Mix of sun and cloud for Wednesday. Mostly sunny on Thursday with some pm clouds. Mix of sun and cloud on Friday with some convective activity that may bring some isolated showers. Time will tell. More on that as we get closer. Mix of sun and cloud Saturday. Ditto for Sunday. Cooler and wetter by early next week according to some long range models.
