Starlink g8-5 - L-1 Day

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 towards the western half 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 chance of a low-topped shower coming off the Atlantic waters, invoking a slight Cumulus Cloud Rule risk. On Wednesday, the pattern begins to transition as a front dips into the Southestern US, pushing the ridge axis farther south and increasing moisture over Florida. Low level winds will remain southeasterly, but steering level flow and upper level winds will become more westerly. Because of these factors, the sea breeze collision will again occur well inland, but shower/storm coverage will likely be higher with an increased threat the storms and associated anvil clouds will be able to migrate back towards the east coast. However, after sunset, the weather violation risk will begin to decrease as convective activity wanes. The POV is higher at the opening of the window with the added risk of the Anvil Cloud Rules compared to Tuesday evening’s attempt.
