Des Moines Airport Altimeter
When you get old like me, your bones and joints become the best predictor of the weather. The development of powerful storm system yesterday and today has dropped our surface pressure by around 0.7 inches of mercury (~ 24 millibars) in just over 24 hours. This is close to the "bombogenesis" criteria (24 mb in 24 hrs), which is just a cool sounding term to describe another cool sounding term, rapid cyclogenesis.

Voting:
Good = 12
Bad = 6
