It’s time for a new weekly weather quiz. Here is this week’s question. Major flooding occurred along the Northeast Coast of the U.S. in the summer of 1972 causing a 500-year flood in Elmira, New Your and other locations. What was the main cause of this flooding? You’ll get extra praise if you can explain a secondary cause for all of the rain that fell. Please place your answer as a comment after the forecasts on this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. Good luck
_______________
A high pressure ridge (shaded “Arch” shape over the Northwest) is moving away from us and a trough of low pressure (the shaded “U” shape along the coast) is moving in behind the ridge. A frontal system will move through Oregon. As the upper level low pressure trough migrates Eastward across Oregon the chance of rain will also increase for a while, then later in the week more high pressure returns the sunshine and warmer temperatures.

Advisories: NONE AT THIS TIME.
