Call it what you want but satellite clearly shows an independent low pressure system.

Then why hasn't the NHC upgraded it to a subtropical depression?

Obviously 95L is still attached to the frontal boundary.

Don't see this happening at this time.

Oh no, round two? Not again! Haven't ya'll beaten the crap out of this horse enough already!

Ant that special!!

Tropical weather Gods...please get 95L inland and dissipated.

TIA!

Instead of playing the NHC frontal map card and look at Visible Satellite imagery and tell me the circulation isn't independent from that frontal boundary.

feel like we may be starting to get cyclogenesis

96L 30% of developing....not what I was expecting at all today.....Thought for sure it would be a depression today. hmmmm

Your right he should check for himself, but still I'd think the NHC would've checked too before they made that map...lol

We need a new blog. This one tastes a bit stale.

Just like Alex, the same kind of energy has piled up in the wCaribbean. There is broad, general circulation, but unlike Alex, the steering flow is more northerly. And, I am less concerned about dry air than I am any shearing component. SST's are warm enough to generate surface lift and an adequate moisture field for development. The energy and the circulation will have to tighten around a central, surface circulation, but it has ample time to do that still. Additionally, the flow from the frontal system to the west will aid the moisture field and northerly steering.

So the NHC map is wrong, very interesting.

LOL! True, however, whatever frontal boundary that was over SE LA has degenerated. Low level clouds are clearly being influenced by the low pressure system just off Lafourche Parish. There still could be something left of that boundary over in Florida though.

No he is saying that the NHC made sure it was still attached to the front before they created the surface chart that still has it attached to the front

4021. Yeah, Pat, if 95L had a bit more time over water, I don't think it'd be quite so disrespected. Still, it can and likely will cause plenty of trouble as it is. Pesky, stubborn little system despite the dry air.

I'm agreeing with you, not saying the NHC is wrong lol

Quoting MiamiHurricanes09:
One thing I've noted from this blog is that most of you don't have much patience.

It has nothing to do with patience. I just don't understand why these systems just don't either materialize or dissipate in ten or so minutes. It's just so unfair and unnerving!!!

Quoting extreme236:

LOL, I get it now.

Got a feeling 95L will hang around on land long enough to some how effect 96L path.
hope not though.

Area forecast discussion
National Weather Service New Orleans la
108 PM CDT Monday Jul 5 2010


Update...
a coastal Flood Watch has been issued for the coastal
sections of southeast Mississippi and southeast Louisiana late
tonight through midday Wednesday. Coastal flooding may occur as with
high astronomical tides combine with above normal water levels and
an increasing southeasterly wind flow. The threat for coastal
flooding is higher on Wednesday morning than on Tuesday morning.


&&


Aviation...
deep moisture is over the area with precipitatble
water levels over 2.25 inches. Bands of convection are wrapping northwest
across the area around a low pressure center about 40 nm south of
Houma. In the short term...18z tafs account for convection over southeast
Mississippi and areas generally north of I-12...a lull between the
convection to the north and new convection firing up near the
mouth of the Mississippi River that is wrapping to the northwest.
Expect convection to become more scattered after 03z. VFR to MVFR
conditions will dominate. In thunderstorms...visibilities will fall to
1-3sm in precipitation with ceilings falling to bkn012-015cb.

&&


Marine...
a small non-tropical low sitting over the near shore waters south
of Morgan City will move northwest through this afternoon then
dissipate as it moves inland. SW winds 10-15 knots dominate today
with some gusts to 20-25 knots around thunderstorms.


Short term models forecast tightening pressure gradients later tonight
through early Wednesday with high pressure remaining over Georgia and an
inverted trough extending north from a tropical wave in the
northwest Caribbean moves northwest into the central Gulf. Small
craft advisories were issued for the coastal waters for tonight
through Wednesday as winds rise to around 20 knots. The 12z nam12 has
stronger winds Tuesday into early Wednesday with some 30-35 knots reaching the
Gulf waters east of the mouth of the Mississippi River. The nam12
is also faster than the other short term guidance increasing winds
early this evening. The GFS and sref models also increase
winds...but only to around 20-25 knots and are about 12 hours slower
in the evolution of the wind field over the eastern have of the
coastal waters. At this point forecasts split the difference but
more in the direction of the GFS.


The area of disturbed weather in the northwest Caribbean is less
organized that 24 hours ago. Current National Hurricane Center
forecasts indicate that the wave will work northwest into the
central Gulf by midday Wednesday then head toward the Upper Texas or
southwest Louisiana coast. There is about a 30 percent chance that
this system will develop into a tropical cyclone. Swell to the
northwest of this wave are expected to rise to about 8 feet north the
outer Gulf waters Wednesday. Conditions will improve from the east
Thursday and Friday.

i live in east haven conn the temp is 98F AT 2:25PM..ITS GOING TO BE VERY HOT FOR THE NORTHEAST ALL WEEK LONG..WOW IS HOT HERE..

Drink plenty of water & Gatorade, stay out of the sun during the hottest part of the day, stay in an air-conditioned place.

I live in TX, you are experiencing what we have in North TX for about 2 1/2 mos. Do NOT overdue it in the heat, it can cause you to become very ill or worse!!

A moot point as far as impact goes.

Well, at least the humidity is only around 30%. So far. Stay air-conditioned, wear light, light-colored clothing, stay hydrated. Looks like things will start to cool off a bit on Thursday.

I have not gone far enough back in the blog to see if the Ascat pass has been posted yet but if not it clearly shows that there is no surface low near the coast of Honduras. Lots of high winds but that is all. 96L appears to be on the way NW through the channel.
