Here is my weekly weather quiz question for the last time. “What is a “Sling Psychometer?” Here is the correct answer.  A Sling Psychrometer is an instrument used to measure the water vapor content of the atmosphere in which wet and dry bulb thermometers are mounted on a frame connected to a handle at one end by means of a bearing or a length of chain. The psychrometer is whirled by hand to provide the necessary ventilation to evaporate water from the wet bulb.

An Upper Level Low Pressure Trough  is sliding down from Canada. The graphics for days 1-3  show a frontal system that will push through Monday followed by another wave Tuesday. The graphics for days 3-7   Wednesday through Sunday show a cold frontal system moving through the Pacific Northwest next Saturday.
