Figure 1: On 9 September 2002 at 19:48 UTC, the radar reflectivity field shows
stratiform precipitation over southern Oklahom.

Figure 2: On 9 September 2002 at 19:48 UTC, the differential reflectivity field
shows nearly spherical droplets comprise the stratiform precipitation, with pockets
of more horizontally-oriented droplets colocated with areas of higher reflectivity (~40 dBZ).

Figure 3: On 9 September 2002 at 19:48 UTC, the specific differential phase field
indicates light rain with small areas of embedded slightly heavier precipitation, colocated
with the higher values of differential reflectivity and reflectivity.

Figure 4: On 9 September 2002 at 19:48 UTC, the hydrometeor classfication algorithm
identifies mostly stratiform precipitation, with a convective cell colocated with the area
of highest KDP, and areas of dry snow. Since the minimum surface temperature was 68F and the
troposphere is fairly warm (-6C at 500 mb), it is likely that most areas of dry snow are
likely misclassified (an exception may be the area near the Texas border, which is about
3,700 ft AGL).
