AFWEX Status, 02 December 2000

Recap and Weather:
Mostly cloudy conditions at mid-day with chance of a 1km stratus deck over Oklahoma to become broken by evening. Scheduled for a DC-8 take-off time of 1945 CST with a flight plan similar to the 11/29 flight. At 1845 the flight was canceled due to overcast conditions at the CART site and thick cirrus moving in from the south-west. At the CART site, the low clouds became broken by 2030 CST and then dissipated by ~2200 CST. The cirrus moved in to cover most of northern Oklahoma with a base of ~9.5km and a 1.5 to 2km thickness and persisted throughout the night.
