The eclipse is finally at hand and hopefully you are able to see it wherever you may or may not have traveled to. While the eclipse at totality only lasts a few minutes, the shadow effects while the moon is partially blocking the sun lasts for an hour or two. The HRRR model includes special code to account for the change in received solar radiation during the eclipse. With instantaneous solar radiation output from the model at 15 minute resolution, the featured lapse nicely shows the impact of the eclipse. You may be wondering about the darkened areas already on the map. That is the effect of clouds reducing the solar radiation received at earth's surface.
