As I said last night, there's a lot of energy associated with it.....
SUNDAY 9:00 AM
CLASSIC SUMMER MAP FOR THE FOURTH OF JULY
A blazing heat wave is evolving for much of the east the next several days, and its unclear when temps will go below normal again over the east this month! That doesnt mean the entire month will be as this upcoming week, but it means that the idea of "equal chances" in the east will burn up like dry tinder in a brush fire. NOAA is out of touch again on the heat, as their amazing streak ignoring how hot this summer is over much of the south and east continues. The break in Texas is there, but they will recover as the month wheres on, but plainly the core of the worst heat relative to averages instead of the July Texas to mid atlantic will be mid and north atlantic and into the lakes.. right where much of the nations population can see and feel it.
In the tropics we have several whack a mole systems. There is a tropical wave entering the caribbean, two frontal waves, one in the central gulf that should go into Louisiana tomorrow, the other off Florida, and what may anther western gulf development.. the area of disturbed weather over the western Caribbean. Like Alex, this is not a tropical wave though of course TPC says it is. If it is a wave moving west at 15-20, how is it we have looking at this budding area in the same place for 3 days? Because its not a wave, its gradually lowering pressures and increasing upward motion caused by the pattern and the development of abnormally low pressures, if only by a millibar or two, over abnormally warm water. TPC should send some of their people out the southwest Pacific to watch typhoons develop. That is the kind of situation we have now, simply the overall pattern causing a large area of upward motion. The trackable tropical wave is there coming from the east. One has to remember as these waves get more pronounced we will shift back to the normal atlantic development pattern, which should be abnormally high this year. After all if you have an area favorable for development where one sees thunderstorms just starting to gather, and then you start getting true waves in there, look out. But how do they explains a westward moving wave a 15-20.. in the same general area the past 3 days. Lets see 20 times 24 is 480... times 3 days is 1440. These thunderstorms are not 1440 miles west of where they were starting Thursday and really started cranking Friday.
But if you are going to call 947 mb with a 15 mile wide circular eye a cat 2 ( strongest cat 2 on record) when you had 946 mb further north as a cat 4 in 1957, then I guess you can do that.
Remember the new math is not what the answer is, but what you feel it is.
Bottom line.. We have to watch where this finally shakes out after it gets across the Yucatan. Once the pressure falls consolidate, then we can see where this will develop. The GFS is doing what it always does.. lets heat out so it cant focus it. The Canadian is having a very very tough time this summer folks. Its got so much feedback it spins up everything it sees. That, but the way, may work later in the season. The euro has this back into the western gulf with a west turn again late in the week. One thing, there is alot of heat being released with it and it is something that has to be watched.
Just like I am confident the CFS will have a better idea of the pattern going into the winter season once the La Nina couples correctly and it can just forecast the steady state ( although wild cards such as the affects of high latitude volcanoes TWO YEARS AGO and the low solar cycle may make that tricky) TPC will do great this year in the meet of the season once big storms develop early. The modeling they have is very good at that and so the big ones coming from a long way off will have me singing their praises and agreeing with them. But right now, I dont think they understand that what they are seeing is more like the way typhoons develop.. large scale upward motion with spread out centers of low pressures, and waves that respond not to solid movement, but to feedback of upward motion pulses. Its not unlike thunderstorm boundaries establishing fronts further south in the summer..but with non baroclinic forcing. The have to look at the mean flow over the gulf and the western Caribbean to understand this is not your standard, west moving wave at 15-20 situation. You cant do that with a mean flow 5k-20k the way it is. The 500 mb pattern is wild in 48-72, for geeks like me. When do you see the mean upper flow, as analyzed every 10dm, in Chicago coming from south of central America! The surge at 850 mb is already to the Yucatan how do you have thunderstorms clustering 500 miles south east of there if this is not a process that involves several factors, not tropical wave moving west at 15-20?
Time to head to NYC for the fireworks
ciao for now ****
95L goes into Tx/La border, then you see where 96L goes,,, Texas.... then there is a "system' that crosses Fla into the GOM and into Tx. then another "system' develops off Panama/Columbia and hits Nicaragua/Honduras, Then another "system" develops just west of the ABC islands.
That's a scenario i don't wanna see
WOW
thats what you get for surfing the web with a hamburger :)
LOL!!
This is the tropical process at work.. Takes time to cook in the oven
if its even close.... your going to be a busy little camper
I know nothing about weather. I just like following and learning. I was just typing what I saw on the imagery. Ask the knowledgeable as to the model credibility before cancelling a trip.
Im using firefox and see everything just fine. However Im on a Mac and that could be the difference..
No Active Tropical Warnings in the Atlantic, Caribbean, or Gulf of Mexico
As of Sun 04 Jul 2010 14:30:02Z
unless MH09, but what if the vort max moves toward SW Jamaica. I have seen this happen before.With the Obs well they change as well and maybe we are all seeing COC, maybe we have multiple COC like 93L/ALEX, but weaker, well let us see what happens. Also if you look at the past track using BEST track plots, you will see that it had move quite far SW south of Jamaica. I belive the first two plots are right but, I think it continued WNW-NW and they caught up on another COC, but anyway let us see what pan out.
is this better for ya MH09
As much as I don't enjoy the basically unfounded criticism of TPC, he is right about the heat wave. All models develop a huge H500 ridge nearly coast to coast thru the week with ECMWF developing a > 600 dm ridge (that means widespread highs > 100F and lows around 80F) thru most of the continental US during the next 7 days and beyond. Heat waves, in the aggregate, can be as much of a threat to health than can any single Hurricane.
I don't like that model run at all... Hopefully the next one drops the storm going through SFL...
A WU drama warning is now in effect on Dr. Masters blog. Take all necessary precautions to protect life and property and sanity!
$$$
i wish him the best
get some rest
all ten of the same
will still be here
when he gets back
tell him KOTG says that
This area should still be watched,considering that is how some July storms form in that area.The U.S.A Atlantic coast south of North Carolina is a hotspot for TC formation.
Any chance of a Orange circle by 2:00 PM?
Ouch, been there done that...
Keep us posted please.
rare form today I see
High pressure is the USA's best friend...unless it's too hot.....
LOL.
1030 AM CDT SUN JUL 04 2010
.SYNOPSIS...A STATIONARY FRONT EXTENDS FROM NEAR CEDAR KEY
FLORIDA TO A 1012 MB LOW NEAR 27N90W. THE LOW IS FORECAST TO
TURN NW AND REACH THE SOUTHERN LOUISIANA COAST TONIGHT INTO
EARLY MON AS IT BECOMES DIFFUSE. HIGH PRES CENTERED OFF THE U.S.
EASTERN SEABOARD WILL BUILD A RIDGE SW ACROSS THE NORTHERN
PORTION OF THE GULF EARLY NEXT WEEK. THE NORTHERN PORTION OF A
TROPICAL WAVE OR POSSIBLY A LOW PRES SYSTEM IS EXPECTED TO MOVE
ACROSS THE NORTHERN YUCATAN PENINSULA LATE MON AFTERNOON AND
EVENING AND INTO THE SW GULF TUE AND WED. THIS SYSTEM MAY THEN
REACH THE MEXICAN COAST THU.
Actually... have not had breakfast yet... SWMBO is still dead to the world. IF it does not rain... will wake her up and have brekkie, then golfing.
going to have the check the Seismic monitor later.. house just did the shaky thingie.
FOUR!
Reminds me of 93L...
Wow, didn't notice that, but 456 did. No vorticity, though.
Just like Alex.
