Here is my weekly new weather quiz question. What is “Instability“?

A very strong Jet Stream flow from the northeast will be sending much cooler air to the Pacific Northwest. A frontal system will push through the Pacific Northwest from the northeast Saturday.

Here is my weekly weather quiz question for the last time. What is a “Hodograph“?  Here is the correct answer.  A Hodograph is a polar coordinate graph which shows the vertical wind profile of the lowest 7000 meters of the atmosphere. These plots are used to determine the advection patterns aloft, whether a thunderstorm will rotate, and the type of thunderstorms that you will likely see that day. I’ll have a new weekly weather quiz for you starting Monday.  The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.

An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) is still controlling our weather with northwest airflow, but about midweek an Upper Level Low Pressure Trough  (Shaded “U” shape with arrows on same graphic) will take over returning the wet weather pattern. The graphics for days 1-3 show a frontal system just offshore Tuesday. The graphics for days 3-7  show a frontal system  that pushes through  the Pacific Northwest Wednesday and another that will push through Oregon Thursday night into Friday. Yet another frontal system will be offshore by next Sunday.
