Record cold December in Miami, Florida

By Jason Samenow

Extreme cold follows hottest summer on record

December 2010 had the sunshine state shivering. The National Weather Service reports Miami, Fort Lauderdale, Palm Beach, and Naples - among others - all observed their coldest December on record. In its annual weather review, the National Weather Service Office in Miami said:

A cool and wet January through March was followed by the hottest summer on record, and then concluded with the coldest December on record for the main climate sites in South Florida

Temperatures in southern Florida averaged between 9 and 11 degrees below normal in December. It was colder than average almost every day and one of the coldest months (regardless of time of year) compared to average since the early-to-mid 1980s.

The extreme cold was attributed to the same blocking pattern (negative phase of the North Atlantic Oscillation) in the atmosphere that has transported Arctic air up and down the U.S. East Coast.

I'm not surprised Florida has had a record cold month, with the record blocking over Greenland.

Has this affected the crops there, or is the season over already? Thanks!

It's an interesting analog to the past South American winter where the cold penetrated to the normally warm parts of the Amazon basin killing fish and crops. Even though there was no freeze in Florida as bad as Dec. 1962, what made the whole month cold was that several storms in a row got trapped in NE Canada and the cold penetrated to the central gulf and across the Gulf of Mexico. The water didn't have much of a chance to warm up between cold snaps. The anomaly maps are here showing each week You can also see the anomalously warm water around PEI created on the east side of those storms.

Yellowboy, I only read about frozen tomatoes. When I looked at some of the record lows, they seemed to be about 10 degrees above the all time records so the remarkable thing was the persistent cold not the severity.

Who else would rather be in Acapulco, where it is 77 degrees? Tomorrow's high there will be in the 80s!

I can't believe that it'll be 2011 in 2 days! The temp at the time of the ball drop in NYC should be about 32°.

It's merely more evidence for my contention that "global warming" is a canard, foisted upon us by air conditioner salespersons.

The real issue here is "global extremism", the documentation for which is available every darned day, in every periodical on earth. Sigh...

Happy New Year, y'all!

Yellowboy - I believe that the growing season in Greenland is over now. The crops did just fine.

just because it's cold somewhere, it doesn't mean the GLOBE isn't warming.

I lived in Tampa in 1962. Epic cold: low of 18.3, which was the all-time record. As noted in a previous thread, the most grevious botanical loss were the Australian Pines, which were wiped out.

I was in Miami Jan 24-26, 2003 and they were like, "Oy vey, we've had a really cold winter; I haven't been able to wear my boardshorts when I'm crusing South Beach". I mean, OK, the high one day was 58, but the next day it was in the low 70s.

When I flew back to DCA, the Potomac was frozen solid and we had 40 inches of snow that winter.

According to the monthly report (click on prelim monthly and Dec), Tampa was -10F below normal on average, but only hit 32 twice. Nothing remotely approaching Jerry's 18.3 so this was a more persistent NW flow pattern rather than amplified.
