Launch weather forecast
Posted: January 17, 2006

 Forecast for Wednesday, January 18

Issued: Tuesday, January 17
Launch Weather Officer: 45th Weather Squadron

Synoptic Discussion: "A cold front will continue to approach the Central peninsula through the evening hours with frontal passage expected during the early morning hours. Expect gusty winds through the evening and early morning hours associated with the frontal passage. After frontal passage, expect a clearing trend in the afternoon with a gradual decrease in wind speeds.

"The primary concerns for tomorrow's launch are thick clouds and ceilings associated with the timing uncertainly of the frontal passage.

"In the event of a 24 hour delay, the peninsula will be under high pressure with fair skies and Easterly winds at 12 to 18 knots. The primary concern for a 24 hour delay, although small, are low ceilings associated with Easterly flow."
