The sky is a lovely shade of blue, the temperature is a balmy 82 degrees, and the late afternoon light is beautiful as the first chords of Mendelssohn's "Wedding March" are struck and the bride steps down the grassy aisle.

By the time the sun sets, "I dos" have been exchanged and champagne is bubbling merrily in frosted glasses. It's a perfect outdoor wedding in perfect weather.

At least, that's what newly engaged Haley Mullins hopes her wedding will be. The 24-year-old Atlanta resident plans to get married outdoors at a country farm in Tallahassee next May. Thanks to the Weather Channel's Wedding Planner, her dream wedding is one weather estimate closer to becoming a reality.

"My main concern is the weather. Neither [my fiancé nor I] live in Tallahassee, so the planner is a convenient way to monitor the weather there," she said.

Like Mullins, more people are discovering the free wedding-weather planner at www.weather.com/weddings, which debuted last January.

"There are many great wedding planning sites, but no other sites have the depth we have in weather," said Randi Stipes, senior product manager for weather.com. "We combine historical weather data and climatology to make the most accurate predictions possible."

The site gives guidelines for long-term weather-planning decisions and true forecasts 10 days before the wedding. But it is more than just a simple weather predictor.

Some of the planner's features include "Set the Date," a tool that helps couples determine when and where to get married based on typical weather conditions; "My Wedding Weather," which allows people to create a customized page; "Planning Tools and Tips," which includes a sunset calculator, flower finder and beauty advice; and "Honeymoon and Destination Wedding Planner," which offers packing tips as well as weather outlooks.

The non-weather extras are a result of a partnership with the Knot, a leading wedding-planning site, so brides can be sure they're getting expert advice.

"We felt this content is essential to have ... so we could give brides a well-rounded wedding planning experience," Stipes said.

Brides have responded well to the site's attention to detail.

"I thought the planner was just going to be about the weather on the wedding day, but [it has] tons of stuff beyond weather. I was very impressed," Mullins said.

She also used the site to pick her Italian honeymoon destination, but her favorite feature right now is the planner's outdoor wedding tips.

"It listed things I didn't even think about, like covering candles so the wind doesn't blow them out, or using icing on the cake that won't melt in the sun," Mullins said.

"I wish this was around when I got married. I would have loved to have this tool available to me," Stipes said wistfully.

Since the site's launch, she has helped many friends, family members and co-workers use the planner, and has seen several of them make critical decisions about their weddings based on the planner's predictions.

However, she cautions brides against becoming too wedded to forecasts.

"Weather is one of those things you can't control. But you can certainly plan for it and give brides some reassurance and peace of mind so they know what to expect. That's our tagline — providing your wedding weather, for better or for worse."
