We used this little tool on weatherunderground's website to gauge pretty accurately what the weather would be like for this past Sat.'s wedding.
While everyone, including me, was shivering Friday during rehearsals in 40 degree temps & rain, & on Sat. AM there was showers and clouds, my fiance (now husband) was sure there would be no rain& sunny skies. & sure enough by early afternoon, the clouds had broken, the sun came out, & the temps rose to ideal levels. It was as he had called it.
