         ( It's now ~1900 hours Friday), the clock is still ending at 1700 Friday. Sorry to be grumpy about this.

      HI Chuck.

      I think we will all need some more experience with the Sky Clocks to see how well they work in practice.
      This morning and afternoon (Thursday), the forecast clock for Montebello went through today, all of tonight, tomorrow morning, and Friday to 5pm. That was enough to forecast tonight's observing conditions, and also to show a trend towards even clearer conditions tomorrow into late afternoon/early evening (Friday) .

      The information on the Canadian Meterological Center site says that CMC numerical models and 48 hour forecast sets are often made between 9 and 10 pm PDT at night, and between 9 and 10 am PDT in the morning. From Steve Sergeants email correspondence with Attilla Danko, it sounds like the schedule may be less predictable than this. However, I hope the updates will at least be regular enough that during the morning and afternoon, people will be able to see a recent prediction for that night's conditions at different locations.
