She's Gonna Blow

Barometric Pressure

My neices and nephews gave me a weather station for Christmas 2000. The Harris family has a long history of fascination with weather. It took me a while to decide where to mount the station. I finally settled on the back (south) wall of the family room, which gives poor temperature readings (heat from the outside), but is otherwise a very convenient place to see it and read the instruments.

Very high barometric pressure - unusual during winter

On the morning of February 25th, I looked at the barometer and was amazed at how high it was. "Normal" pressure is 1013 millibars; as the photo shows, the barometer was reading 1052. The extraordinary aspect of this is that summer is the time when we have high pressure; commonly a large high pressure system sits over the western USA, and gives us the glorious sunny days we long for so much. But this was in winter!
