(* means a trouble report has been issued or appended to)
The telescope was not open tonight due to snow and ice on the roof of the
enclosure.  Also, we had overcast skies and flurries throughout the evening,
with high humidity.  The snow fall from last evening was roughly 13-15 inches.
I spent 7-8 hours trying to complete the snow removal, but the snow was just
too heavy and too abundant to finish it off.  There is about 6-8 inches of new
snow on the enclosure roof.
Latest forecast:
.TODAY...COLD. MOSTLY CLOUDY WITH SCATTERED SNOW SHOWERS THIS
MORNING. ANOTHER INCH OR TWO OF NEW SNOW POSSIBLE ABOVE 6500 FEET.
DECREASING CLOUDINESS THIS AFTERNOON. NORTH WINDS 10-15 MPH.
.TONIGHT...CLEAR AND QUITE COLD.
.SATURDAY...FAIR SKIES WITH MODERATING TEMPERATURES.
.SUNDAY...FAIR SKIES.
