Issued: Tuesday, March 8
Launch Weather Officer: F. Clay Flinn, 45th Weather Squadron
Synoptic Discussion: "A cold front will pass through the Central peninsula this morning bringing cloudy conditions, isolated thunderstorms, rainshowers, and gusty winds from the West. Clearing is expected Tuesday afternoon/evening with high pressure moving in on Wednesday and decreasing winds.
"The cold front stalls in South Florida with a wave developing in the Gulf of Mexico and a broad trough across the peninsula Thursday morning and prevailing through the day. This will increase chances of thick clouds and isolated showers associated with the overrunning conditions. Temperatures are not expected to exceed user constraints with launch day temperatures ranging from the mid 40s in the morning to upper 50s near T-0. Winds are not expected to exceed user criteria.
"The main concern for launch day is violation of the Thick Cloud Rule associated with the overrunning conditions and isolated showers.
"In the event of a 24-hour delay, conditions improve with the trough East of the peninsula. However, a dry boundary will be in the Florida Panhandle Friday evening with a tightening pressure gradient. Winds will be gusting to 30 kts from the West. The main concern for a 24-hour delay are gusting winds associated with the tight pressure gradient."
