Yesterday we broke the record high temperature with 68°. The previous record was 64° in 1984. Being December 28, that was alone enough to know that things would change abruptly.
By evening I was watching the barometric pressure nosedive. Here's what I saw on my phone from my Tempest station.
In fact, forecasters talked about a "bomb cyclone". The center of low pressure was forecast to be well NE of here, more over Michigan and Lake Huron, but still close enough (~ 400 miles) to have a major impact on our winds.
By the way, a bomb cyclone requires a pressure drop of 24 mb in 24 hours. I recorded a drop of 15.78 mb between 6 pm 12/27 and 6 pm 12/28. [30.015" (1016.42456 mb) to 29.549" (1000.64399 mb)]. So the term doesn't apply to my location.
Still the gradient in pressure caused the winds to howl and an Arctic front to nosedive the temperature.
Here's a wider view of the pressure drop. I went to bed before 10:30 pm but can't say I slept well. The winds kept buffeting the house and our storm windows rattled in their frames. The dog curled up tightly against me so I suspect she didn't manage a good night's sleep either.
Here's a look at how the temperature dropped. We had a high of 68.4° yesterday (4:15 pm) and this morning we were at 22.6° at 8:15 am. That's a 45.8° drop in exactly 16 hours.
The front dropped 0.47" of rain late yesterday. At the moment (8:30 am 12/29) we have snow flurries.
