    dateMenu: Don't limit weather forecasts to the same day
    
    As we get closer to midnight, we show fewer forecasts than we could
    fit, or none at all. It makes more sense to continue the forecasts
    into the wee hours in that case, so only exclude past forecasts,
    but not ones from following days.
