AllSkyLAP over Northern High Plains

Working today as the Rapid City SD office. This area is under a slight risk, with convection expected to develop through a north/south corridor over the high plains.

Looking at AllSkyLAP stability indices to help evaluate the environment. The 4-pan image below shows  the north-south axis of instability over the High Plains, with CAPE (upper left) in the 1500-2000 J/kg range over SW SD. Upper right is lifted index and lower right is K index. The lower left panel shows whether the values are influenced by GOES data (blue/yellow) or if they are just GFS data (gray). Differences due to data type are noticeable in the CAPE image over western NE, but not so evident in the LI or K images. A.Cope
