Observations during a brief hail "storm" 6 May, 2002

Further Comments

- Lower atmosphere was quite unstable with billowing cumulous clouds
- The system that dropped the hail was much larger than other convective
  systems that were visible to the north and east and moved over us from the west
- The wind changed direction by about 90 degrees over the span of a few minutes
- The hailstones were up to about 5 mm in diameter with most of them about  3 mm 
- The shaded area on the plot indicates the approximate span of time when most 
  of the hail fell.  
- The event lasted about 15 minutes.  There was no significant rainfall during 
  this time (there wasn't enough total accumulation to trigger the  rain gauge)
