Forecast Discussion
Space Launch Delta 45
Forecast Discussion: Widespread showers and thunderstorms will continue over central Florida this evening as a frontal boundary progresses southward. Tomorrow, rain chances continue to be elevated as the boundary lingers to the south. Afternoon showers and thunderstorms are possible along the east coast, causing potential Cumulus Cloud Rule, Anvil Cloud Rule and Surface Electric Field Rule violations. A mid-level drying trend will continue for Thursday and Friday as high pressure builds and onshore flow settles in. Concerns will primarily be for the Cumulus Cloud Rule for both backup opportunities.
