Issued: Thursday, December 18 Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron Synoptic Discussion: "No changes to forecast reasoning. Colder temperatures will settle in the state the remainder of the week. Reinforcing front that will pass through on Friday will keep the cold temperatures in place until early next week. "Other than a slight chance for low clouds an isolated coastal shower during the countdown late Saturday/early Sunday there are no real concerns. "Concern increases slightly into early next week as flow becomes more onshore, thus increasing the chance for clouds and showers."
