Whew Florida got Smacked Up!
If a troughing pattern sets up for the West coast, what does it mean for the East???
8 to 10 DAY 500MB MEAN
Yuo just said it pretty well. It's a distubance that needs to be watched. I believe it's expected to drift NW in to Mexico. Lets keep an eye on it though.
There are 3 more photos in the series, click on my profile, and a video at http://www.youtube.com/watch?v=clIlMApwv1o

I hope this is done right. The tightly clustered is the Dynamic and the other is Statistical. I am not Patrap.
99L isn't dead yet, but the chances are very slim it's devlopment.
100,000 comments. WOW!
Correct....
65k of em are from his blog.
Sorry I don't was only going by what they discussed and showed on TWC, I'm sure some one here will be able to give you a link though!
68 comments.......I wish I was more like you....and I mean that.
this time in 1979 we were watching Hurricane David..

Moisture starved......but not dead by any means. You agree?
LOL...I'm strictly a lurker..lots to learn and little to contribute...BTW, the weather is truly grand here in NOLA today! Cut the grass for the first time in three weeks. The neighbors want to throw me a party!

These models are still running on Gaston, don't know if that's what people are looking for, but here they are.
I think the bottom is stastical and the top dynamic...not sure. I think Pats are flipped from yours.....I think.

AN UPPER LEVEL LONGWAVE TROUGH IS LOCATED OVER MUCH OF THE
EASTERN CONUS THAT DIPS TO 29N. EMBEDDED WITHIN THIS
TROUGHING...AN UPPER LEVEL SHORTWAVE TROUGH WITH AXIS ALONG 90W
IS OVER THE CENTRAL GULF WATERS. THE LONGWAVE TROUGH SUPPORTS A
COLD FRONT THAT EXTENDS ACROSS THE FLORIDA PANHANDLE AND ENTERS
THE GULF NEAR 30N86W THEN WESTWARD TO 29N90W OVER SE LOUISIANA
THEN TO THE TEXAS COAST NEAR 27N97W. THE SHORTWAVE TROUGH
SUPPORTS A PAIR OF SURFACE TROUGHS. ONE IS ANALYZED FROM 28N86W
TO 24N92W WITH SCATTERED SHOWERS AND TSTMS WITHIN 120 NM OF THE
TROUGH AXIS. THE OTHER SURFACE TROUGH IS ANALYZED ALONG 28N93W
23N96W TO 19N95W WITH SCATTERED SHOWERS AND TSTMS WITHIN 120 NM
OF THE MEXICO COAST S OF 25N AND OVER THE SW GULF S OF 24N W OF
92W. WHILE LOWER PRESSURE VALUES EXIST OVER THE SW GULF...GLOBAL
MODELS ARE INDICATING CYCLOGENESIS IS POSSIBLE OVER THE NEXT
12-24 HOURS. ELSEWHERE...OVER THE REMAINDER OF THE GULF E OF
90W...AN UPPER LEVEL ANTICYCLONE IS ANCHORED OVER FLORIDA
STRAITS NEAR 25N81W AND EXTENDS AN UPPER LEVEL RIDGE AXIS SW TO
THE YUCATAN CHANNEL. WIDELY SCATTERED SHOWERS ARE OCCURRING FROM
23N-26N BETWEEN 78W-85W.
Looks like there's another spin due south of TX/LA border. Best I can tell it's low level.

Is Gaston's remnants something we should be watching on the Northern Gulf Coast or when/if it develops is it pretty well pre determined that it wouldn't get that far West?
Thanks in advance for any answers!
Gastonlookin'badder
Looks better than it did a few hours ago when I saw it!
actually that was before computers and TWC,
we were "watching" it the best we could on the major network channels..
Aug 25 - Sept 9th, 1979
I was new the Florida just moved here from Memphis in July...
and I had the big paper map to place all the dots every 3 hours for the updated positions..
It was coming our way...
then had a baby on Aug 30th as we went under watches...and got to come home from hospital just in time to board up!
Also, this time in 2004 we were watching Ivan the Terrible which formed as a TD on Sept 2 and became a hurricane on Sept 5.
Hey xcool. :) Those models don't look good for Caribbean. :(
Its way too far out for people on the Gulf Coast to worry. Ask again in about 5-7 days. :)
Agreed, he tried last night but just couldn't hold the convection.....as you know.
but the blog where not a round at this time
