Here is my new weekly weather quiz question. What does “ECMWF” stand for? Hint: it represents a very necessary weapon in the meteorologist’s weather forecasting arsenal. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.
An upper level high pressure ridge (shaded “Arch”shape) has brought sunshine to Oregon, but another upper level low that’s next in line will bring back the chance of rain for a while. A complex complex frontal system will return the stream of moisture pouring into Oregon and dropping snow levels below the passes by tomorrow bringing the “Spring Rain.” Spring officially begins with the “Vernal Equinox ” at 4:02 AM tomorrow.
