Here is my weekly weather quiz question. What is the “Backwater Effect?”  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 blue arrows) will slowly migrate across Oregon. That means we’ll slowly warm up a bit. The graphics for days 3-7 show the next major frontal system will move over the Pacific Northwest Sunday and Monday. So far, the 4th of July looks dry with temperatures in the mid 70s. That’s a bit below normal.

Here is my weekly weather quiz question for the last time. What are “Backing Winds?” Here is the correct answer. Backing Winds are winds which shift in a counterclockwise direction with time at a given location (e.g. from southerly to southeasterly), or change direction in a counterclockwise sense with height (e.g. westerly at the surface but becoming more southerly aloft). The opposite of veering winds. I’ll have a new weekly weather quiz question 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 blue arrows) that took over control of the Pacific Northwest weather bringing lots of sunshine and heat is slowly moving away to be replaced by a trough of low pressure (Shaded “U” shape with blue arrows). The graphics for days 1-3 shows a frontal system moving through Oregon cooling us down dramatically bringing in cooler and moist marine air. The graphics for days 3-7 show no major frontal systems over the Pacific Northwest through next Sunday.
