NASA Crew-1 - L-1 Day

North-northeasterly flow will continue to bring onshore moving showers off and on through much of the day into the evening. By late tonight, a diffuse frontal boundary across South Florida will lift back into Central Florida and the Spaceport. This will bring better rain chances into Sunday as this boundary stalls out across the region ahead of another frontal system moving into the southeastern US. This will bring scattered showers through the day, continuing into the primary launch window Sunday evening. The primary launch weather concerns will be the cumulus clouds and precipitation associated with this activity, along with electric fields from any more robust showers. The system moving over the southeastern US will leave another front stuck across the Florida peninsula to start the upcoming week, with a strong area of high pressure pushing across the eastern third of the country clearing it through Central Florida by Tuesday. This will setup a relatively stable atmosphere that will be in place for the remainder of the week with gusty northeasterly winds. The primary weather concern for the delay launch window mid-week will be the gusty winds and scattered cumulus clouds.
