Issued: Thursday, July 5
Launch Weather Team: 45th Weather Squadron
Synoptic Discussion: "Widespread afternoon and evening showers and thunderstorms are expected through the weekend. Deep tropical moisture, the daily onset of the afternoon sea breeze, and favorable steering wind pattern will concentrate all activity on the eastern half of the Florida Peninsula. Conditions begin to improve early next week as the overall pattern changes.
"During the countdown, launch vehicle exposure constraints will be a concern as thunderstorm related precipitation and winds could exceed constraint limits.
"Main concerns during the launch window will be thunderstorms and associated clouds within 10 nautical miles of the launch vehicle flight path."
