Check out my latest Eugene Daily News Weather Or Not column What’s the difference? It Can Be Important.

Here is my weekly weather quiz question for the last time. What is a “Cold Air Funnel“? Here is the correct answer. A Cold Air Funnel is a funnel cloud or (rarely) a small, relatively weak tornado that can develop from a small shower or thunderstorm when the air aloft is unusually cold (hence the name). They are much less violent than other types of tornadoes. 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 Low Pressure Trough (Shaded “U” shape with blue arrows) has moved closer taking over from the High Pressure and enhancing the chance for precipitation. The graphics for days days 1-3 show the frontal system that moved through Oregon Friday. The graphics for days 3-7 show the complex frontal systems starting to move toward and then across the Pacific Northwest Tuesday through next Thursday.

 Note: The overnight air quality in Eugene/Springfield and Oakridge has improved enough  for the Home Wood Heating Advisory to be lowered to Yellow.

An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) will move closer taking over from the High Pressure and enhancing the chance for precipitation. The graphics for days days 1-3 show the frontal system moving into the Pacific Northwest Friday. The graphics for days 3-7 show the parade of frontal systems starting to move toward and then across the Pacific Northwest Sunday through next Thursday.

 Note: The overnight air quality in Eugene/Springfield and Oakridge has become bad enough for a Red Home Wood Heating Advisory to be continued for yet one more day.

Here is my new weekly weather quiz question. What is a “Cold Air Funnel“? 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.

Upper Level High Pressure (Shaded “Arch” shape with blue arrows) is still in control producing sinking air the result of which is late night and early AM fog with freezing fog in many locations. An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) will move closer taking over for the High Pressure and enhancing the chance for precipitation. The graphics for days 3-7 show frontal systems starting to move toward and then across the Pacific Northwest Friday through next Tuesday.

 Note: The overnight air quality in Eugene/Springfield and Oakridge has become bad enough for a Red Home Wood Heating Advisory to be issued and continued for another day.
