No takers for this week’s question. Here is my weekly weather quiz question for the last time. How do scientists forecast volcanic eruptions? Here is the correct answer. Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity and magnetic fields. Although not diagnostic individually, these techniques, when used in combination at well-monitored volcanoes, have resulted in successful predictions. At Pinatubo volcano (Philippines) in 1991, a successful forecast saved thousands of lives. For more on predicting volcanic eruptions go to The Global Vulcanism Program website. The USGS website also discusses these monitoring techniques in more detail. I’ll have a new weekly weather quiz question for you next Monday. 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.

A trough of low pressure (Shaded “U” shaped area with blue arrows) has moved over us sending waves of moisture our way. Today will be the “calm before the storm” so-to-speak because we are on the backside of the trough and a high pressure ridge (Shaded “Arch” shape) will take over for just a short time. The rain returns Sunday as a frontal system approaches. A frontal system will push through the Pacific Northwest Monday continuing a parade of storms that will increase the rain chances again.
