Weather Report for September 7, 2010

Mt. Bigelow was hit by two separate storms during the afternoon that dropped an appreciable amount of rain. Conditions settled down after sunset, but despite the promising midnight IR weather image, debris clouds from the afternoon's widespread storms only cleared off of the mountain at 1-2am. Several targets were observed between then and morning twilight. The seeing was excellent at 1.0 arcsec. More thunderstorms are predicted for tomorrow.
