All in all, if what is projected occurs, it will be an extraordinary event as the thermometer goes below 50 degrees Fahrenheit on the morning of Tuesday, November 11. The last time this occurred on a November day was in November 22, 2006, when the temperature reached 45 degrees Fahrenheit.
That was the only occurrence of this phenomenon in the previous 40 years. Before that, it happened in 1984. However, it once was quite commonplace, and looking at the overall climatological record in the last century, one could expect it to have been an annual event.
Wow?? Thats a lots of historical data. Is all of it exclusively comparing November low temperatures? Thanks for digging up those few dates in Miami where temps did dip into the 40's. I had forgotten that did occur. The fact that Miami had far more frequent occurances of November low temps in the 40's prior to 1984 does fit with my fuzzy recollection when living down there since 1970. That implies any or all of three possibilities.
1) NHC may have needed to move the exact location of the MIA reporting station at some point during the '80's, which might have impacted minimum temperature readings.
2) Heat Sink affect. Population and construction expansion over several decades have contributed to higher temps.
3) Global Warming
