Forecast Discussion

Space Launch Delta 45

Forecast Discussion: No change to previous forecast. Moisture will increase today ahead of a quickly moving front that is expected to pass through the Space Coast tomorrow. Timing of the front looks to be near the opening of the window, with scattered showers and considerable cloudiness primarily from early morning hours through midday. Lingering showers and clouds will lead to higher chances of violation for the Cumulus Cloud and Thick Cloud Rules at the opening of the launch window. Behind the front skies will rapidly clear, so the only concern by the end of the window will be Liftoff Winds. For the backup day, high pressure builds back in once again, with no concerns for violations due to weather.
