I had my doubts the models were right on the dewpoints in south florida for today but it looks like they were pretty close. Nam/gfs had been showing dewpoints as low as near 0, (even below zero in miami at one point) but moderated into the single digits/teens as we drew closer today. Indeed, dewpoints are in the teens and single digits inland...especially from the lake northward. Even the east coast of florida has single digits which is incredible I think since usually the ocean is able to moderate/moisten the atmosphere a little. But the high/flow is just right to drain that cold dry air down the peninsula. To me the dewpoints are every bit as impressive as the temperatures.

Fire danger is extreme.....

Mid 30s in Miami with wind this morning must have felt frigid. 50F with wind in Key West was probably equally frigid. Does everyone have heat in Key West?

I'm sure the locals have heaters. The hotels will have heat.

I haven't put the heat on in my house yet. Last night was 33 IMBY. Its OK w/ sweaters/blankets.

NWS San Juan (Puerto Rico)

.DISCUSSION...A COLD FRONT IS EXPECTED TO REACH THE LOCAL

ATLANTIC WATERS LATE TONIGHT...AND THEN MOVE SLOWLY SOUTHEAST

ACROSS THE LOCAL AREA WEDNESDAY THROUGH THURSDAY. PER NCEP

COORDINATION AND MODEL PROJECTIONS...EXPECT THIS BOUNDARY TO BE A

SLOW MOVER AND SHOULD BE ENOUGH MOISTURE AND MID TO UPPER LEVEL

JET DYNAMICS AVAILABLE...TO RESULT IN A PERIOD OF ACTIVE

WEATHER...PROBABLY LATE TONIGHT THROUGH MOST OF WEDNESDAY...WITH

THE NORTH AND INTERIOR SECTIONS OF PUERTO RICO MOST AT RISK FOR AT

LEAST SOME LOCALLY HEAVY RAINFALL AND THE POTENTIAL FOR AT LEAST

SOME MINOR FLOODING. HAVE MADE SOME CHANGES TO SHORT TERM GRIDS

TO TRY TO SHOW THIS THINKING. REMNANTS OF BOUNDARY WILL LINGER

ACROSS THE LOCAL ISLANDS THROUGH THURSDAY AND POSSIBLY THURSDAY

NIGHT...BEFORE IT IS FAR ENOUGH SOUTH OF THE LOCAL ISLANDS AND

WEAK ENOUGH THAT IT SHOULD NOT HAVE A BIG EFFECT ON THE LOCAL

SENSIBLE WEATHER. AT THIS TIME...GENERALLY FAIR AND DRIER

CONDITIONS ARE INDICATED FOR FRIDAY AND SATURDAY.

Looks like these fronts do make it pretty far south.

Dewpoints are mighty impressive. Here's a graph of mine today. Briefly went below 0 for a bit.

All time record low in Miami

27°

2/3/1917

Record low for the month of December in Miami is 30° (Christmas 1989)

thanks for that info. Thats some very impressive cold in Florida, this amplified pattern did the job. Just 9 degrees from the all time low. Thats like my area getting to 1 or 2 degrees. I think our all time low is -7 or -8.

I am glad we did not see any of those seemingly obligatory "It is not even winter yet" responses. The majority of winter weather is late November through about March 1...not what the calendar says.

I agree.. I always think of Thanksgiving or December 1st as my start to winter and March is a start to Spring.

How did the crops fare during the past week. My family loves the OJ and just curious. Thanks

My moms maters and peppers had 3rd degree burns, and are toast, this is in Brevard County (east central FL, same county the space shuttle launches from). She lives on the inter-coastal so there is some modification from the water, but a stiff NW puts CAA into full effect. She lost several palm trees last winter with a lesser cold snap, so imagine a few more will be dead this year. Very unusual to see most of the peninsula under hard freeze warnings, two nights in a row, especially in the first part of Dec. Stock up on the OJ now as prices are likely to go through the roof once the damage is tallied on the crop.
