Dude! It's almost as far south as me.

There is much more mercury in fish than there is in CFL bulbs. And there will still be incandescent bulbs after 2012. Two more rumors/exaggerations that just refuse to die.
Mainly because the ground is so dry it heats up much more easily therefore showing up pink on infared
That is going to Modify as the Heat in the GOM and the flow off Texas alone is gonna pucker that air up fast.
Plus the inflow of the developing pouch is insulated from the Dry air.
Nutting gets past you Rita.
Thanx for the Color.
Where do you feel that the dry air going to go (or, what is it going to do?) It's quite massive.
Sounds good to me...I've had two fires within 5 miles of my house...hell, I admit it, I'm rooting for any kind of rainmaker right now.

Short term...

wow...is the only word that comes to mind as we have quickly moved
from a tropical wet mess to cool dry air that is making things
very comfortable. This air mass hangs around for several days. Highs
will struggle getting into the lower 80s today and Wednesday. As we all
know...sept can be just as hot as August. But this is a much
needed break from the heat and humidity. A slow warming trend will
take temperatures into the upper 80s again by the weekend and back to the
90s by next week.
At some point we will have to acknowledge that another tropical
system will be forming in the southern Gulf. This area is
currently very unsettled and has the very southern end of a
stalled cold front. All the ingredients are there for a disturbance
to develop. The question is not if...but instead...once it does
where does it go? Something should be showing up as early as Wednesday.
After it develops...a slow drift to the north should ensue Thursday and
Friday. This is where confidence begins to lower. The portfolio of
global models are somewhat different in their solutions with the
Euro taking the system near Pensacola by Sunday and the GFS taking
it into Mexico. All models bring a strong short wave around the
large scale upper low over the Ohio Valley causing a strong trough
to once again dig and move southward. This is the weakness that
most other guidance packs are showing breaking the ridge and
pulling the system northward into the Gulf Coast. The interesting
thing is that the GFS also shows this same weakness in the upper
level pattern but builds the middle level ridge between the upper
trough and the disturbance cutting off its northward progress.
The reason for the models difference in placement of the system is
timing. The GFS develops the system more slowly before moving it
northward and therefore gives the Bermuda ridge time to develop
back westward behind Katia and into the Gulf. The Euro develops it
quicker and starts its northward journey sooner so that when the
Bermuda ridge builds west it is too late. So as usual...timing
will play a significant role in where this one ends up. The
shorter the time the disturbance starts moving north...the more
bets will be on a Euro solution. A little later and the GFS wins.
Even later and none will get it right as the system would get
pushed toward the SW into central Mexico.
That's fine--but just remember that every time you minus a post, you drive down both that commenter's "karma" and your own, as well.
I did forget that though I don't think it'd be 30%; I won't hazard a guess at the actual percentage though since it depends on how large the tax itself is (the collection/disbursement costs should stay constant so the higher the carbon tax is, the lower the percentage that would go to c/d).
Am I on your ignore list? Your not on mine.
1st night since Late March i have been able to sit and watch tv without wearing a jumper. Now
55.9°F and 1.8mm of rain since 9am yesterday Morning. Current time, 03:45 Wednesday 7th of September.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 PM EDT TUE SEP 6 2011
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON HURRICANE
KATIA...LOCATED ABOUT 365 MILES SOUTH-SOUTHWEST OF BERMUDA.
SATELLITE IMAGES INDICATE THAT A TROPICAL DEPRESSION COULD BE
FORMING ABOUT 725 MILES WEST-SOUTHWEST OF THE CAPE VERDE ISLANDS...
AND IF THIS TREND CONTINUES...ADVISORIES WILL BE INITIATED LATER
TODAY. THIS SYSTEM IS EXPECTED TO MOVE TOWARD THE WEST OR
WEST-NORTHWEST AT ABOUT 15 MPH AND HAS A HIGH CHANCE...90
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
A LARGE AREA OF DISTURBED WEATHER OVER THE SOUTHERN GULF OF MEXICO
IS BEGINNING TO SHOW SOME SIGNS OF ORGANIZATION...BUT ANY
ADDITIONAL DEVELOPMENT IS ANTICIPATED TO BE SLOW. AN AIR FORCE
PLANE IS SCHEDULED TO INVESTIGATE THIS AREA ON WEDNESDAY...IF
NECESSARY. THIS SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
A TROPICAL WAVE LOCATED ABOUT 500 MILES EAST OF THE LEEWARD ISLANDS
IS EXPECTED TO MOVE WESTWARD AND BRING CLOUDINESS AND SHOWERS OVER
THESE ISLANDS DURING THE NEXT DAY OR SO. UPPER-LEVEL WINDS ARE NOT
FAVORABLE FOR SIGNIFICANT DEVELOPMENT...AND THIS SYSTEM HAS A LOW
CHANCE...10 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.
ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

I will take my chances..
There has been some talk of that here at the office. Lots of dry air to push through, and we remember how that dry air affected Lee. Lee was able to hold his own, but was kept from strengthening much and rain bands ended up more broken and spotty. Now with substantially more dry air - deep dry air - in the Gulf of Mexico, I think it will take some time for a system to get going.
After all the rain we just had, think that will be a good thing.

It's simply that the air is so dry that it has fallen off the lower end of the water vapor enhancement color scale. I've seen it once before, but not quite as large as it was yesterday.
Levi, which model run will we see the new data from the HH?
the corollary would be hitting plus a bunch of times would improve your karma...
Back to the weather and off the political...
It's the Dry Air of Doom
