9. Summary
Jan. 19 drizzle yielded measurable precipitation, and lasted several hours accompanied by onshore flow and high 500 mb heights.
Radar sensitivity limited to detecting weak drizzle echoes for ranges less than 40 km.
Scans at higher elevations (CAPPI, Echo tops, XSI) failed to detect drizzle.
Small drop size distribution yields low estimates for radar-derived accumulations.
