It&#8217;s an &#8216;atmospheric wave&#8217; which is formed by the atmosphere rising and falling like ripples in a pond. When the air rises above a threshold, its temperature drops below the point where visible moisture condenses. As it flows downward, it warms again and the moisture evaporates. <\/p>\n<p>This type of formation can occur in the lee side of mountains or ahead of an approaching front under the &#8216;right&#8217; conditions. This wave is one ahead of a front since there is rain in the forecast later this evening. <\/p>\n<p>Pilots of smaller aircraft are wary of areas where these form since turbulence can be severe to extreme. I can tell you from personal experience as a pilot that it is not much fun trying to keep the wings level in even moderate turbulence.<\/p>\n<p>UPDATE: The forecast was accurate &#8211; our chance of rain is now 100% at 7:50PM PDT.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Driving home this afternoon, I saw this cloud formation.
