Well, if it does develop, it's going to be a large one (diameter), judging from how large of an area is feeding into it. Shear looks low in the area. Needs a lot more convection, though. If convection flares up, I'd expect it to take off.
She's not a dude.

ignoring his comments is one thing..but humiliating a human being is another..just move on bro.
You're definitely sure it's going to the SC coast?
oops my mistake..
Yep...just takes the right set of circumstances
I agree. While we all know that JFVWS tends to get to the annoying status pretty quick, we are also now getting the benefit of being annoyed in absentia by people who can't let go even when he's not here. C'mon people..at least wait until he's here to rag on him and enjoy the quiet when he's not.
Depends how strong the trough is, it could sharply recurve... Yet you could have a Floyd (1999) and recurve it long and slow up the coastline. It's just wayy to early to make assumptions right now, check back in a few days but most of all, check your local news station for the best coverage. :)
Of course it has nothing to do with how the coast is shaped and that OBX is kind of sticking istelf out to the east...
Yep, plus this invest is really getting sheared right now. Until that upper level low moves out of the way, no development at all. I was actually surprised to see an orange code then a yellow one.
I guess for me, these "quick-trigger" systems tend to keep us on our toes in emergency management. Being in the Cntral Florida area, we're kind of forced to ask "what-if" a lot. Mostly because the ramp-up of operations is based on 3-day notifications.
BTW...afternoon, all!

.DISCUSSION...
STRANGE SUMMER CONTINUES AS WE ARE DEALING WITH PLEASANT WEATHER
INSTEAD OF THE TYPICAL LATE AUGUST HEAT AND HUMIDITY. FOR NOW AND
THE NEXT DAY OR SO...THE WEATHER LOOKS TO REMAIN RELATIVELY
BENIGN WITH HIGHS AT OR BELOW NORMAL AND THE HUMIDITY VALUES ON
THE RISE...BUT STILL BELOW NORMAL FOR THIS TIME OF YEAR.
THE ONLY MONKEY IN THE WRENCH IS THE FAINT REMNANTS OF THE UPPER
LEVEL TROF HUGGING THE EAST COAST. MODELS CONTINUE TO INDICATE
THAT WHILE THE BULK OF THE TROF AXIS EXITS STAGE RIGHT...THE
SOUTHERN MOST TIP ACTUALLY RETROGRADES WESTWARD OVER MUCH OF THE
SOUTHEAST THROUGH THE BULK OF THE WORK WEEK. THIS WILL CREATE A
VERY MESSY FORECAST AS THIS REMNANT LOW BECOMES A SLIGHTLY DEEPER
CLOSED LOW BY TOMORROW AS IT CONTINUES ON ITS WESTWARD PATH. THIS
MAY SEEM TO BE A SMALL DETAIL...BUT IT WILL EVENTUALLY PLAY A
MAJOR ROLE AS WEATHER MAKER BY WEDNESDAY AND ESPECIALLY INTO
THURSDAY. AS THIS LOW PULLS JUST TO OUR WEST IT WILL ACT TO CREATE
A HEIGHT FALLS SURFACE LOW WHICH WILL RAPIDLY PULL ATLANTIC AND
GULF AIR BACK OVER THE REGION. THIS WILL CREATE A MORE CONDUCIVE ENVIRONMENT
FOR SHOWERS AND THUNDERSTORMS FROM WEDNESDAY THROUGH AT LEAST
FRIDAY. IT WILL HAVE A RATHER STRANGE LOOK AS THE POSITION OF THIS
LOW WILL PULL MOISTURE AND STORMS FROM THE SOUTHEAST...SO WILL
HAVE THE UNUSUAL SOUTHEAST TO NORTHWESTERLY STORM TRACK. THIS SYSTEM HAS
THE POTENTIAL TO BE A FORECAST BUSTER...EVEN AS I TYPE SHOWERS
ARE FORMING ALONG THE TRAILING EDGE OF THE SYSTEM AS AN ALMOST
WEDGE FRONT INDUCED LINE.
WHILE THIS SEEMS A BIT COMPLEX THINGS TREND MORE TOWARDS THE 2009
SUMMER AS YET ANOTHER STRONG COLD FRONT PLUNGES SOUTH OVER THE
WEEKEND...AND WE COULD BE LOOKING AT MORE RECORD LOWS BY THIS TIME
NEXT WEEK. NORMALLY...I WOULD NOT BITE ON THIS
SCENARIO...HOWEVER...GIVEN THIS SUMMER ONE COULD AND SHOULD EXPECT
THE UNEXPECTED.
-CanesRule1.
It is still Orange on the NHC site.
great question..i would like to know myself!!
"LONG TERM...(THURSDAY ON)THURSDAY...THE CLOSED UPPER LOW OVER THE
LOWER MISS RIVER VALLEY BEGINS TO BREAK DOWN AS A SHORTWAVE HEADS
SOUTHEAST FROM OVER THE PLAINS. THIS WILL KICK THE LOWER MISS RIVER
SYSTEM THROUGH THE UPPER TROUGH WHICH HAS SET UP OVER THE MISS RIVER
VALLEY BY THIS TIME. GFS IS ADVERTISING A GAP IN THE PRECIP FRIDAY
INTO FRIDAY NIGHT...THEN ANOTHER ROUND AS THIS SECOND ROUND OF UPPER
ENERGY APPROACHES THE AREA...DRAGGING A FRONT WITH...WHICH IS BEING
ADVERTISED MOVING SLOWLY OVER THE FA SUNDAY INTO MONDAY.
I know, I was just surprised they put higher chances on it. Though I guess with all the model support...
....and lessening that shear. That ULL will move to the southwest and weaken, giving 92L favorable conditions to develop in.
Because they're the best way they have to predict future movements, but again, weak, "low" storms don't forecast very well; once they acheive hurricane status forecasting becomes considerably easier and more acurate
It rains and steam rises from the pavement. Please send the cold front down here...
AS FOR THE TROPICS...NHC HAS INCLUDED A WAVE WITH A MEDIUM CHANCE
OF DEVELOPMENT IN THE TROPICAL WEATHER OUTLOOK. EVEN IF THIS
SYSTEM DOES DEVELOP INTO A TROPICAL STORM OR HURRICANE...ALL MODEL
GUIDANCE CURRENTLY AGREES THAT THE EAST COAST TROUGH WILL REMAIN
IN PLACE LONG ENOUGH TO FORCE THIS SYSTEM TO RECURVE BEFORE
AFFECTING THE CONTINENTAL UNITED STATES.

That is the story of the summer. With this scenario, the east coast of FL. is pretty well protected.
It's nice up here. I've got 83 degrees outside.
Tonight
Partly cloudy. Lows around 59. Light winds.

A bit overconfident there...
Here's hoping this blows out to sea as well.
They are correct. Most model guidance does keep it well of the NC coast.
