.8°C and Baltschug, another official downtown Moscow weather site, hit an astonishing 102.2°F (39.0°C). Prior to this year, the hottest temperature in Moscow's history was 37.2°C (99°F), set in August 1920. The Moscow Observatory has now matched or exceeded this 1920 all-time record five times in the past eleven days, including today. The 2010 average July temperature in Moscow was 7.8°C (14°F) above normal, smashing the previous record for hottest July, set in 1938 (5.3°C above normal.) July 2010 also set the record for most July days in excess of 30°C--twenty-two. The previous record was 13 such days, set in July 1972. The past 24 days in a row have exceeded 30°C in Moscow, and there is no relief in sight--the latest forecast for Moscow calls for high temperatures near 100°F (37.8°C) for the next seven days. It is stunning to me that the country whose famous winters stopped the armies of Napoleon and Hitler is experiencing day after day of heat near 100°F, with no end in sight.
Thousands of deaths, severe fires, and the threat of radioactive contamination
The extreme heat has led to thousands of premature deaths in Russia. According to Yevgenia Smirnova, an official from the Moscow registry office, "We recorded 14,340 deaths in Moscow in July, that is 4,824 deaths more than in July, 2009." Undoubtedly thousands of additional premature deaths have occurred in the rest of Russia as a result of the heat. The heat has also caused the worst drought conditions in European Russia in a half-century, prompting the Russian government to suspend wheat exports. The drought has caused extreme fire danger over most of European Russia (Figure 3), and fires in Russia have killed at least 50 people in the past week and leveled thousands of homes. The fires are the worst since 1972, when massive forest and peat bog fires burned an area of 100,000 square km and killed at 104 people in the Moscow region alone. Smoke from the current fires spans a region over 3,000 km (1,860 miles) from east to west, approximately the distance from San Francisco to Chicago. Dozens of flights were canceled at Moscow's airports today, thanks to visibilities of 300 meters in smoke. Also of concern is fires that have hit the Bryansk region of western Russia, which suffered radioactive contamination from the Chernobyl nuclear disaster in nearby Ukraine. There are fears that fires may burn through the contaminated area, releasing harmful radiation into the atmosphere.

Why has Russia's heat wave been so long and intense?
Dr. Rob Carver has done a detailed analysis of the remarkable Russian heat wave in his latest post, The Great Russian Heat Wave of July 2010. A persistent jet stream pattern has set up over Europe, thanks to a phenomena known as blocking. A ridge of high pressure has remained anchored over Russia, and the hot and dry conditions have created helped intensify this ridge in a positive feedback loop. As a result, soil moisture in some portions of European Russia has dropped to levels one would expect only once every 500 years.

I'll have an update on Saturday morning.

Bryan's good in my book. I was hunkered down in my house back in 1992 watching Andrew spin across the Bahamas and toward me and my two very young children while watching Norcross on the TV. At one point, he said some of the most chilling words I've ever heard: "Absolutely, there is no doubt about it, it is going to happen tonight". I thought I'd killed my family. Anyway, I stayed with him until the power went out, so I've always been a bit grateful...
Andrew was a small compact storm and NHC was not in the core of that storm where they were located in 1992....They were on US 1 just south of UM and north of where the core came accross (but they did lose their doppler dome from the top of the building).....The current location of NHC is further south but not quite where the core of Andrew was either.
The NWS Storm Prediction Center has issued a

It just seemed to have broadened-out a bit on last few frames.
Convection may swallow it up soon, the way its going.
Thats been our saying in the islands for the last 3 days..

Funny, the watch excludes most of the best looking convection. :)
Ah, a VERTICAL balance, rather than a horizontal one.... so the heat is not being taken from the tropics to the poles so much as from the bottom to the top...
Thanks, Karen.
lol, about 30 sec - 60 sec.
Ref to 292: Simply put, (and that is the only way I can put it) it is an interesting blob to watch. There is convergence at the lower levels, and divergence at the upper levels that is causing, along with some vorticity nearby, which is causing the convection to build over the area...
All of which are ingredients that are needed for the start of any possible TC development.
(Then again, I did sleep at a Holiday Inn Express last night!!!)
Ah cool more recoon reports. coming.
There still happening everywhere, but no one is paying close attention like a couple of months ago.
Yeah....My girfriends house was in the core and was leveled by the time I got back there on Monday morning after the storm passed......We luckily decided to stay with our parents further north in Miami after we borded it up on Sunday afternoon......Lost everything we had at the time (except for our cars).

Ok I have to know what the heck that joke is lol? I've seen it posted 5 times a day for the last week and I have no idea where it came from.
Colin IS far from dead.

You don't have Holiday Inn Expresses up there?
It's from an ad campaign whereby people talk authoritatively about something or perform surgeries etc., only to have people around them find out they don't have qualifications but did stay at a Holiday Inn Express the previous night, the implication being that that decision makes you smart.

While this is not yet at all the kind of pattern that I think we are going to get to this season, some of the naysayers out there should understand that their fears of the non-season seemed to be based less on fact than superstition. If you look at the picture above, you can easily see why... in a NEUTRAL pattern for development, three systems are trying to develop, one already named, one about to run out of room, and one that will be the season's next named storm, in my opinion, but remains out at sea.
That this is "suddenly" occuring now is no surprise, as I forecast last week we would get a name this week. However, you have to understand that this pattern now is not really anything special for development, and is not what I am thinking is coming... Yet from next to nothing a week ago, to three nicely shaped systems, should tell you how fast things can go pop.
The GFS still is not picking up what I think could be the next threat to the U.S., and that is what this front may do once down in the Gulf and off the southern Atlantic coast. It's trying... but it's not yet to where the Euro is on it. An interesting situation, and the reason I am concerned about this is that it fits a pattern that can lead to this kind of non-deep tropical development, and on top of someone.
By the way, the loop of the above still is pretty interesting... take a look...
http://www.ssd.noaa.gov/goes/east/tatl/flash-vis.html
Colin should start to intensify tonight and tomorrow as the low-level center is being pulled under the mid-level system, and that is usually an invitation to deepen.
The big news, though, is the heat, which will reach high tide next week in the Ohio Valley, which though hot this summer, has been spared the worst of the summer heat. They will have their turn next week.
Thanks for reading, ciao for now. *****
