A plume of upper level moisture moving in from the Pacific will bring broken high clouds to the region late tonight into Wednesday. Unfortunately, this will hurt our chances of seeing the Flower Blood Moon Eclipse set to take place early Wednesday morning. Otherwise, fairly quiet weather is anticipated through Friday with typical breezy southwest winds and warm temperatures. A disturbance will pass to our north on Wednesday afternoon bringing a slight increase in winds, but gusts should top out around 25-30 mph.
