Forecast for Sunday, August 3

Issued: Thursday, July 31 Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron Synoptic Discussion: "Currently, surface high pressure ridge axis continues to be located over the southern half of FL. This again is a pattern favorable for afternoon and evening showers and thunderstorms concentrating on the east coast of FL. A strong, upper level low pressure center over the Great Lakes region will act in keeping the surface ridge either over or south of the area for the next several days. "On Sunday, thunderstorms will develop along the east and west coast sea breezes. Thunderstorm outflow boundaries will trigger further development. All activity will move towards the N-NE. "Main concerns on launch day will be lightning and cloud cover associated with the showers and thunderstorms in the vicinity. Grounds winds will also be a concern."
