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

____________

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

Here is my weekly weather quiz question for the last time. “What is the “Showalter Index?” Here is the correct answer. The Showalter Index(Abbrev. SWI) – is a stability index used to determine thunderstorm potential. The SWI is calculated by lifting an air parcel adiabatically from 850 mb to 500 mb. The algebraic difference between the air parcel and the environmental temperature at 500 mb represents the SWI. It is especially useful when you have a shallow cool airmass below 850 mb concealing greater convective potential aloft. However, the SWI will underestimate the convective potential for cool layers extending above 850 mb. It also does not take in account diurnal heating or moisture below 850 mb. As a result, one must be very careful when using this index.

____________

An Upper Level Low remains offshore and that means more onshore airflow. As it moves temperatures will slowly increase. The graphics for days 1-3  show a frontal system sliding into Oregon Monday. The graphics for days 3-7   Wednesday through Sunday show a cold frontal system sliding through the Pacific Northwest Wednesday.

Here is my weekly weather quiz question for the last time. “What is the “Showalter Index?” Here is the correct answer. The Showalter Index(Abbrev. SWI) – is a stability index used to determine thunderstorm potential. The SWI is calculated by lifting an air parcel adiabatically from 850 mb to 500 mb. The algebraic difference between the air parcel and the environmental temperature at 500 mb represents the SWI. It is especially useful when you have a shallow cool airmass below 850 mb concealing greater convective potential aloft. However, the SWI will underestimate the convective potential for cool layers extending above 850 mb. It also does not take in account diurnal heating or moisture below 850 mb. As a result, one must be very careful when using this index.

An Upper Level Low is moving away from us but still producing sunshine with high temperatures in the 90s. The graphics for days 1-3  show a frontal system sliding into Oregon Friday. The graphics for days 3-7   Tuesday through Saturday show a cold frontal system sliding into the Pacific Northwest  Monday and another on Wednesday.
