Weather Squadron

Vehicle/Payload: Delta II / Contour

Location: SLC 17A

Launch Weather Officer: Joel Tumbiolo

Synoptic Discussion:

Several factors will affect local weather conditions over next few days.
Combination of abundant moisture, afternoon heating, sea breeze development,
and a weak surface and upper level trough over central FL will result in
widespread afternoon and evening thunderstorms. In addition to remnant
cloud cover, showers and isolated thunderstorms may linger into the
overnight hours due to surface and upper level trough. Weak west to east
steering winds will result in all shower and thunderstorm activity moving
towards the eastern half of the FL peninsula. Main concern initially will
be local conditions at the time of MST Rollback. Afterwards, launch window
concerns will be remnant cloud cover and any lingering showers and
thunderstorms still in the vicinity.
