Discussions indicate S Fla, Tampa, SW Fla.

from Key West discussion:

.FORECAST...
A LOW AND MID LEVEL (1000-500 MB) ANTICYCLONE OVER THE FLORIDA
KEYS...SOUTH FLORIDA AND THE ISLAND OF CUBA WILL MIGRATE WEST INTO
THE GULF OF MEXICO MONDAY. A DEEPENING TROPICAL UPPER TROPOSPHERIC
TROUGH(TUTT) WILL MOVE WEST ACROSS THE BAHAMAS...SOUTH FLORIDA AND
THE KEYS TUESDAY AND WEDNESDAY...BEFORE DEPARTING INTO THE SOUTHEAST
GULF OF MEXICO WEDNESDAY NIGHT. CLIMO POPS MONDAY AND MONDAY NIGHT
WILL BECOME ABOVE AVERAGE TUESDAY THROUGH WEDNESDAY NIGHT.
THEREAFTER...THE WESTERN ATLANTIC RIDGE WILL BUILD BACK ACROSS THE
FLORIDA PENINSULA.

Looks like the Streaker(naked swirl) is coming back to visit Fla. again.

Your link isn't working tailgater.

How do naked swirls become dressed up and ready for business? Are there and dress shops near by?

looks like we have a little counter-clockwise spin going on around 75w / 25n - any connection to the 'low'?

this loop shows it real well:

That spin is an upper low. The water vapor loop gives you a good shot of upper conditions. As you know, an upper low is not so good for tropical development.

Yes, there is an ULL around 25N/75W, but there is also a surface trough just to the west of it with a small swirling eddy near 27.3N/76.6W moving along with it westward, like you said not good for tropical development, plus surface pressures are very high, will just add to the instability for more afternoon thunderstorms to much of FL over the next few days.

Yup. My only point was that WV loops aren't going to show surface circulation. That's the upper low in the WV.

Hmmmm things be changing?

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
250 AM EDT TUE JUN 26 2007

.DISCUSSION...A LITTLE BIT OF A TWIST TO THE CURRENT FORECAST. THE
MID TO UPPER LEVEL LOW THAT HAS BEEN OVER THE ATLANTIC NORTH OF
THE BAHAMAS IS STILL QUITE EVIDENT ON WATER VAPOR IMAGERY. THIS
LOW HAS KEPT THE APPROACHING TROPICAL WAVE WELL TO THE SOUTH OF
THE FLA PENINSULA AND NOW DOES NOT APPEAR THAT THIS WAVE WILL
ACTUALLY AFFECT US. HOWEVER, LOOKING AT THE WATER VAPOR IMAGERIES
THE AFOREMENTIONED LOW IS DRIFTING TO THE WEST. THE GFS DOES NOT
SHOW A CLOSED CIRCULATION WITH THIS LOW (ALTHOUGH IT APPEARS AS
SUCH ON SATELLITE TO BE AS SUCH) IT DOES INDICATE AN OPEN TROUGH.
NONETHELESS, DRY AIR ALOFT ON THE WEST SIDE OF THIS LOW WILL MOVE
ACROSS S FLA TODAY SUPPRESSING MUCH OF THE CONVECTIVE DEVELOPMENT
AND THE MAV GUIDANCE SUPPORTS THIS THINKING. THE CENTER OF THE LOW
SHOULD BE OVER S FLA BY LATE THIS AFTERNOON AND AS IT DRIFTS THEN
INTO THE SE GOFMEX, THE MOISTER AIR ON THE EAST SIDE OF THE LOW
WILL BEGIN MOVING ACROSS OUR REGION AND THE GFS HAS PWAT
INCREASING TO OVER TWO INCHES ON WEDNESDAY.
