If rain on your wedding day is good luck, Leonardo and Marissa Flores believe they must be extra lucky, with the 3.73 inches that fell Saturday.

The Floreses are one of record 13 Oklahoma couples who have won free engagement rings over the past rainy few weeks through BC Clark Jewelers’ Pray for Rain contest. Winners are entitled to a refund of up to $5,000 if it rains more than an inch on their wedding day.

The Floreses had planned an outdoor ceremony but were forced to move the wedding inside when the forecast called for rain. Some of couple’s wedding guests did not show up because of the weather.

“It all worked out in the end,” Marissa Flores said. “If it has to rain on your wedding day, it’s nice to get a little prize out of it.”
