Please note that the radar was having hardware problems creating rapid and sporatic fluctuations in radar reflectivities. Radar reflectivities are not considered to be reliable for this case study.

Brief Cloud Synopsis

May 11, 1998:

Multiple cloud layers from surface to 8 km AGL (00:00-03:00). Lidar shows some regions of liquid in the lowest cloud. Deep precipitating cloud forms (tops at 8 km AGL) at 03:30 and continues until 24:00, gradually decreasing in intensity (radar reflectivity) but maintaining 6 km AGL tops. Mostly ice/mixed-phase system. Strong inversion which raises from 910 mb to 850 mb over the period.
