Forecast for Sunday, September 25

Issued: Thursday, September 22 Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron Synoptic Discussion: "Hurricane Rita will continue to move westward towards the Texas gulf coast over the next couple of days. In the wake of Rita, surface and upper level high pressure centered well north of the state will build in resulting in a continuation of onshore flow. Weak tropical wave forecast to move across south Florida early next week may increase rain chances again on launch day. The possible development and evolution of this wave will be monitored over the next few days. "Launch window concerns will be westward moving cumulus clouds and showers over the near coastal waters." Clouds: Cumulus scattered at 3,000 feet and tops at 15,000 feet; Cirrus scattered at 25,000 feet and tops at 27,000 feet Visibility: 10 miles Launch Pad Winds: Easterly from 090 degrees at 10 gusting to 15 knots Temperature: 80 to 82 degrees F Relative Humidity: 75-80 percent Weather: Showers in the vicinity Probability of Violating Weather Constraints: 30 percent Concerns: Cumulus Cloud Rule, Precipitation
