Time (UTC)	Event
1038	Data collection began.
1107	Echoes oriented in a N-S line appear to the NW of the radar approx. 40 km away. Reflectivity values are as high as 35-40 dBZ.
1110	I noticed the Radiate On light no longer illuminates on the transmitter panel. However, the Radiate Off light illuminates properly in the sector that is blanked out.
1127	Prefrontal popcorn convection appears to the NNW of the radar while a more substantial N-S oriented line is situated on the western periphery of the radar coverage. Is this latter feature the front?
1426	Light to moderate rain falling at radar site. Very clear bright band evident at higher elevation angles with reflectivity values exceeding 50 dBZ.
1550	Echo intensities and areal coverage have weakened. Conditions at the radar site are light rain and fog.
1608	Melting layer signature is now difficult to identify looking at higher elevation angles. Earlier in the event, the circular artifact around the radar was obvious.
1651	Isolated cells showing up to the N and W of radar. Rain at the radar site has become very light. Suspect this popcorn convection will persist for a few more hours.
17:00	Good morning foresthill.
18:15	Isolated, light cells persist from site to 60km NE. Very light rain at site.
19:00	Same as above, but cells extend slightly SW from site, and light drizzle here.
19:44	Still have cells out to 50km NE, even lighter now, some up to ~20 dbz. No precip at site at moment. Quite bright, but still overcast.
20:00	Data collection stopping.
