An upper level low pressure trough (Shaded “U” shape with blue arrows) is controlling our weather now. A frontal system moved through the Pacific Northwest spreading rain throughout. Another frontal system will help keep us wet through the Easter weekend. The Full “Pink” Moon occurs at 5:06 AM Saturday and there will be a total Lunar Eclipse that will be visible in the Pacific Northwest just before dawn. By the look of it a thick cloud cover will be obscuring our view of the moon, but if the clouds do open it is safe to look directly at the Lunar Eclipse.
