OVERVIEW:

2245 Z |
Running ClimoNear:
Mountain convection showing
increased organization and linearity. 2245Z, Base reflectivity

Begin Microphysical Scanning, Running
a test sequence - rain map plus two 170-deg sectors, centered on the mtn and other land convection: Resolution is a bit under 2 deg per elev step. This will at least get us two updates per
15-min cycle without giving up a lot of covg. Ocean
is bone dry right now, save for ... well, you know, all the water in it. 2315Z, Base reflectivity

0015
Z |
Manual
reset, bringing down top angles and improving vert res as nearby storms have collapsed. 0015Z, Base reflectivity
|
|
0030
Z |
Manual
reset. Continue to bring down top angle and improve vert
res. Strongest activity is coalescing far to our north, as well as due east. A
lot of good cells out there, high reflectivity with good phase shift, but no
MCS-like organization just yet.

0100
Z |
Manual
reset. Northern system continues to coalesce and organize. Eastern system
looks good too but is not as big. 0100Z, Base reflectivity
|
|
0135
Z |
New
development near 80 deg, 60 km from radar - not topped, raising upper angle
on last scan. 0130Z, Base reflectivity
|
|
0156
Z |
Eastern
convection looking pretty good. Northern convection also holding strong but
pretty far away. Raising upper angles at expense of vert
res. 0200Z, Base reflectivity

0215
Z |
End Microphysical Scanning, Switching
to ClimoNear: Northern and SE storms are getting too far apart to scan with this
sector anymore. 0215Z, Base reflectivity
