Issued: Monday, December 13
Launch Weather Officer: F. Clay Flinn, 45th Weather Squadron
Synoptic Discussion: "High pressure should dominate the Florida peninsula throughout the week. A dry cold front will approach the peninsula Monday evening and reinforce the cold air from the weekend. Winds will be from the Northwest through most of the week with a gradual trend from the North to North Northeast towards the latter part of the week. With Northerly to North Northeasterly flow on Friday, we will likely have a low broken deck of clouds blowing in from the Atlantic and occasional drizzle. A trough of lower pressure is expected to develop off the East Coast late Thursday through Friday which may result in isolated coastal showers.
"The main weather concern on launch day will be a nontransparent, thick cloud layer. These conditions persist into Saturday with the aforementioned disturbance off the Florida peninsula. Winds are not expected to approach ops constraints."
