"My next post will be sometime Monday afternoon/evening."
good show
Ty...phew.
I was a bit pekid..
Best time to be on here is early morning....5-9 am.
Anyway I didn't think much of Alex and felt there was little chance of it coming here to Texas, perhaps Brownsville at best, but I had my doubts since it was crossing pretty far over the Yucatan and there is a general trend of storms like that moving into Mexico. Alex was of course no exception.
Invest 96L, is quite a different matter! This is a serious threat to Galveston amd Houston. It is worth looking at a recent study by Rice University about how a Hurricane right now would cause devastating damage to Houston.
I won't blow my own trumpet, but as a keen weather amateur, I called Ike exactly, when others didn't. Houston TV weathermen shamefully got it wrong right up to the day it struck. OK too early too say, but I think this is a big threat to the city of Galveston.
I note that 5 of the spaghetti tracks take it close to Galveston and the Houston ship channel, which would pose a considerable flooding threat to the city. One other points to about Corpus Christi, and the last into Mexico. If this thing only clips the Yucatan as I suspect, I doubt it will go to Mexico. Watch out Texas!
I've noticed. Still, ya'll have an awesome blog here and I truly enjoy it.
nuthin but zombies and crybabies
they will "nest"...scratch in the same area, pace in a circle, then "settle in"
target aguired
lockon confirmed
empty space about to be create
just like whats in there head
96l will not develope at all.

There is no change to my idea on the system in the northern gulf, it is doing what it was supposed to do, but if anything, we are getting a prime example of what is wrong with TPC and why my two suggested ideas.. 1 on how to classify ( closed rotary circulation, gales in on quad and 2) how to judge the intensity of the storm, incorporating pressure and pressure tendency on a 1-10 scale would be better. In any case a forecaster came in and saw what all saw, that this had a vigorous low to mid level circulation that could cause strong winds in a small area, so he upgraded. What should have been done before could have been handled with special tropical disturbance statements, rather than just blowing it off as a 10% chance. That is not to say it should be named, it is to say that the perception is that there is a sudden jump in intensity, when that is plainly not the case! What happened was a change of the shift and someone looking hard at the data and making a judgement call. Of course you and I have to react, to I have to let all my clients know that its the same as has been described, the weather has not changed, just the forecaster for TPC did and decided to handle it differently
You get what I am talking about. And this person has had several "experiences" where he walked into a hornets nest... a storm that was developing without the previous shift even saying anything. For you Texans.. remember the morning of Allison, the 5 am bulletin, or Humberto?
But like I said, if Alex is any indication, we are in for a long season, and I am talking not only about the actual weather, but the explanations I will have to give. It would be funny if it werent so serious, but it has spread to other matters, non weather related ( I dont know how much more economic recovery I can take over here... I feel guilty the way things have been going so good there too)
I am developing a dark side
Now the most obvious problem in the northwest gulf is still forecasted to not line up the low and mid level centers enough so that it wont be a big storm. But here is the problem and why the area from Corpus Christi to the Louisiana coast should be concerned. These large scale pattern development systems need time to develop. One can plainly see a mid level rotation center east of the northern coast of the Yucatan. Gales are being reported from ships south of the west tip of Cuba where the low and mid level flows are lined up. But the system leans southeast from the low level center near the northeast coast of the Yucatan to the mid level center. If such a system were to line up, look out, another case of rapid feedback development. I dont think this will have the time. However I do think and area of tropical storm conditions, with gales and heavy rains, will pinwheel on the right side of the system, and that means the threat of 6-12 hours of heavy rain... and no matter how its classified ( after what we have been seeing, who knows, right) tropical storm like conditions on the upper Texas or Louisiana coast later Wednesday or Thursday
Now, here is why New England has to sleep with one eye open ( Canadian maritimes too) The upper low that is well east of the coast will back southwest the next several days and entrain the energy from the tropical wave near Puerto Rico. There is plenty of heat around, no doubt about that, the ocean is boiling off the east coast relative to the time of the year. With a major ridge building over the central Atlantic and a trough in the middle of the nation, the area southeast of Hatteras would be a nice place for this wave to get entrained into a falling pressure field caused by the upper low backing, and feedback and develop. A TPC nightmare of course since they tend to ignore things like that, and then its a 50-50 chance if it ever gets classified ( Jersey Devil) anyway. But there is some African influence here and the MJO is locked in octant 2, so one never can be sure if the whack a mole pattern doesnt deliver in cases like this.
Notes and asides: I see the polar temp has been below normal much of the summer
That's a new one.
Meanwhile, looks like wind shear is relaxing in the Carib or is this my magination?

Hi Kristina40, many of us have no more credentials than you have to post here. Don't let the 'spoilers' get you down. I've never felt intimidated here by the PhD's etc... Enjoy! :)
When everybody comes together as one you can learn a lot.
