2223 Z

Scattered, moderate-strength convection firing over the SMO. Everything topped by 7.9 deg and is 90+ km out


2215Z, Base reflectivity


2245 Z

Begin Microphysical Scanning, Switching to MicroFar135 : Centered sector at 60 deg, RHI at 60 deg - on moderate-strength cell at 60 deg / 60 km.


2245, Base reflectivity


2254 Z

RHIs reveal a couple pixels of 60 dBZ aloft. Might qualify as an "intense, isolated storm".


2300 - 2355 Z

Taking RHIs through various cells in the NE quadrant - not very impressive.


2355 Z

Rotating PPI sector CCW to capture new growth to the NW. All echo present in S-Pol domain is being captured by sector scans - continuing with microphysical scanning.


0000Z, Base reflectivity


0005 Z

RHIs to near cell, 35 deg & 50 km. Most of the cells out there look basically the same, small with relatively intense cores up to frz level or so, and little anvil. By the time the anvil gets going the cell is drying up.


2254Z, GOES-10 Thermal IR


0045 Z

End Microphysical Scanning, Switching to ClimoFar: Scattered convection continues.
