SCAN OVERVIEW:

 

0415 Z

Begin Microphysical Scanning, Switching to MicroFar90: Shortly after dissipation of multicellular storm to SE (Case 32), new cells popped up to the NE of S-Pol. The main storm is only a small decaying stratiform region so it seems valid to leave it out of the 90deg sector.

 

0415Z, Base reflectivity

 

0430 Z

Switched to microfar135 to capture the stratiform region within the sector, and to get some RHIs through the cells at 78 and 79 degrees

 

0430Z, Base reflectivity

 

0445 Z

This sequence took RHIs through 66 and 67degrees to slice the main cores.

 

0445Z, Base reflectivity

 

0515 Z

This sequence took RHIs through 73 and 74 degrees. The convection seems to be dying so will probably switch to climofar for the next sequence.

 

0515Z, Base reflectivity
