Cold Front: February 22, 2017

A cold front swept through Utah yesterday evening. You can see it move north to south at the locations plotted below.
  • Blue = Salt Lake Airport
  • Green = Point of the Mountain
  • Red = Orem
  • Orange = Spanish Fork


Nearly a 30 degree drop in temperature is quite impressive for a cold front. It rain most the evening and turned to snow overnight mostly impacting Utah County


A look at the wind speed and direction:

Calibrated my Pressure Sensor

The pressure sensor at UKBKB Spanish Fork (aka EW2355 Spanish Fork), has read wrong since I installed the weather station several years ago. I finally borrowed a Kestrel 4500 from work to apply a correction to my pressure sensor. As a result, I reduced the pressure reading on my Davis Vantage Pro 2 by 4 hPa.

You can see the change in the MesoWest time series plot when pressure decreased 400 Pascals:
