                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
 If it isn't high humidity, it's local radar activity. The heavy
 cloud cover of the early evening cleared somewhat around 11pm but
 the humidity was still way too high.
 2nd Half Observing Specialist: R.McMillan
 Heavy rain started around 02:00 and didn't let up until twilight.
