Forecast Discussion

Space Launch Delta 45

Forecast Discussion: High pressure at the surface and aloft and abundant dry air will keep quiet conditions across the Spaceport to end the weekend. The pattern changes early in the week as the upper ridge breaks over the Florida Peninsula, with a passing upper-level disturbance bringing more upper-level moisture. This will lead to a thickening of the mid and upper-level cloud deck across the primary window early Monday morning, with the threat for associated Thick Cloud Layers Rule violations also seeing a modest increase with time across the window. The weakening and eastward shift of the ridge continues into the backup day on Tuesday, with a steady increase in moisture at all levels. There are some model discrepancies in how quickly moisture returns by Tuesday morning, but there is agreement for enough to see the return of at least an isolated onshore moving Atlantic shower threat in addition to the mid and high clouds. The threat for showers is expected to increase across the window with daytime heating and a prevailing onshore flow powered east coast sea breeze.
