Right now weather.com is calling for showers (50% chance of precip) and 60 degrees at first pitch. From 20.00 onward they're calling for 0% chance of precip so, one way or the other, they should get tonight's Marlins finale in.
UPDATE at 10.15 - now calling for 'partly cloudy' and just 25% chance of precip at first pitch - despite the rather gloomy look of things outside my window right now, looks like this one's on.
