ATL: BARRY - Post-Tropical

[ozonepete]

For what it's worth, the new 03Z CIMSS analysis shows the strongest vorticity still over Central America:

Southdade, remember that these CIMSS charts are often off by 50-100 miles because of gridding problems. I.e. that 850 mb vorticity center could be 50-100 miles to the north of where they have it.

[Aric Dunn]

yeah a couple. roatan island area have a mix of due north to a little nnw though weak but the pressure field has not had time to expand out given the recent "possible development of the llc ... also it was fairly evident before the sun set

and night ir not as good as the RGB at night

http://www.wunderground.com/wundermap/? ... d.type=00Q

Yeah, southdade, use the rgb at night. Much much better.

I am using RGB. That still uses an IR channel at night, does it not?

yeah but its the filter in the RGB (Red green blue ) that highlight the cloud layers .. night ir does not do that.. the upper clouds over saturate everything below it. now if there are no high or mid leve clouds then yeah the night ir is good.

Ah, ok. I was unaware of that CIMSS issue. Where did you hear that from? And I see what you're saying Aric, I just wish it had the resolution of the visible images. I guess I'm being picky

I can see how a LLC would be just offshore, but I'm not sold it has made it to the surface yet. Very close.

yeah I think it has over very close. I do believe it to be that the pressure field has not expanded out yet but given the sharp increase in the convention all around the "llc" i can imagine taking much longer being that its not over land.

To sort which camp is right you know what? We need Recon!!

Hopefully we have the mission on Monday with takeoff at 17Z.

Oh, ok. We just usually refer to the AVN as IR and the RGB as RGB in order to distinguish them. The RGB is not Infrared. It's a "false-color" interpretation of visible light that gets run through a program that uses the different wavelengths of Red Green and Blue visible light to distinguish heights and code them by color (white, yellow and blue) to show the different cloud levels.

lol yeah.. though by the time recon gets there it might be inland over belize or the yucatan lol but radar out of belize tomorrow shed light on it before recon.

Hi southdade. I learned that about CIMSS from my satellite interpretation courses at Penn State. I will try to find the text and give it to you when I get a chance.

[chaser1]

Yeah I'd like to what light is shed when recon gets in there. On the other hand, if 93L continues to become increasingly organized, than visible satellite might well bear out exactly what we have here

[floridasun78]

i see that some outter band cloud are reaching key west

[Aric Dunn]

i see that some outter band cloud are reaching key west

just high clouds.

[floridasun78]

i see that some outter band cloud are reaching key west

just high clouds.

that what i mean

[Aric Dunn]

I bet they stay 30 just because lol

[Florida1118]

I bet they stay 30 just because lol

Yeeeeeeeeeeeeeeeeeeeppp

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT MON JUN 17 2013

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

A LARGE AREA OF CLOUDINESS AND THUNDERSTORMS EXTENDING FROM EASTERN
HONDURAS NORTHEASTWARD OVER THE NORTHWESTERN CARIBBEAN SEA ARE
ASSOCIATED WITH A TROPICAL WAVE. ALTHOUGH THERE ARE CURRENTLY NO
SIGNS OF A SURFACE CIRCULATION...SOME DEVELOPMENT OF THIS SYSTEM IS
POSSIBLE OVER THE NORTHWEST CARIBBEAN SEA BEFORE IT MOVES INLAND
OVER BELIZE AND THE YUCATAN PENINSULA LATER TODAY. THIS
DISTURBANCE HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS. REGARDLESS OF
DEVELOPMENT...HEAVY RAINS AND GUSTY WINDS ARE LIKELY OVER PORTIONS
OF HONDURAS...THE BAY ISLANDS...GUATEMALA...BELIZE...AND THE
YUCATAN PENINSULA DURING THE NEXT DAY OR SO.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

a bit off topic, but I found this if anybody is interested http://www.nirsoft.net/utils/seqdownload.html
can be used to download satellite/radar images in intervals, I'm using it for Belize radar at the moment.

[Aric Dunn]

typical.... and even about an hour early.. lol probably automated ....

pretty nifty... but a lot of work..

Oh, it just takes about a minute to setup and then its automatic afterwards

[TropicalAnalystwx13]

30% for this system, really? The TWO seems automated at that.

Someone's in a hurry to get over with their shift. I can't help but laugh.

[chaser1]

well, impressive as this continues to look - i'm starting to see evidence that the center may well be over land after all......and slowly developing?!
