{Roberta & Jeff} A rainy engagement session

We scheduled a nice, relaxing engagement session with Roberta & Jeff in preparation of their wedding next May. There was rain in the forecast, but only 30% chance of showers starting at 10pm, no need to reschedule. Well, turns out the weather forecast wasn't 100% accurate and we got caught in a downpour! Roberta & Jeff were amazing however and we made the best of it! If it rains during the engagement session, does that mean it won't rain on their wedding day?
