                               ACTIVITY LOG
The telescope was not opened tonight due to heavy downpours, hail, lightning,
fog, high humidity, high winds, and overcast skies.
All of tonight was given to engineering.
The back half of the observing level near the stairs is flooded from the
downpours.(I have tried to mop it up)
At 23:10, I saw a small patch of clear sky, so I opened the cloud cam and began
getting the telescope ready to open.  As I went up to open the dome, I heard
rain on the tunnel roof.  After looking at the sky from the catwalk and seeing
how quickly the clouds and lightning were blowing in, I decided to wait.
The humidity then started to rise and a fog rolled in for the rest of the
evening keeping the humidity over 90%.
Forecast:(4:30am)
TODAY...VARIABLE CLOUDINESS WITH SCATTERED MAINLY AFTERNOON SHOWERS
AND THUNDERSTORMS. LOCALLY HEAVY DOWNPOURS AND GUSTY WINDS FROM
THUNDERSTORMS.
.TONIGHT...SCATTERED SHOWERS AND THUNDERSTORMS...MOST BEFORE
MIDNIGHT.
.THURSDAY...PARTLY CLOUDY. WIDELY SCATTERED AFTERNOON THUNDERSTORMS.
