JSON Parsing in Ruby

I'm trying to parse the below from JSON (using the JSON gem) in Ruby:

"daily":{"summary":"Light rain today through Saturday, with temperatures rising to 88°F on Saturday.","icon":"rain","data":[{"time":1435464000,"precipProbability":0.99}]}

Currently what I have is this: forecast["daily"]["data"], but I want to get the precipProbability for time "1435464000". Any suggestion on how to complete my current JSON parsing "query"?
