Weather Report for March 1, 2017

Rain and snow showers hit the observatory off and on during the day as the main storm front came through southern Arizona. There was, however, much less precipitation than forecast. The mountain top was in clouds until just before midnight. The sky cleared rapidly, but the humidity stayed too high to open the dome until after 0230 local time. Several blazars were observed until the end of the night in clear skies and seeing of 1.5-2 arcsec.
