Dr. Jeff Masters' WunderBlog

Beneficial Barry
Posted by: Dr. Jeff Masters, 04:43 PM GMT am 03. Juni 2007 +3
Tropical Storm Barry is no more. Its remnants, now an extratropical storm with top winds of 40 mph over the ocean, are over the Mid-Atlantic coast, moving north-northeastward at 10 mph. Barry's remnants are expected to bring 1-3 inches of rain along the Mid-Atlantic and New England states through Monday. Was Barry really a tropical storm? I think it should have been named "Subtropical Storm Barry", and I hope NHC looks at the storm carefully to consider redesignating it after the season is over. Read Margie Kieper's View From the Surface blog for more on this.

On Saturday, Barry brought up to seven inches of rain to drought-parched Florida, including an official 6.99" to West Palm Beach, 4.07" to Jacksonville, 5.91" to Savannah Georgia, and 3.17" to Tampa. Barry's rains probably provided tens of millions of dollars of benefit--quite the opposite of what we're used to saying about tropical storms! The fire area near the Florida-Georgia border got between 1-5 inches of rain from Barry, which has dampened but not extinguished the fires. Barry's rains also helped a bit with the Florida drought. However, Barry's rains were only 1-2 inches over central Florida, and they need about 30 inches of rain to pull them out of drought conditions. The summer rainy season typically begins in June, so there is hope that substantial rains are on the way. There doesn't appear to be much rain coming this week, though.

June outlook
My outlook for the first two weeks of June was posted Friday. I don't see anything on the horizon for the remainder of this week--wind shear is expected to be high most of this week over the favored breeding grounds for June storms--the Gulf of Mexico and Western Caribbean. Wind shear may drop enough over the Western Caribbean early next week to allow tropical storm formation, but that is too far in the future to guess at the probability of such an event.

This will be my last "live" blog until Monday June 11; it's time to grab a week of summer vacation while the tropics are quiet. I'm off to see Niagara Falls and the "Grand Canyon of the East", New York's awesome Letchworth State Park. I hope to get some good waterfall rainbow shots to add to my wunderphotos. I've written two canned blogs that will be posted Tuesday and Friday while I'm gone:

Tuesday--We've all used NHC's Tropical Weather Outlook, which most often this time of year says, "Tropical cyclone formation is not expected during the next 48 hours." How accurate are these outlooks? I'll present some verification statistics from 2005 and 2006.

Friday--The NHC made it's best track forecasts ever last year. How good are their forecasts now? Which of the various computer models performed the best last year? I'll have a breakdown of the numbers.

Arrogance
Our Climate Change blog by Dr. Ricky Rood has an interesting commentary on what the chief of NASA said last week in an NPR interview when asked, "Do you have any doubt that climate change is a problem that mankind has to wrestle with?"

Strongest tropical cyclone ever seen in Arabian Sea
Follow The View From the Surface blog this week to track Tropical Cyclone Gonu. Gonu is the strongest storm ever seen in the Arabian Sea, and could cause big trouble for the Persian Gulf oil rigs and tankers.

Hmm... That wave does look healthy. However, I think that it is beginning to dissipate. Notice the outflow? I think that is a sign of dying Thunderstorms. Either that or It'll be a cat 3 tomorrow.

I think your correct about the thunderstorms. If this was a tropical system than outflow would mean organization.

Looking at the radar, I guess it's not just limited to supercells.

Tropical Storm Allison's low-level circulation dissipated, though the mid-level circulation persisted. It emerged into the Gulf of Mexico on the 4th, and developed deep convection on its eastern side. On June 5, the mid-level circulation extended to the surface, and organized into Tropical Storm Allison while just 140 miles (225 km) to the south of Galveston, Texas.

WPB- If I am remembering correctly, Allison killed many people in Texas and gave several major cities Major Flooding. Over a foot and a half of rain in some parts, correct?

Right. :)

Anyone got any surface maps they could link? I'm curious about wheather or not that is an actual wave or just a large thunderstorm complex.

Or, could anyone explain to me how to tell if it is a wave via Satalite?

Yup. Mainly because Allison stalled over Houston and Houston is flat. Stalled Tropical Storm + Flat Land = BIG PROBLEM.

I'm just thinking what kind of rain that might bring if it was moving out 8 or 10 weeks from now . . .

Good thing it's just June.

T2- It's really not worth the argument, so just save your fingers. It doesn't matter whether you're right or wrong.. The NHC called it Tropical, They are the Officials, and that's what it is. You can't change it. It's a futile argument if you continue to stake a claim to the contrary. I'm just being blunt with you T2, so please don't take this personally. It's not meant in a hostile way.

WPB- That's what I thought.. Houston was gridlocked for days because of floods and there was something like 2-3 million people attempting to navigate elsewhere.. Crazy. Imagine a Major Hurricane hitting Houston.. :O

BTW- Don't forget tonight at 9pm.. TWC Showing "It could happen Tomorrow" Major Hurricane Making Landfall in Downtown Miami. Gulp.

I'm just trying to tell you from experience, we were arguing yesterday for an hour and there was really no point.. Lol. I'm just trying to help you out, because the blog is a good place until it turns into a war zone. Now, If there was a Cat4 Hurricane barreling towards the U.S. Someplace... This Blog would be insanely packed with arguments, that's when most people turn to other blogs or forums where there is more control over the users and more stability in the discussions. :/
That's one of the reasons I made my forums..

283. louisianaboy444 09:33 PM GMT am 03. Juni 2007    
Shear is probably going to be too high for the next 10 days

Louisianaboy- There is no forecast on Wind Shear outside of 120 hours.. Winds are difficult to forecast outside of a few days, let alone 10 days, What do you base your prediction on?


By the way, I've posted a new blog entry, please feel free to read it!! Thanks!
