Launch weather forecast
Posted: October 8, 2007

 Forecast for Wednesday, October 10

Issued: Monday, October 8
Launch Weather Officer: 45th Weather Squadron

Synoptic Discussion: "High pressure to the North and a broad area of low pressure to the South will result in winds gusting in the mid 20s (230 feet) and isolated coastal showers today.

"For MLP roll on Tuesday, high pressure remains in place with a reducing pressure gradient. Winds should be gusting in the upper teens to near 20 kts with isolated coastal showers.

"On launch day, high pressure remains in place with an encroaching frontal boundary in the Southeast. Winds are Eastnortheasterly gusting in the upper teens. Isolated coastal showers persist with the continued Easterly flow.

"The primary concerns for launch day are cumulus clouds and disturbed weather associated with an isolated shower coming in from the Atlantic.

"In the event of a 24 hour delay, a frontal boundary in the big bend area and low pressure to the South results in a slight increase in cloud cover and isolated showers. The primary concern for a 24 hour delay are disturbed weather, thick cloud, and cumulus clouds."

Clouds: Cumulus scattered at 2,500 feet with tops at 15,000 feet; and Cirrus scattered at 24,000 feet with tops at 26,000 feet
