              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with some intense thuderstorms right around dusk.  Clouds and scattered showers persisted until around 01:00. It looked like it was going to be safe to open, but then scattered storms began appearing on the radar, and some light rain came around 02:00, keeping up closed. Afterwards, suckerholes continued to tease us even as the radar showed rain all around.  At 0400 we called it.
