to TAR are documented by PPI's at 0803 and 0903 in Fig. 49. The coverage of higher intensity echo
ob"iously increased over this time period and TAR recorded its highest precipitation rate between
0900 and 0930. The decrease in SL W depth noted at RRS and TAR, between 0900 and 10 15, was
likely in response to the increase in snowfall rate during this period.

FIgure 50, Radar PPI's taken at /007 (left) and / /03 (right) an 7 February /99-/.

The echo intensity at 1007 was similar to that at 0903, and reflects the generally higher precipitation
rate during this portion of the stonn. By 1103 the coverage of Level 50 echo had decreased
