Weather Report for June 27, 2011

Rapid cloud formation over the area during the afternoon hinted that the monsoon is not many days away. Fortunately, there was no lighting this afternoon. There were a few strikes just south in Mexico and in western New Mexico. During the night, a new fire, possibly lightning caused, was noticed on the ridge line of the range about 50 miles N-NE of Mt. Bigelow. The clouds had nearly completely dissipated by sunset and the night was clear, warm, and nearly no breeze. The seeing was better than on the previous night at around 2 arcsec for most of the first half of the night. The seeing improved to 1.5 arcsec after midnight and there was brief period when it approached 1 arcsec.
