<<...OLE_Obj...>> Eastern Range Operations Forecast Op Number: F8451 PEGASUS / SORCE Issued: 23 Jan 03 Valid: 25 Jan 03 Vehicle/Payload PEGASUS / SORCE Location: Air Launch Launch Weather Officer: Mike Jennings Synoptic Discussion: A strong cold front is expected to move through Cape Canaveral early Thursday bringing strong northerly winds and a chance of rainshowers. Very cold air will follow this front with the possibility of temperatures dropping below freezing on Friday and Saturday morning in the local area. Weather on Saturday looks good for launch, with light northerly winds at the Skid Strip for takeoff of the L1011. Skies are expected to be partly cloudy along the entire flight path of the L1011 prior to Pegasus Drop. A very strong Jet Stream aloft will provide a strong westerly wind at Flight level (39 kft) and a chance of light to moderate turbulence for the L1011. The only slight concern for launch day will be the chance of light with occasional moderate turbulence during L1011 climb out and at flight level (39 kft).
