Last night, I took a quick look at the models and saw that the forecast for Sunday had completely changed from 24 hours earlier. I updated the original post.
Sunday was originally forecast to be totally dry by several models. Last night’s NAM showed an upper air disturbance moving through from the northwest early.
Today, things have changed further and this area of showers and thunderstorms is just entering our area at 10 AM. Showers move through and showers end by 2-3 PM. Hazy sunshine with some clouds, warm and humid after the showers move through.
