Forecast for Saturday, June 28 at 11:56 p.m. EDT

Issued: Friday, June 27 Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron Synoptic Discussion: "Again, no changes to forecast reasoning. Deep moisture, which has been confined to south FL, will begin returning northward today. Weak frontal boundary, which passed to the south several days ago, will return northward. This boundary marks the transition to the deep moist air mass. Any low pressure development near the Yucatan will remain well to the west as it moves northward. By Saturday, once the moisture is in place, normal local triggers (sea breeze, day time heating etc.) with result in the return of showers and thunderstorms. "Main concern for the launch windows will be for remnant cloud cover associated with the showers and thunderstorms." Clouds: Scattered at 3,000 feet with 2/8ths sky coverage and tops at 6,000 feet; Broken at 8,000 feet with 5/8ths sky coverage and tops at 12,000 feet; and Broken at 25,000 feet with 6/8ths sky coverage and tops at 27,000 feet Visibility: 7 miles Launch Pad Winds: South-southeasterly from 160 degrees at 10 gusting to 15 knots Temperature: 76 to 78 degrees F Relative Humidity: 70 percent Weather: Mostly cloudy Probability of Violating Weather Constraints: 40 percent Concerns: Anvil Cloud Rule, Debris Cloud Rule, Thick Cloud Rule
