Forecast Discussion

Space Launch Delta 45

Forecast Discussion: The subtropical ridge axis remains in place over south Florida, providing high pressure and light southwesterly flow over Brevard County. Saharan dust advecting into the mid-levels will diminish afternoon thunderstorm coverage for the next few days. On Thursday morning, winds will be light and southwesterly, and a few offshore Atlantic showers are possible which could cause a small concern for the Cumulus Cloud Rule. Very similar conditions are expected for the backup day, as Saharan dust settles in the mid-levels and inhibits cumulus development.
