L-3 Day Weather Forecast for STS-35
Conditions expected on Sunday, 12/2/90
Synopsis: High pressure centered over the central United States
with a stationary front just north of KSC are expected to be the
dominant weather features influencing weather conditions in the
Cape Canaveral vicinity. The exact position of the frontal
boundry will be better known on Saturday. The main concern is
possible occasional ceilings below 8,000 feet. The low pressure
system currently located south of Cuba is not expected to be a
factor.
Between 1:28 a.m. and 3:58 a.m. on Sunday morning conditions are
forecast to be:
Clouds: 4,000-7,000 scattered stratocumulus
8,000-11,000 scattered altocumulus
28,000-33,000 scattered cirrus
Visibility: 7+ miles
Wind-Pad 39B: ENE/10-16 knots
Temperature: 62 degrees
Dewpoint: 60 degrees
Humidity: 92%
Precipitation: slight chance of showers
Probability of tanking constraint violation on Saturday: 10%
Probabilities of launch weather criteria violation: Sunday 30%
Monday 30%
Tuesday 40%
