So what will the weather be this upcoming Saturday evening, March 21st?

As of Mar 19 — evening not defined yet.  Prediction for Saturday is for “a few flurries” with 1cm of snow and 5-10mm of rain.

As of late on Mar 20th — evening with “mixed precipitation” and the Clear Sky Clock has it too cloudy to forecast.  Will check in the morning, but not looking good for tomorrow evening.

As of 1pm Mar 21st — best we can expect is 70% cloud covered to completely overcast. Evening viewing cancelled.
