0115	Switching to ClimoFar as activity is moving well to north. One except in 
	N-S line about 60 km west which we are currently topping < 14 deg looks 
	like ~6.5" in rain gauge.

0225	Line to our west slowly moving N but there are several cell clusters to S 
	of this line that all appear to be associated with some kind of boundary. 
	Tops 14-15 km, with dBZ cores 50-53; moderate phase shift 1-1.5deg/km but 
	limited ZDR columns.

0245	Going to ClimoNear to top line of cells to west.

0300	Dave Ahijevych & Arturo here.

0344	Watching north-south line of cells, 75 km west of S-Pol. Not quite as 
	linear as 30 min ago, as it has put down gust front boundaries and 2nd 
	generation cells are more spread out on the edges of the cold pool.

0420	A fine line met the storns from the east and they flared up - now 50 km to 
	the west of S-Pol.

0830	Some intense storms close by - hear thunder inside. Active areas needs to 
	narrow a little more to merit a sector scan.

0850	Switching to 960 Hz PRF. Arturo driving MicroNear135

0903	Surprising so much initiation over water.

0930	Line of strong cells right on the coastline 60-120 km NW of the radar.

1007	Shifted clock-wise a little bit to keepo them in the sector.

1017	Think I'll drop back to Climo 720 Hz PRF at 1028. Storms are too spread 
	out for sectors and the ones we are following up close have weakened 
	considerably.

1030	Started ClimoNear. Test pulse is contaminating the survey scan.

1032	Restarted ClimoNear. Removed 26.4deg for a while to catch up.

From 0900-1030 ran with high PRF.

1045	Bumped off 0deg scan and resynced start of ClimoNear with 1045. Also 
	reinserted 26.4deg to the angle list.

1049	Blob of precip. 80 km to the east.

1138	Lots of near-coastal oceanic development. Shallow stratiform mostly.

1200	Brenda Dolan, Gustavo Pereira and Simona Bordoni taking over
	Still running ClimoNear.

1237	Brenda emptied the rain-gauge, which had ~ 1 cm. We are guessing that this 
	was already reported yesterday by Rob.

1240	Line of convective cells has been developing to the south of S-Pol over 
	ocean. at 1230, it appeared pretty coherent; core reflectivities in the ~ 
	50 dBZ range; there is another broad region of convective activity to NW 
	of S-Pol.

1413	The line of convective cells to South has spread out, being now less 
	linear that what it was before. Another line of convective cells is now 
	observed to the west of S-Pol, NW-SE oriented, at ~80-120 km range, 
	topping at ~ 12km.

1438	Sprinkling outside...

1605	We have been scanning in ClimoNear up to now. We have been keeping an eye 
	on the system over the ocean to SW. It appears as a persistent and linear 
	MCS; the line ot oriented parallel to the coast. It appears to be 
	propagating towards the coast, then dissipates and the line of cells 
	regenerate more or less in the same position (which is ~ 80-100 km to SW, 
	parallel to the coast). Stratiform region is as close as 50 km. 
	Precipitation does not appear to be significant. 

1615	Because all convective cores in the line appear to le ~ 100 km from the 
	coast, we decided to switch to ClimoFar, not to loose vertical resolution 
	on the far guys.

1730	The organized structure over the ocean is beginning to fall apart. However 
	a new cell is building SE of S-POl that we are going to keep an eye on.

l739	Reflectivity in small cell now above 50 dBZ. Made some images for web.

1800	Rob and Andrea here.

1825	Switching to Ka-band on. Both Ka and S-band will be operating at 1000 PRF. 
	Because some activity started developing to the N of S-Pol and may be 
	getting on top of NOAA profiler, we decided to to a sector scan, 
	MicroNear135, centered at 0 deg. The rhi will be centered at 30deg. We 
	will start at 1830.

1830	We started the Microscan, but the Ka band is not on yet.

1840	Ka band on.

1910	Started to sprinkle lightly at SPol.

1920	N sector still appears to have most of the action for new convection. 
	however few cells S-SE need to be watched - most of intense cells in N 
	sector are > 90 km range - too far for Ka band.

2000	Ka-band off. Switched to 720 Hz PRF to run climo scans. Running ClimoNear 
	to capture cell approx 42 km/2deg.

2035-	Visited by NWS (Mexico) Director, Jose Meitin (NAME ops director) 
2145	Fabian (Altair), spoke with S-Pol staff & took pictures.

2200	Switched to climofar mode. There is still convection within 30-40 km of S-
	Pol but it would be captured well enough using far mode. Generalized 
	convective activity spread out over SMO, but there appears to be 
	convection focused along line running parallel to shoreline (~20-30 km 
	inland).
