HWT Acknowledges CAPE Weakness Over the Operational Area of WFO Raleigh

A large area of CAPE went well underforecast over much of the eastern half of the Raleigh CWA by the LAP Thermodynamic  Product due to the dependence on the GFS based capes.  The SPC Mesoanalysis at 16Z shows 1000 to 1500 J/kg Capes, with only a small area of CAPE values over 1000 J/kg denoted by the LAP (clear sky sampling).

Note: these values were 2 hours old compared to updated sources (e.g. RAP).
