Forecast Discussion
Forecast Discussion: The front that passed through the area over the weekend remains stalled across South Floridaand will gradually disintegrate over the next several days. Consequently, plentiful low-level moisture residing near and south of this boundary will continue to seep into the area as onshore flow remains robust, yielding the threat for intermittent showers. This activity is likely to be further enhanced with the daily afternoon passage of the seabreeze, where an isolated thunderstorm may also form. The bulk of organized shower activity should then retreat to the west side of the Florida peninsula each evening, with lingering showers also across the Atlantic. Thus, the main weather concerns for launch opportunities this week are the extent of showers and their associated clouds as well as continued breezy onshore winds.
