Forecast Discussion

Space Launch Delta 45

No significant changes to the forecast as the high pressure area over the Atlantic Ocean has started to retreat east. In addition, the northern portions of a frontal system are pushing off the Eastern Seaboard today, as the front’s tail moves over the Florida Panhandle. Southerly winds will keep the temperatures elevated in Central Florida and allow daily sea breeze interactions to produce isolated showers and thunderstorms each afternoon and evening. On Tuesday and Wednesday, the remnants of the boundary will stall mostly north of the Space Coast, but add ingredients to enhance the shower and thunderstorm coverage and intensity. The primary weather concerns for Wednesday morning are the Cumulus and Anvil Cloud Rules associated with lingering convection along the boundary. High pressure will begin to build back into the area on Wednesday and Thursday, returning Central Florida to the daily cycle of sea breeze interaction. The primary weather concern for Thursday morning is the Cumulus Cloud Rule.
