              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk, C.Gray
Evening started with high thin clouds and fair seeing. Humidity rapidly spiked, we toed the line, then humidity miraculously declined. Clouds began to thicken around midnight. We powered through the clouds until rain on the radar got too close for comfort, shortly after 05:00.
