Here is my weekly weather quiz question for the last time. What is “Latent Heat Flux?” Here is the correct answer. Latent Heat Flux is the flux of heat from the earth’s surface to the atmosphere that is associated with evaporation or condensation of water vapor at the surface; a component of the surface energy budget. I’ll have a new weekly weather quiz question for you starting 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 large upper level low (Shaded U shape with blue arrows) continues to send frontal systems at us. A frontal system, moved through the Pacific Northwest spreading more rain across the area and even prompted a severe thunderstorm warning for Northeastern Benton County, North Central Lane County, Western Linn County, Southwestern Marion County, and Southeastern Polk County at 11 am lasting for about a half an hour. Look to the West on the previous graphic and you’ll see the next frontal system moving in. A parade of increasingly  stronger storms like this frontal system that will slide into Oregon Tuesday. We will see another frontal system like this one shown pushing onto the coast next Thursday. Willamette Pass, Hoodoo and Mt. Ashland are all open with great ski conditions. Check their websites for updates.

A large upper level low (Shaded U shape with blue arrows) continues to send frontal systems at us. A weak frontal system moves into the Pacific Northwest producing clouds and some rain. A parade of increasingly  stronger storms like this frontal system will move in Friday adding to the chance of rain. The storms will be spaced about 24 hours apart. Another frontal system pushes into Oregon Sunday into Monday. Willamette Pass, Hoodoo and Mt. Ashland are all open with great ski conditions. Check their websites for updates.
