 Forecast for Sunday, December 21

Issued: Friday, December 19
Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron

Synoptic Discussion: "Again, no changes to forecast reasoning. Reinforcing surge of colder temperatures will settle in the state the remainder of the week.

"Other than a slight chance for ground winds exceeding the threshold during the final four minutes of 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."
