1000-500mb Thickness Maps and Model Contours

Unisys weather is investigating issues with both the 1000-500mb upper air thickness from the 00Z and 12Z soundings, as well as the color contours on the NAM and GFS SLP/Precip maps.

 

The issue with the upper air sounding contours may be due to a bad observation near Mexico City being ingested into the system, causing the mapping/contouring functionality to key in on this bad value.
