The mercury here at The Sun is struggling to top the freezing mark today. Ten of the last 11 days have been below the seasonal norms at BWI-Marshall Airport. And 23 days in December were below the long-term averages, too. The average high for this date in Baltimore is 41. Our persistent cold weather comes to us courtesy of something called the Arctic Oscillation. You can read more on that, and La Nina, here.
But we're a long way from the record-cold days our parents and grandparents experienced. Thursday was the 99th anniversary of the day in 1912 when thermometers in Oakland, out in Garrett County, registered 40 degrees below zero. That was, and still is, the record-cold reading for the state.
The high reading in Baltimore that day (Jan. 13, 1912) was 11 degrees, still a record low maximum for the date. The next morning, the low in Baltimore was minus-2 degrees, also still a record for a Jan. 14.
