An artifact in AllSky Products...

I was taking a first look at AllSky products this afternoon and put together a four-panel procedure. I expected to see some noise/sharp gradients in the data because differing pixel population methodology, but viewing a loop revealed an interesting artifact:



There appears to be an artifact in northern Arkansas that looks a little bit like a dinosaur head. This artifact is visible in parcel Lifted Index (to 500 mb), all PWAT products, and CAPE, but not in Total Totals, K Index, or Showalter Index fields. The artifact does not appear to be dependent on the Cloud Type field. Perhaps this artifact is associated with terrain in Arkansas but warrants further investigation. -Atlanta Braves
