Here is my new weekly weather quiz question. What is a “Tropical Storm Warning “?
An Upper Level High Pressure Ridge (“Arch” shape) starts clearing out the clouds and rain over Pacific Northwest. The graphics for days 1-3 show less frontal activity moving over the Pacific Northwest. The graphics for days 3-7 Saturday through Wednesday show less frontal activity continuing through the period until a cold front moves in next Tuesday followed by a complex frontal system Wednesday.
Note: Ski Report: Willamette Pass (closed Tuesdays and Wednesdays), Hoodoo (closed Tuesdays and Wednesdays), and Mt. Ashland (closed Tuesday and Wednesday) are all open for the ski season. Check their Web sites for specific mountain conditions and hours of operation.

Here is my weekly weather quiz question for the last time. What is a “Tornado Vortex Signature “? Here is the correct answer. A Tornado Vortex Signature is an image of a tornado on the Doppler radar screen that shows up as a small region of rapidly changing wind speeds inside a mesocyclone. The following velocity criteria is normally required for recognition: velocity difference between maximum inbound and outbound (shear) is greater than or equal to 90 knots at less than 30 nmi and is greater than or equal to 70 knots between 30 and 55 nmi. It shows up as a red upside down triangle on the Storm Relative Velocity Display. Existence of a TVS strongly increases the probability of tornado occurrence, but does not guarantee it; therefore, the feature triggering it must be examined closely by the radar operator. A TVS is not a visually observable feature.

An Upper Level High Pressure Ridge (“Arch” shape) is sending moisture to the Pacific Northwest.
