Forecast Discussion

Space Launch Delta 45

A large area of high pressure over the eastern US will continue building southwards across the Florida peninsula through the remainder of the day. The tighter pressure gradient will bring an increase in onshore flow, which will continue into Wednesday along with more low level cloud cover. There will be a small chance for an Atlantic shower going into Wednesday, but the concern for the afternoon launch window remains very low. The main threat during the window will be Cumulus Clouds. There will be little change in the pattern into Thursday, with breezy onshore flow and increasing moisture bringing a few more Atlantic showers. The threat for showers will remain low, but the increase in cloud cover will bring a corresponding increase in the threat for Cumulus Cloud Rule violations.
