Cold Front Moving Through the Northeast U.S. Monday; Atmospheric River to Impact the Pacific Northwest Midweek

A strong atmospheric river is expected to move into the Pacific Northwest by midweek bringing a threat for moderate to heavy rainfall, gusty winds, and mountain snows for parts of Washington, Oregon, northern California, and the Sierra Nevada.

Perhaps you have heard of Crepuscular Rays...those rays of sunshine that poke through holes in cloud cover (as in the images below).

Did you know there also are Anti-Crepuscular Rays? This phenomena occurs when low-angled sunlight gets blocked by cloud cover...and would be visible on the opposite horizon. That is, sunrise rays would be visible in the western sky. A thunderstorm in the vicinity of Lake Cumberland this morning, caused just such a ray. It was visible on a webcam from WBKO over Scottsville, Kentucky. See that image below and also the animated gif showing a loop of those images. Below those images is a quick look of the storms that caused those rays from some different perspectives.

Tweet from Eddie Conner of what he saw of the storm and the radar imagery at the time.
