More like October than December this week (and not much change this upcoming weekend) per NWS Miami:

THERE ARE SOME INDICATIONS THAT AFTERNOON
TEMPERATURES COULD BE A GOOD 9 TO 10 DEGREES ABOVE CLIMATOLOGICAL
VALUES BOTH WEDNESDAY AND THURSDAY, NEARING RECORD TEMPS OVER THE
SOUTHEAST AREAS DUE TO THE WARM SOUTH TO SOUTHWEST FLOW AHEAD OF
THE FRONT.


The record high in Miami today and tomorrow is 86 deg (set in 1896). The forecast high for today and tomorrow is 87 deg.

[Sanibel]

There's a sharp weather divide with the continent. Paradise weather here in the low 80's with low humidity for the next week while the north has its first rough run of cold winter weather and snow.


Nice bright warm sun here right now after fresh ground Guatemalan coffee and orange juice...

A horizontal cold front dipped into southern Georgia with snow flurries but there's enough of a sharp divide that were are under warm sun and will be in the 70's. Slightly chilly last night but 80 again tomorrow.

[Sanibel]

Caribbean airmass up over us. Unseasonably warm in 80's.


Dewpoint and humidity up near 67 or so.

[jinftl]

Fort Laud: 76.1 deg (+5.5 deg)
West Palm: 75.0 deg (+5.5 deg)

More record heat possible Sunday and Monday across South Florida....from NWS Miami Discussion:

CLIMATE...
HIGH TEMPERATURES TODAY WILL BE IN THE LOWER TO MID 80S OVER THE
CWA...BUT WILL BE WARMING UP INTO THE MID TO UPPER 80S ON SUNDAY.
SUNDAY HIGHS WILL ALSO BE CLOSE TO THE RECORD HIGHS FOR THIS TIME
OF YEAR.

SO WILL MENTION NEAR RECORD HIGHS FOR SUNDAY FOR MOST OF THE CWA.

ON MONDAY THE HIGHS WILL BE IN THE MID 80S WHICH COULD ALSO GET
CLOSE TO THE RECORD HIGHS FOR FORT LAUDERDALE WHICH IS 86, 1922,
MIAMI WHICH IS 86, 1900, AND MIAMI BEACH WHICH IS 82, 2007.

[psyclone]

quite the spread in afternoon temps across the state with 40's and rain up in the panhandle to 70's and 80's down south. it is wonderful over the peninsula today. this is the time of year that latitude really counts. a dose of summer in mid december is pure heaven.

[jinftl]

Can't seem to get a 'meaningful' cold front south of lake o so far this season....no change in that in the next week...

From NWS Miami this afternoon...

.LONG TERM...TUESDAY THROUGH THURSDAY...HERE COMES THE NEXT
FEATURE THAT COULD HAVE SOME KIND OF AN IMPACT IN OUR LOCAL
WEATHER CONDITIONS. LONG RANGE MODELS CONTINUE TO SHOW A DEEPENING
LONG WAVE TROUGH DIGGING SOUTHWARD OVER THE ERN HALF OF THE
COUNTRY WITH ANOTHER FRONTAL SYSTEM DEVELOPING ACROSS THE NRN GULF.
THE FRONT IS EXPECTED TO MOVE SOUTH ACROSS THE PENINSULA TO JUST
NORTH OF LAKE OKEECHOBEE REGION WED EVENING.

HOWEVER MUCH OF THE ENERGY/UPPER LEVEL SUPPORT ASSOCIATED WITH THE PARENT
TROUGH WILL BE DIRECTED NORTHEASTWARD AND THE FRONT IS EXPECTED TO SLOW DOWN
AND STALL AS IT GETS TO THE LOCAL AREA WED NIGHT/THURSDAY. WL
INDICATE SCT POPS WITH THIS SYSTEM...ESPECIALLY WED/WED NIGHT BUT
EXPECT THE SYSTEM TO BECOME DIFFUSE BY THU.

.FRIDAY THROUGH SATURDAY...WX CONDITIONS WILL DEPEND ON WHETHER
THERE IS ANYTHING LEFT FROM THE FRONTAL BOUNDARY AND HOW IT
BEHAVES. MDLS INDICATE THAT IT MAY BEGIN TO MOVE BACK NORTH AS A
WARM FRONT...

[JonathanBelles]

Very interesting GFS model run. A sliver a freezing air AND moisture. If only the surface temps were lower.

1pm observations out of Fort Lauderdale.....unbelievable that it is 12 days before Christmas:

temp: 85
dewpt: 73
heat index: 92


Sunday afternoon on Fort Lauderdale beach:

[psyclone]

a large area of sea fog is lurking just off the west central florida coast as high dewpoint air advects over the cold shelf waters. anywhere from ann maria north could get fogged in quickly should this lurch toward the coast. dewpoints are in the low 70's here.

[JonathanBelles]

WAY too hot for this time of year! 81 here right now!

[tropicana]

indeed, Florida is the envy of most northerners right about now. Some portions of Central Ontario are buried under 3-4 feet of snow thanks to lake effect...and this is only about an hour's drive north of Toronto!

jinftl,I think its the high pressure located in the Greater Antilles that is keeping the fronts from pushing more south.Do you agree with that?

[psyclone]

visited the beach this afternoon and it was socked in with dense fog. visibility was at times under 100 yards. fog has since moved in from the immediate shore with a quarter to half mile visibility in my neighborhood, about 4 miles or so from the coast. sea fog is real winter treat... it reminds me of winter advection fog up north when warm air advances over frozen ground and snow cover.

[JonathanBelles]

Absolutley perfect weather right now!! Not too hot, not too cold, and no rain! If I had the time I would go out into the yard and lay down and watch the clouds go by.
