0015	Switched to climofar. Cells we were watching nearby have weakened 
	substantially. Large anvil remnants remain and are visible in satellite 
	imagery. Scattered convection to the N/NE, no noticeable organization.

0100	Nitrogen delivered. Mini-tour given to 2 delivery personnel by Rob C – 
	they were interested in what we were doing and why we were here - they 
	live in La Cruz.

0246	Antenna stopped - restarted in ClimoFar mode. Will resynch at 0300.

0300	Dave A and Gustavo here.

0415	(approx)	Climoshallow - nothing out there.

1145	Some activity to the southeast moving in range >120km. Still below 5deg 
	elevation.

1200	Simona and Andrea here.

1228	Radar down to work on the Ka band. We discussed with Dave A before he left 
	and he thought this would be a good time for sorting out the radar. There 
	is a system that has been building to the southeast of the radar, at 200-
	150 km range over land. Still appears not particularly impressive but it 
	seems to be upgrowing and propagating to NW towards the radar. We are 
	keeping an eye on IR images.

1310	We did a surveillance scan in ClimoFar mode to check what the precip over 
	the SE looks like at this time. It has grown and propagated towards the 
	radar. Tops as high as 13km so we'll take the radar back up. We will run a 
	MicroFar135 sector. Just waiting for the engineers.

1329	Radar off.

1333	Sector scan in high PRF centered at 120deg, same for RHI. We will 
	synchronize it back to full 15 minutes at 1345.

1345	Resynching Far PPI135. With this PRF we may not be seeing as far as we 
	should but we seem to be getting most of the convection. We will keep an 
	eye on evolution and if things don't fit we'll switch to ClimoFar scan.

1355	Changed the RHI angle to 128 deg.

1429	RHI shows that this guy has a big anvil(!). We are still not sure if we're 
	getting all the convection, but we should be and it still seems as though 
	this is moving towards the radar.

1503	A convergence line has been persistent at ~40km over the ocean since we 
	started this shift. It appears that some new convection has been generated 
	along this line _130km range in the SE sector (~150 deg).

1521	Changed RHI to 107deg to capture strongest cell activity (~130km) >50dBZ 
	in core, large anvil to NW.

1600	Changed back to 720Hz PRF, ClimoFar mode. Large system to SE has weakened, 
	appears to be dissipating. Offshore convergence line flare-up weakened and 
	merged with larger system. Most active convective area (100-110deg, 80-
	100km) has ~40-50dBZ in core and appears to be weakening. ClimoFar should 
	capture the remainder of evolution.

1800	R/C at radar - no rain in gauge.

1815	Radar down for Ka-band work.

1852	Restarted SPOL on ClimoFar mode. Will resynch on the hour.

2030	A few weak cells ~30km east that we're not quite topping - may need to go 
	to nears, Other than this, just a few cells ~150km away. NE over favored 
	initiation region. 12Zaz sounding showing pronounced dry layer between 
	700-900mb. Same deal on Los Mochis 16:56 and. 2nd trip showing up over SMO 
	region.

2145	Echo area fraction increasing across NE sector - no organization, just 
	scattered cells.

2230	Bumping to ClimoNear to top cells nearby to our N.
