KPLO - L-3 Days

A stagnant weather pattern will remain in place across Florida for another day as the western Atlantic ridge axis continues to meander across Central Florida and the Spaceport. Shower and storm chances will remain well below normal with temperatures above normal. Heading into midweek, a boundary riding over the top of the ridge across the southeastern US will weaken and suppress the ridge axis southwards. This will allow an increase in moisture along with better storm chances as the inland progress of the east coast sea breeze is halted closer to the coast. The ridge re-strengthens on Thursday as the boundary weakens, transitioning to very deep easterly flow. The east coast sea breeze will push quickly inland, along with any significant threat for storms beyond the early afternoon. A passing Atlantic shower or more developed cumulus can’t be ruled out in this pattern, but models suggest the threat is small for the early evening launch window on Thursday. A similar pattern will be in place for a backup launch attempt Friday evening.
