Vehicle/Payload Atlas IIA (AC-143) / TDRS-I

Location: SLC 36A

Launch Weather Officer: Jim Sardonia, 45 WS Range Weather Operations

Synoptic Discussion:
Ideal weather conditions are expected for launch today as strong high
pressure aloft has brought dry and stable air into the local area. At
launch time, skies will be clear to partly cloudy and winds at the surface
will be easterly and light. These favorable weather conditions are expected
to remain in the area on Saturday and Sunday in the event of a 24 or 48-hour delay. The only slight concern for launch day will be the chance of an
isolated coastal rainshower developing over the waters east of the launch
pad and moving back towards Cape Canaveral.
