Here is my weekly weather quiz question. What is a “Jetty? 

_________________

An Upper Level Low Pressure Trough (“U” shape) is approaching the Pacific Northwest. The graphics for days 1-3 show no frontal systems moving our way. The graphics for days 3-7 show an increase in complex frontal systems moving our way Friday through next Tuesday continuing the rain chances.

NOTE: SPRING OFFICIALLY BEGAN AT 2:24 PM MONDAY WITH THE VERNAL EQUINOX. We’re on the Spring roller coaster ride. Sunshine one day, then rain, repeat.
