KRAH: Using 4 Panel Lap Data in Mesoscale Analysis


I found creating a 4-panel of LAP data (below) useful to our mesoscale analysis. While the data was 2 hours old, we were still able to get a feel for the convective environment in the KRAX CWA. This will be a useful tool to supplement SPC mesoanalysis data since it utilizes observations from GOES-16 satellite rather than fully relying on a model. The updates are also a little more frequent than what is found on SPC. Including the data type helped to indicate some of the gradients and the reason for the pixelling of some of the data. This can give forecaster more confidence when its indicating clear or cloudy versus soley on the GFS, which could add uncertainty into the data. Other variables in LAP such as K Index and Showalter are not something I typically use, so I left these out of the 4-panel.

At first glance, the scale/labeling on the Data Type were confusing. One potential change would be to have wording such as partial cloudy (for cloudy retrieval) or something along those lines to better differentiate the categories.

Note: the time of the data was 2 hours old during analysis.
