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 no frontal systems moving through Oregon, but one offshore Monday. The graphics for days 3-7   Tuesday through Saturday show a cold frontal system moving through the Pacific Northwest next Saturday.

Here is my new weekly weather quiz question. “What is a “Sling Psychometer?”

____________

Upper Level High Pressure will very slowly start to increase our temperatures. As it moves temperatures will slowly increase. The graphics for days 1-3  show a couple frontal systems east of moving through Oregon. The graphics for days 3-7   Saturday through Wednesday show a cold frontal system  sliding through the Pacific Northwest next Wednesday.

An Upper Level Low remains offshore and that means more onshore airflow keeping temperatures at a more normal level. As it moves temperatures will slowly increase. The graphics for days 1-3  show a couple frontal systems east of moving through Oregon. The graphics for days 3-7   Thursday through Monday show a cold frontal system approaching the Pacific Northwest Monday and Tuesday.
