The model has 3 consecutive nights of below zero weather here N/W of the metros. Probably have to go back quite a ways to find the last time that happened.
The temps are the weeniest part of that depiction. Colder than Feb 2003. Colder than the second storm in Jan 1987. Almost on par with the blizzard at the end of Jan 1966.
Philly got another 3” on the 12th, after the blizzard. I visited the city a week or so later when the flooding happened. Can still recall seeing the Schuylkill River at bank full. What an extreme month that was !
Made it to 44° this afternoon. MRB was -2.8 for the month before today. That negative departure is gonna take a beating the last 4 days of the month, but we should end up -0.5 to -1.0.
Snowfall in January is a pretty good bet. IAD has had 1 season in the past 50 years without measurable snow in January (2023). At BWI it has happened twice (2006, 2023). Even DCA has had some kind of accumulation in 45 of the past 50 years.
I mentioned it the other day, but that early January 1970 cold snap was really frigid. I have some great memories of sledding on snow as hard as concrete.
Here was the peak of it at BWI
December 1963 is on that list too and finished around -10 for the month.
Then some front end action from an OV low on the 7th followed by freezing temperatures down to central FL. Good start to what looks like a wintry January.
It’s been a nice start to winter here. MRB is -2.6° for the month with only a few mild days so far. Should be at about -3.5° heading into Christmas Eve. Precip has been above normal and it’s already snowed a couple of inches. Happy to see the moisture showing up after such a dry year.
