              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Started the day with snow, which tapered off by 18:00. Snow came and went, but no accumulation. Snow turned to intermittent rain as temperatures warmed in the night. Light drizzle on and off all night, in addition to high humidity. Observer called it quits by 04:30.  We did not open at all.
