Eastern Range Operations 
Forecast Op Number:  F8451 PEGASUS - SORCE
Issued:  24 Jan 03
Valid:  25 Jan  03 / 2009 - 2109Z (1509 - 1609L)

Vehicle/Payload PEGASUS / SORCE
Location: Air Launch

Launch Weather Officer: Mike Jennings,
45 WS Range Weather Operations

Synoptic Discussion: 		
The strong cold front has exited the area and moved well south of the
Florida into Cuba.  A vigorous High Pressure Center drops into the 
South East U.S today inducing gusty surface winds and very cold 
temperatures over central Florida.  Temperatures dropping below 
freezing this morning and near freezing again on Saturday morning in 
the local area.  Weather on Saturday looks good for launch, with 
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 concern for launch day 
will be the chance of light with occasional moderate turbulence during 
L1011 climb out and at flight level (39 kft).
