That's a frigid day in any month.
Boston isn't the only part of the country experiencing cold, according to the weather service.
Partly cloudy, 50-degree weather is forecast to continue through next weekend, with some showers possible on Saturday and Sunday.
In other words, middle autumn will play deep January for a day today.
It brought cold rain, some snowflakes and warnings for this morning's commuters to keep an eye out for black ice on bridges and overpasses.
Johnson said new record lows for November 11 were also set this morning in Newark (24 degrees) and Allentown (18 degrees), and tied in Reading, Pa. (18 degrees).
That would set another record for cold.
A third record could also fall after the calendar flips to Saturday with an overnight low of 16 degrees forecast.
The average low temperature for the region at this time of year is 38 degrees. That would eclipse the coldest Veterans Day on record - 19 degrees, set in 1957.
"Root said the cold front will also usher in windy conditions and northwesterly gusts of up to 40 miles per hour will make the afternoon high of 38 degrees feel more like the mid-20s".
Temperatures are expected to warm up to the low-50s by Monday, still remaining below average, he said.
Sunday is expected to be sunny and slightly warmer with a high of 43 degrees, according to forecasters.
