An upper air high pressure ridge (“arch” shape) has cleared out the clouds, but we’ll go back to wet as a low pressure trough approaches and a frontal system returns the rain late tonight and Sunday. More frontal systems will move in next week so it looks like the Spring rains will continue. Sorry, but you’ll need an umbrella or a coat to protect your Easter outfit for “Sunrise Services” and the rest of the day Easter Sunday. It might be a good idea to have Easter egg hunts indoors if possible.
