Was watching last night on radar and its just spinnin away today just east of Dade County. Don't see any deep convection on infra red sat so I'm guessing this is a ULL maybe associated with the cold front that came down?

Sure looks tropical on the radar image...but I'm goin with ULL.

Pretty Pinwheel....

This is a weak surface low, but there's no prospect of any deep convection developing.

The rain we're getting is due to isentropic lifting (warm moist air lifting over a cooler surface air mass, leading to stratiform clouds at the iterface layer with precip). Typically associated with warm fronts, but can happen in isolation like this sometimes.

Its at the surface.

Always need to watch little LLC's. Too much dry air it looks like.

Cloudy, windy and gusty here (upper Keys). Vortex still visible on radar, but not much rain at this time. Trying to check out the winds around this thing, but NW Florida Bay buoy is not reporting. Molasses and Fowey Rocks CMANs showing N to NE at about 20 knots.

Near the NHC, where I live, it has been very cloudy and rainy at periods, all day. It's good to have a cool day that give you a taste of winter!

Man, it is dark here. Only sprinkles of rain so far.
A lot of friends are out on a 22-mile race in Florida Bay, probably a bit rough.

Current fcst discussion:

FLORIDA KEYS AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
348 PM EDT SAT OCT 15 2005

.DISCUSSION...
.OBSERVATIONS/TRENDS...
SKIES ACROSS MOST OF THE MIDDLE AND LOWER KEYS HAVE BECOME MOSTLY
SUNNY EARLY THIS AFTERNOON...WHEREAS IT REMAINS MOSTLY CLOUDY ACROSS
THE UPPER KEYS. PATCHY DRIZZLE IS AFFECTING PORTIONS OF THE UPPER
KEYS AS WELL. WINDS HAVE COME UP TODAY THANKS TO A SHEAR LINE
PASSAGE AND A SMALL 1008MB LOW PRESSURE CENTER DRIFTING OVER THE
STRAITS OF FLORIDA. AIR TRAJECTORIES ACROSS THE KEYS ARE ROOTED IN
HIGHLY MODIFIED CONTINENTAL POLAR AIR...AND DEWPOINTS HAVE DROPPED
TO 71F AT KEY WEST.

A SYNOPTIC-SCALE SURFACE ANALYSIS REVEALED A DIFFUSE AND WEAK
BAROCLINIC ZONE ACROSS THE SOUTHEAST GULF OF MEXICO...SOUTH
FLORIDA...THE NORTHERN BAHAMAS...AND ADJACENT WESTERN NORTH
ATLANTIC. AN EXTRATROPICAL LOW PRESSURE SYSTEM WAS MOVING
NORTH-NORTHEAST OFFSHORE THE EASTERN SEABOARD WHILE A WEAK
CONTINENTAL POLAR HIGH PRESSURE CELL WAS DROPPING SOUTH OUT OF
CANADA. TO THE SOUTH...A TROPICAL DEPRESSION IS PROBABLY FORMING IN
THE VICINITY OF JAMAICA.

.FORECASTS...
STEADY NORTHEAST BREEZES WILL BLOW FOR THE NEXT SEVERAL DAYS...
AVERAGING 14-18KT OVER WATER...AND 13 TO 17 MPH OVER LAND. THERE
WILL PROBABLY BE SOME PEAKS AND LULLS...BUT THE AVERAGE SHOULD BE
VERY NEAR SMALL CRAFT EXERCISE CAUTION CRITERION...AND WINDS HAVE
BEEN RAMPED UP TO 15-20KT FOR FLORIDA BAY AND ATLANTIC WATERS...WITH
NEAR 15KT OVER GULF ZONES. THE INCIPIENT TROPICAL CYCLONE OVER THE
NORTHWEST CARIBBEAN WILL RESIDE IN VERY WEAK STEERING CURRENTS FOR
THE NEXT SEVERAL DAYS AND WILL LIKELY MOVE VERY SLOWLY WEST OR
WEST-NORTHWEST.

CLOUDS AND MIST ASSOCIATED WITH THE MESOSCALE LOW PRESSURE CENTER
EAST OF MIAMI-DADE COUNTY WILL PROBABLY LIFT...BUT THE GENERAL AREA
OF CLOUDINESS SHOULD EVENTUALLY MOVE WEST OR WEST-SOUTHWEST THROUGH
THE KEYS LATE TONIGHT OR SUNDAY. RAIN CHANCES WILL REMAIN SLIGHT
THROUGHOUT THE FORECAST...WITH LOWEST RAIN CHANCES MONDAY AND
TUESDAY. I HAVE TAKEN OUT MENTION OF THUNDER UNTIL TUESDAY NIGHT.
LACK OF INSTABILITY APPEARS TO BE A LIMITING FACTOR UNTIL THEN
ACCORDING TO OBSERVATIONAL TRENDS AND NUMERICAL MODEL OUTPUT.

&&
.MARINE...
SMALL CRAFT SHOULD EXERCISE CAUTION AS NORTH TO NORTHEAST BREEZES
WILL BLOW 15-20KT. HIGHEST SEAS WILL BE FOUND BEYOND THE REEF IN THE
GULF STREAM...UP TO 7FT. SEAS INSIDE THE REEF WILL START OUT
INITIALLY 1-2FT...INCREASING TO 2-3FT WHEN WINDS VEER TO 040-060
DEGREES.

&&
.AVIATION...
AREAS OF MVFR CONDITIONS FOR VISIBILITY AND CEILINGS WILL PERSIST
OVER THE MAINLAND PORTION OF THE KMIA-KEYW FLIGHT ROUTE THROUGH THE
EVENING...AND OVER THE UPPER AND MIDDLE KEYS INCLUDING THE KMTH
TERMINAL. LOCALIZED IFR CONDITIONS WILL OCCUR WITH RAIN...PRODUCING
PERIODS OF CEILINGS BELOW 1000 FEET...AND VISIBILITIES BELOW TWO
MILES. FOR THE LOWER KEYS...INCLUDING THE GULF WATERS NORTH AND THE
KEYW TERMINAL...MAINLY VFR CONDITIONS WILL PREVAIL UNTIL AROUND
SUNSET...WHEN WEATHER CONDITIONS WILL SLOWLY BEGIN TO DETERIORATE.
AREAS OF MVFR CONDITIONS FOR CEILINGS AND/OR VISIBILITIES CAN BE
EXPECTED THROUGH 12Z SUNDAY. SURFACE WINDS AT KEYW AND KMTH WILL
AVERAGE 030/10-15KTS WITH OCCASIONALLY HIGHER GUSTS OF 20-25KTS.

&&
.EYW WATCHES/WARNINGS/ADVISORIES...NONE.

Wait a minute, Florida and winter in the same sentence? :wink:

Sandy, have you experienced a winter up North yet?

Unfortunately, NO. But when I say winter, I mean Miami Winter!

By the way, my barometer shows a pressure of 1009 mb.

I'll trade you a Miami Winter for a Omaha Winter. You can take the "feet" of snow.
