                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 We were able to open and abserver until around 22:20 or so, then the
cloud cover became too thick and stayed that way the remainder of the
night.
No precip as of about 05:00AM but it looked like the system was
finally making its way to us with radar returns just to our west.  We
gave up at 04:45 for the night.
