OVERVIEW:
|
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

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