Forecast Discussion

Space Launch Delta 45

Overall, weather conditions will be quite favorable for Tuesday evening’s launch attempt. An area of high pressure centered off the Carolina coast will bring persistent easterly flow in the low levels for the first half of the week. The onshore flow, combined with seasonably dry air, will limit the coverage of afternoon convection near the Space Coast. The showers and thunderstorms that do develop will be focused on the west coast of the Florida peninsula on Tuesday. The combination of the dry air and relatively weak winds in the upper levels will also limit the ability of any anvil clouds to make it back towards the east coast. Thus, the only concern is the small risk of a brief coastal shower coming off the Atlantic waters, invoking a slight Cumulus Cloud Rule risk. Conditions will be similarly favorable for the backup window on Wednesday evening. Winds will shift slightly to the south, but will still have an easterly component that promotes the sea breeze front migrating well inland by the late afternoon and evening. The primary concern remains the low risk of a Cumulus Cloud Rule violation.
