Here is my new weekly weather quiz question. This is a technical question. What has a “Sling Psychrometer” been used for in weather prediction? Please place your answer as a comment after the forecasts at the bottom of this page. The first person to post the correct answer will win a week of free weather personalized forecasts tailored to your needs. Good luck.

A weak cold front is falling apart as it moves through central and eastern Oregon. An upper level High Pressure ridge (“Arch” shaped shaded area) will build up and protect us from any storms for a while. Another large trough of low pressure (“U” shaded area over the ocean) will come in behind the ridge by late in the week. A cold front will be moving through the Pacific Northwest Friday bringing back more wet weather. Yet another frontal system will march through on Sunday.

Advisories: A HIGH SURF ADVISORY IS IN EFFECT UNTIL 9 PM TONIGHT FOR THE NORTH AND CENTRAL OREGON COAST. A HIGH SURF WARNING IS IN EFFECT UNTIL 11 PM TONIGHT FOR THE SOUTH CENTRAL AND SOUTH OREGON COAST.
