CRS-31 - L-1 Day

Surface high pressure currently situated across the Northeast U.S. will shift east out into the northwestern Atlantic over the next few days, with a tropical cyclone likely developing across the Caribbean Sea. The resultant strengthening and deepening onshore flow locally will support intermittent showers rolling off the Atlantic and onto the Spaceport. Atmospheric moisture within this flow is likely to substantially increase going into midweek, yielding a greater concentration of showers and higher threat for launch violations on the backup opportunities. However, winds will remain elevated through the week, and gusts associated with any showers will further exacerbate these winds. Consequently, the probability of violation for weather constraints is somewhat greater than November climatology for the primary launch day, and much higher than normal for the backup launch opportunities.
