The one near-miss from that part of the calendar that still bothers me is March 1-2, 1980. The DC-BALT corridor pulled off a 4-6” snowfall with temps in the upper teens, but eastern NC up to the Tidewater of VA had 1-2 feet with similar temps.

I chased to Virginia Beach in early January 2017. Stayed in a cabin at First Landing State Park. Would highly recommend. The rangers actually shoveled us out.
There was a blizzard warning in effect and winds on the beach were over 55 mph. Plows were running and with a four wheel drive vehicle I had no difficulty getting around.
Looks like you’re correct. The current location started reporting in 1951 and missed the record warm days from the 30’s and 1950. Highest at BWI before now was 75.
Nothing new for us. I went back as far as 1970 and found only 10 years where the high temperature for January did not reach 60 at DCA. Five of those years, the month topped out at 59, once at 58 and once at 57.
About a third of those years there were days that reached 70+.
Temps went above freezing here last hour. First time in over 210 hours. That period averaged 11° below normal during climatologically the coldest time of the year.
The HRRR runs all morning have been parking this narrow band over my yard this afternoon and sitting it there snowing itself out for a couple of hours.
Would be great if it’s on to something and my area can play catchup on accumulations.
