I am calling tonight's Sidewalk Astronomy at Robinson Preserve a "NO GO" due to the weather forecast.
It's rarely an easy decision because of our incredibly fickle weather, but the following seemed pretty likely:
• The last of today's showers would potentially extend up until around the time most of us would either be heading out and/or setting up our equipment.
• The odds of it being mostly overcast at least until 8:30 - 9:30 p.m. are fairly high.
• Once the skies do start to clear up nicely (which likely won't happen until almost 10:00 p.m.), there is a good chance that we'd be subject to unacceptably-windy conditions. I saw that there could be sustained 23 mph winds from the NW out there in the latter part of the evening.
