Some additional tidbits for severe weather. Please note these are conclusions from various presentations and not my own thoughts.
1.) Mesonets that capture solar irradiance (W/m^2) should visualize their data. Gradients in solar irradiance can illustrate CAPE gradients that will support convective initiation. NOTE: The Maryland mesonet will show this once stations are deployed.
2.) The SPC HREF performs poorly with mid level cloud erosion times in cool weather severe episodes, especially in the Mid Atlantic and Northeast. The cause remains unknown and warrants further study. If the SPC HREF shows an area breaking out into the warm sector, and does not have support from the rest of the CAMS, consider disregarding the SPC HREF.
3.) When forecasting big hail events, the 12z RAOB closest to your location can be helpful in identifying an EML. This is especially true when comparing to special 18z RAOB because the 12z data will feature a comparatively cool surface temperature which lets a forecaster "see" the fingerprint of an EML advecting from Texas or the Mexico highlands.
