So, how cold was it?
It was 6 degrees outside my window in Cockeysville this morning. Now that's the kind of cold that gets your attention. With stiff winds to make it more miserable. Here is a quick check of the overnight lows and blows across Central Maryland.
Aberdeen: 10 degrees, winds 20 mph, gusts to 31
BWI: 9 degrees, winds 21 mph, gusts to 35
Frederick: 9 degrees, wind 24 mph, gusts to 30
Hagerstown: 6 degrees, winds to 29 mph, gusts to 39
Inner Harbor: 11 degrees (no wind data)
Martinsburg (for Cumberland): 8 degrees, winds 23, gusts to 32
The record low for BWI for Dec. 20 is 6 degrees, set in 1942. So, we were 4 degrees shy of a new record this morning. Wind chills, of course, were much more impressive - often in the single digits below zero and close to 30-minute frostbite territory at times. Here is a wind-chill chart.
