Nice Example of ProbSevere Lead Time

Instability had increased in Hall county over the last hour with CAPE near 2500J/Kg, LI -6 to -7 and mid level lapse rate -7.5 to 8.  Ended up with a report of hail to 1.5" (unofficial) at 2314Z.

ProbHail jumped from 29% to over 70% in one update at 2242Z, and remained above 70% for the over thirty minutes leading up to the report.
