An upper level trough of low pressure (Shaded “U” shape with blue arrows) along with a frontal system will move in keeping the chance for rain with us 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 there may be a break in the cloud cover allowing a view of the moon. Remember it is safe to look directly at the Lunar Eclipse since it is reflected light from the sun.
