Forecast Discussion
Forecast Discussion: A surface ridge of high pressure extending from Bermuda through Central Florida will remain nearly stationary through tomorrow, resulting in mainly dry weather with a westward-moving seabreeze each afternoon. The ridge axis will weaken and get suppressed south as a front approaches the area Sunday, with this front moving across Central Florida on Monday. Generally favorable launch weather conditions are anticipated ahead of the front with a combination of shallow cumulus clouds and higher cirrus clouds locally early Sunday; however, the backup launch opportunity offers a significantly higher risk of unacceptable launch weather conditions with the front in the neighborhood and winds increasing immediately behind this boundary.
