Here’s my weekly weather quiz question again. Scientists have determined that if we listen to the sound a particular creature makes we can determine the current ambient air temperature. What creature are they describing and how do you calculate the temperature? Please post your answer as a comment at the end of these forecasts. The first person to post the correct answer will win one week of free personalized weather forecasts tailored to your needs. Good luck.

Remember, the Vernal Equinox (the beginning of spring) takes place next Saturday March 20th at 10:32 AM.

_______________

The latest frontal system has been pushed onto the Oregon coast by low pressure aloft, but high pressure will take over and hold off any storms and return the sunshine that should last through Saturday, the first day of  spring. The next storm system will be setting up offshore by Saturday morning to bring the chance of rain back by Sunday.
