92L ERIN - AND BEYOND

It has been awhile since my last post so I figured I would give my opinions, for what it is worth on the current conditions and beyond.

First of all lets look close to home.

92L

This is a very interesting feature in the Gulf of Mexico. The reason why I say that, is because I look at what changes in the atmosphere it will bring down the road. This is where it could get very interesting for our neck of the woods. Certainly, I could be very wrong ( As Usual), when it comes to tropical forecasting. So here it goes.

Currently, 92L has come off the coast of the Yucatan. There are two important features that determines it future. The first is the Upper Level Low that has dominated the GOM.  First indications a couple days ago this thing would continue to book it to the West and pull out of the way of 92L. Additionally, this would have provided a good amount of venting to allow a closed low circulation to develop and flourish. I never anticipated a strong hurricane out of this due to multiple conditions but thought it could have been named by now.

Finally today, a clear low level circulation has developed. The problem is, the ULL has not moved out of the way. It actually is currently only about 100 miles or so from the low level circulation creating HAVOC on development as far as displacing the thunderstorm away from the center.



What is getting interesting about this feature is that the upper level feature is obviously becoming the dominate low and is currently trying to work its way down to the surface. It is now a mid and upper level low with the low circulation displaced to it's South West.



On the animated loop, you can clearly see the two lows spinning around, with the LLC moving, or being shoved to the South.

Now lets look at the vorticity at the various  levels.

850 MB



500 MB



200 MB



As you can see, all levels are trying to line up. Up until this evening, that was nowhere near the case.

Now the current surface analysis.



Look at that monster trough, front, or dip in the jet stream. What ever you want to call it. This is affecting the moisture flow pulling the rain up to the North into the South East . This will continue to happen. It is affecting this system in more ways than one.

The current modeling of this system is as follows.



GFS Esembles



Intensity Forecast



The CMC has it going to NOLA ( DOOM ) but making a sharp left hand turn  at the last moment



HWRF has it at a 80 KT Hurricane going into Brownsville TX area.



But the main thing to remember her, no matter what the type, Wave, Depression, Tropical Storm, or Hurricane, there will be plenty of water moving into Florida, Alabama, Mississippi and Louisiana. The way the set up is now, Texas should get some rain, even if the landfall would be there, but the bulk of the moisture will be to the East. That channel has already been established.



If you were stuck in this type of steering flow, which way would you move. LOL



In my opinion, this thing will become the F storm. Where it goes is hard to tell. I Don't trust the models yet!

Moving on, Tropical depression Erin.

Little to say. Moving to high to fast. Although it will be moving into slightly warmer water, the dry air that got sucked into the core of the storm devoured it. There is a blow up of storms this evening but may be to little, to late. Either way, no matter what category it would or could become, it affects no one.





Now, what Erin can and is doing, is providing a moist environment for waves to come. This is priming the atmosphere for strong storms down the road.



Now down the road. As we approach the peak of the season in a few weeks, things are following into place.

Let begin with the pressures. You really don't get much development of  nasty Hurricanes when the East Coast is under the influence of low pressures and troughs. You need some High pressure across the Southern US and lower pressures in the Caribbean to have a good gradient or pressure differences to get things in motion. That is exactly what is going to happen. Lets just pick a day and look at things.

120 Hours



Notice the High sets up across the Eastern United States.

Now check this out. With the High pressure in place, a TUTT like feature develops in the Atlantic.



This my friends is where cyclone genesis should occur. The wind shift will get whatever  passes through a chance to develop. I am no way shape or form saying anything will come of this, but the set up is the best it has been as far as environmental conditions so for this year. This is directly related to what is going on now with 92L - The Trough - and Erin. It's all connected as weather events are all across the globe. What happens in the far East effects what happens here at home. AKA Florida. What happens this week here affects what happens next week. Especially when you have exiting areas of low pressure and gets replaced with areas of High Pressure.

There is currently no model support for development in the near future from this but the waves train is going to start flowing from Africa, especially with the MJO predicted by most of the models to be very favorable for something to develop. Just sayin.





I am sure we will have many things to talk about sooner than later.

Peace

Damn it. Forgot to post this for Aug and his cousin

And I can post this here without worry that I ran across on the internets.

Thanks for the blog, e. You do a great job, at explaining everything, with both text and visuals!!!

And a big ole LMAO, at the last pic!!!!

That moisture stream was kind to me, overnight. Had a nice rainfall amount of .88" . Supposed to go kayaking, mid morning, but needless to say, that might not happen.

Wow nice read kept me busy awhile:))...

Damn E. Missed this blog somehow. Nice writeup. Although things didn't materialize this go around, it's that time of year when it could get ugly.

Thanks for the blog E. Very easy to understand.

Damn, 92L went poof. LOL

MJO on the march to the East.





http://mikeventrice.weebly.com/

This area of purple and blue is on the march to the East. Currently, it is over an area that is exploding with tropical activity

I like that graphic, e.... makes it easier to see

Here comes the train



This is the next real AOI methinks



Prolly nothing significant until 55 W or so.

MJO still heading East. Corner is in the GOM. Look at all the activity and moisture now in that region.

F'n imgur isn't cooperating to allow me to post the GIF loop.  So, TD6??  This is at a minimum a moderate TS.

Kinda curious... why would there be a recon flight, if it was going to head inland to Mexico, so quick? For data?

Yep, plus they have a duty to act really. It's all about the science and saving lives. I know it will be short lived over water but if they can put the warning out to save one life, it's worth it. Look for this storm to intensify more before landfall. Very favorable area for this. Looking good

Heading to the second area South of LA and TX. Glad they added that in.

Cool, they are going to use the new drone.

ITCZ becoming very active.

Lots of moisture and spinning going on.

Like I said a couple days ago, look for development to take place just to the West of 50 55. The Multi Model Ensemble TC Genesis Probabilities suggest now.



Not bad odds

MJO still on it's Eastward track



The moisture train is looking impressive.



Half assed attempt to overlay the current MJO over the water vaper. Not exact by no means but you get the picture. Enhanced activity. Just wait untill to moves further East and the Tropical waves move West. High to the North and lowering pressures to the South,

SEASON IS A BUST. Nothing to see here. Carry on

We have two named storms and a yellow circle forecast to have a high chance of development in 5 days. :DOOM: has arrived - unless it hasn't.
