Second Lowest Pressure Reading in December for Detroit

Second Lowest Pressure Reading in December for Detroit -12/10/09  

The strong low pressure system that moved through the Great Lakes Tuesday into Wednesday, brought the second lowest pressure reading ever recorded at Detroit for the month of December. The lowest pressure attained at Detroit Metro Airport during the storm was 28.98" /981.3 MB/ on Wednesday, December 9th.  It is impressive that it even made second on the list since to low tracked well west of Southeast Lower Michigan (basically from Chicago, northeast through northern Lower Michigan into Lake Huron). Closer to the storm’s center, the pressure fell to 28.85” at Saginaw.

Checking back through the lowest pressure readings for December in Detroit shows that in 1968, the barometric pressure dropped to the record low for December of 28.87”. Therefore, the barometric pressure fell 0.11 hundreds lower in the 1968 storm than in our recent storm.  The lowest pressure reading ever recorded at Detroit was during the monstrous storm, “ Blizzard of 1978”, when the pressure cratered to 28.34” on January 26th 1978.
