010522 -- Case Summary Flight Times: 2120 - 2439 No attenuation of 74C radar for this case. ATC and field mill-problems on plane. stratiform with embedded convection The Citation took off at 2128 and flew to an area of weak, but organized convection about 50 km to the SE of PAFB. This band of convection was moving from the WSW to ENE at 15 to 20 m/s and had been producing lightning for at least the last 2 hours. New, stronger cells tended to form on the NW end of this band. The convection was stratiform in character with several cells of embedded convection. The highest reflectivity was at 4 km, decreasing at 7 and then again at 10 km. Radar tops on the cells were 12 to 13 km. The electric fields decayed from ~40 kV/m to <3 kV/m
