A nearly full solar eclipse will be visible for a portion of the western United States coming up Sunday afternoon, May 20th. The map, courtesy of the National Weather Service shows the area that will see the nearly full eclipse highlighted in red.
However, only a partial eclipse (less than 50% of the sun covered) is expected in eastern Oklahoma and western Arkansas. The partial eclipse should start to become visible after 7PM Sunday night and will continue until the sun sets after 8PM.
Remember, to always use protection for your eyes if you plan to view to solar eclipse to avoid damaging your eyes. A complicating factor in trying to view the eclipse will be a cold front in the area Sunday night. The Euro weather model is showing a decent bit of cloud cover at 7PM Sunday night across eastern Oklahoma and parts of northwest Arkansas.
