Space Launch Delta 45
Forecast Discussion: Much colder, drier air is filtering into Florida today behind a cold front that pushed through the region this morning. By tonight, northerly winds will significantly increase along the coast as the pressure gradient tightens. The wind speeds will become strong and will peak around midnight, before steadily decreasing throughout the day Tuesday as high pressure settles into the Southeast. The cold, dry air associated with the high will remain in place through most of the week, allowing for excellent launch weather conditions for both the primary and backup windows.
