Come on press, it's the theme song to North by Northwest!!!! If Cary Grant could do it, so can you. Movie took place in the Dakota's by the way. LOL
is it the 1st week of SEP or the last week of SEP?
It looks the nicest of any central Atlantic wave we've had so far. It may prove significant if it piles its energy into the west Caribbean and Gulf of Mexico later next week.
Here is a closer view.
It's pretty bad when I'm like BEGGING the NHC to use thier crayons, I oughtta send'm some...remember last year I went to every Walmart and Kmart in the Miami-Dade region and bought them all out.
The 500 mb level is often refered to as the steering level as most weather systems and precipitation follow the winds at this level. The winds follow the height contours and generally run from 30 to 100 knots. The speeds can be roughly estimated from the 300 mb winds as roughly 2/3rds their magnitude. This level averages around 18,000 feet above sea level and is roughly half-way up through the weather producing part of the atmosphere called the troposphere.
The 850 mb chart details weather conditions at the 850 mb level or around 5000 feet above sea level.
well something along those lines the link can explain it better then I.

US National Solar Observatory
Is the Sunspot Cycle Going into Hybernation?
Be sure to read the added note, perhaps first. One of the authors stresses that they are NOT predicting a mini-ice age.
Sadly, more fodder for the global warming conflict.
Anyways, we may not see sunspot cycle #25 for some time, perhaps decades, if the authors are correct.
Interesting read.

USA Today: Looming gap in weather satellites threatens forecasting
Wow.Wow.Wow. The Feds gave NWS the radar. There will be a learning curve for mets before it's fully implemented, but still... Wow.
From the link:
The dual polarization system, which was installed inside the National Weather Service's radar tower about two weeks ago, now is up and running as part of a six-month test run across the United States. Phoenix-Mesa Gateway is the nation's first airport to receive the technology, with five more cities to follow: Norman, Okla.; Vance Air Force Base, Okla.; Wichita, Kan.; Pittsburgh, Pa., and Morehead City, N.C.
Its effectiveness will be reviewed in the months ahead before 131 dual polarization systems are deployed across the nation by mid-2013...
Doesn't sound like a looming gap to me. That's a delay of 18 months with a 24-month fuel buffer. It's not like the thing is going to fall apart on the last day of the 5th year. It would be nice to have a 2-year buffer rather than a 6-month buffer, but the US is in quite dire straights financially.
mindless idle banter
Don't worry though, we're going to be seeing some action within the next 3 weeks more than likely.
I hear thunder outside.
BBL.
interesting
The same model run will show both 850 and 500. Levels is the difference. 850 closer to surface, 500 midlevel.

N by NW, just Mt. Rushmore. The Iowa cornfield scene was the best.

Slow day at the blogs, ain't it? :)
Thank you!
I know! I can't wait.
I believe it is Sept 5th this year
A SURFACE RIDGE AXIS IS OVER THE GULF OF MEXICO ALONG 29N. 5-10
KT SOUTHERLY WINDS ARE OVER THE E GULF WHILE 10-15 KT SOUTHERLY
FLOW IS OVER THE W GULF DUE TO A SLIGHTLY TIGHTER SURFACE
GRADIENT. FAIR WEATHER IS OVER THE GULF EXCEPT OVER THE SE GULF.
A TROPICAL WAVE IS NOW IN THE YUCATAN CHANNEL PRODUCING
SCATTERED SHOWERS S OF 24N E OF 87W. IN THE UPPER LEVELS AN
UPPER LEVEL HIGH IS CENTERED OVER N MEXICO NEAR 25N100W. STRONG
SUBSIDENCE COVERS THE GULF EXCEPT OVER FLORIDA...CUBA...AND THE
YUCATAN PENINSULA. EXPECT...MORE THUNDERSTORMS OVER THE STRAITS
OF FLORIDA...CUBA...THE YUCATAN CHANNEL...AND THE YUCATAN
PENINSULA OVER THE NEXT 24 HOURS.
That is a pretty active picture for mid-June.
yep. My brain's so fried, I can't even add in to the mindlessness.

Carribean wave*
It has a decent chance to get classified as a TD or weak TS, but I don't see it getting too strong, as the upper-level pattern is not favorable.
This product uses geosynchronous satellite imagery and therefore has the advantage of full coverage in space and frequent coverage in time. It uses cloud top temperatures as a proxy for surface convergence.
The top plot shows the latest infrared (IR) brightness temperatures from GOES Channel 4.
The bottom plot is a Hovmoller (time-latitude) diagram of the zonal mean brightness temperatures, newest time on the bottom. This allows you to track the evolution of the ITCZ(s).
