Issued: Wednesday, August 10
Launch Weather Officer: F. Clay Flinn, 45th Weather Squadron
Synoptic Discussion: "The Bermuda High ridge axis continues to be suppressed to the South resulting in southwesterly steering flow. This pattern persists through Thursday's launch attempt. Steering level flow will favor late afternoon and evening thunderstorms along the East Coast. Anvil level steering flow has an easterly component on launch day resulting in a slight risk of anvil blow-off from Gulf Stream Thunderstorms. The overall flow pattern is favorable for a morning launch and results in a slight risk of morning coastal showers for launch day.
"The primary concerns for launch day are thick clouds and cumulus clouds associated with isolated coastal showers and anvil clouds associated with Gulf Stream thunderstorms."
