Forecast Discussion

Space Launch Delta 45

Gradual warming back into the 80s will occur today as winds shift to the southwest in a pre-frontal environment. On Saturday, moisture will gradually increase across the peninsula as the weak frontal boundary slowly sags towards Central Florida, introducing rain with isolated thunderstorms into the forecast. On Sunday, the synoptic pattern remains sloppy as the weak boundary shifts to Central Florida. A weak area of low pressure is expected to form along the northern Gulf coast Sunday, which should help to tug the cold front through Central Florida by Monday morning, but not before the initial launch window. Agreement is not high between major model guidance of the timing of thickening of mid-level clouds or the onset of convection (if any), but the pattern is unsettled enough to warrant a POV of 60% for the initial launch window. For the backup launch window Monday, the cold front will push to South Florida. However, a secondary cold front set up behind it across North Florida will create lingering thick clouds across Central Florida, leading to a POV concern. Additionally, strong northerly winds behind the front will be present but the lack of convection should keep winds below threshold.
