Launch weather forecast
Posted: November 3, 2004

Forecast for Friday, November 5

Issued: Wednesday, November 3
Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron
Synoptic Discussion: "No changes to forecast reasoning. Weak frontal boundary will slowly work its way into the Florida peninsula during the day on Thursday. Timing of frontal passage now is expected to occur after the launch window expires. Thin band of moisture associated with the actual front will be monitored as could be in the area during the launch window. Increasing clouds and a few showers can be expected with this band of moisture.
"Main concern for launch will be thick-layered cloud cover and any showers accompanying the front."
