A few minutes before sunrise, the ‘feels-like’ temperature in Key Biscayne was 35 degrees, and if you were like many, you had a good reason to stay under the covers. 

Schools were closed for the Veterans Day holiday, but those who were outside —  joggers, delivery persons, and dogwalkers, were bundling up with hoodies, jackets, and gloves. 

The 50.9 degree temperature didn’t set an all-time Miami record, but it’s the lowest in the 32-year record of instruments placed at the University of Miami’s Rosenstiel School on Virginia Key. 

The previous Virginia Key low was 60.6 degrees, set in 1996. The average low for today’s date is 72.4, according to Brian McNoldy, a meteorologist at Rosenstiel. 

“Breaking a record low by 10 degrees F is incredible,” he said. “That’s a huge margin.” McNoldy said the earliest 50-degree morning on Virginia Key — up till now — took place on Nov. 22, back in 2006.

The National Weather Service forecast says while it’ll get warmer as the day goes on, colder air in the upper atmosphere will prevent a swift return to normal. 

“While we`ll be under the influence of full sunshine this afternoon, the temperatures aloft will be in the bottom 10th percentile for this time of year, which won`t allow temperatures to climb much due to mixing,” forecasters wrote. 

Later in the week, there’s a warming trend, with Wednesday morning’s low a relatively balmy 68 degrees.
