The current cold snap began Dec. 27, but a high of 33 degrees Dec. 30 broke what would otherwise be a 12-day sub-freezing streak.
Temperatures remained below the freezing mark in Baltimore for eight straight days through Sunday, the region’s longest stretch of icy cold in 28 years.
But the streak ended Monday, with temperatures hit 33 degrees at Baltimore-Washington International Thurgood Marshall Airport.
The last time Baltimore spent so much time at or below 32 degrees was a 10-day stretch that ended on Christmas Day 1989, according to Jim Lee, meteorologist in charge at the National Weather Service’s Baltimore/Washington forecast office.
Before that, there was an eight-day streak of sub-freezing temperatures that ended Jan. 23, 1977, Lee said.
The current cold snap began Dec. 27, but a high of 33 degrees Dec. 30 broke what would otherwise be a 12-day sub-freezing streak. Baltimore temperatures constantly remained below freezing from Dec. 31 through Sunday.
The chill hit a crescendo early Sunday morning, when Baltimore-Washington International Thurgood Marshall Airport hit a record low of 1 degree. It was the coldest reading at BWI since a 1-degree low Feb. 20, 2015.
A gradual but eventually substantial warming is forecast this week. Highs are forecast in the mid-40s Tuesday and Wednesday, and into the mid-50s Thursday and Friday.
