HGX First Warning of the Day

Using the PGLM, ProbSevere and KHGX all-tilts, warning decision was made for large hail and wind.

The PGHG flash densities spiked at 66/min at 1906z

Meanwhile, the ProbSevere also was increasing. After remaining steady at 20%, it jumped to 80 percent then maxed out around 90 percent.

On the other CAVE perspective, the KHGX radar data showed a weak hail spike at the 5.1 degree slice. The Z/CC showed this fairly well.

The combination of the ProbSevere, PGLM lightning densities and the radar data provided enough confidence to go with a warning.
