0031	Convection continues to sink SSE along foothills. Still 30dBZ at 13.8deg so no climofar yet

0117	Status quo pretty much. System continues to slide slowly Sward. Startiform area has expanded; still not huge coverage given intensity and duration of convection. Will have to watch for stratiform rain at the profiler this evening.

0121	Anvil is spreading NWward from the line of convection over us -> stratiform rain may develop if these ice particles ever fall.

0134	Stratiform rain (~25dBZ) is breaking out near the profiler site. Will run profiler scan next volume. Can see nice brightband on upper elevation scans.

0145	Running profiler scan - nice bright band in RHI's +25dBz rain in PPI's.

0200	Back to ClimoNear - 0.8deg scan corrupted? Pie shaped again, anvil rain fairly widespread to north.

0248	Light rain at SPOL, stratiform coverage diminishing to NE.  Bright band echo in 1.3deg scan impressive to NNE. MCS may be approaching from SE.

0300	Gustavo here

0400	A few cells have developed 150km NNW of S-POL and attained reflectivities of up to 55dBz in their cores. Otherwise, all echoes are centered over land, dissipating and moving from SE to NW.

0600	All echoes topped out at 13.8deg, switched to climo far.  The convective cells present at 04 UTC are still intense. Everything else decaying.

0630	Convective cells to NNW still developing, moving opposite to the flow of other cells.  Located ~120km from S-Pol, somewhat a linear cluster.  Part of this line is now over water.

0730	The line of convective cells has dissipated.  All echoes over land are decaying.  One cluster has entered S-Pol range at 315deg and is propagating along the coastline and over the water.

0945	Coastal cluster decaying.  All echoes below 5.5deg.  Switched to ClimoShallow.

1000	A convective cell developed over the Gulf, WNW of S-Pol. 

1100	The maritime convective cell is decaying and generating

1200	Sarah here (land breeze fine line visible)

1205	Some weak echoes up to ~20dBz seen NE of radar w/in 60km range...will switch to ClimoFar to try to top them.

1215	Switched to ClimeFar, and noticed weak new echo ~15km range east of radar, as well as some to SE w/in 60 km range.  The echo ~15km range is non-precipitation stratus (based on visual).

1237	Cells to NE are dying, may switch back to climoShallow.

1245	Back to ClimoShallow.  Land breeze fine line has dissipated.

1300-1500ish	A few cells along northern end of old fine line growing and decaying.

~1415	Scans got off time somehow...first noticed it in Zebra & though a few scans just didn't transfer over b/c by 1418 they were showing up...but by 1430 the scan was on 4.2deg let sequence finish.

1432	Restarted Climo-shallow 2 min late due to problem noted above.

1445	restarted scan sequence to resync properly

1515	Ran rain map and stopped for 15 min solar scan

1530	Restarted ClimoShallow, only one weak and shallow echo to WNW, so let techs stop it after rain map for another solar scan.

1556	techs started ClimoShallow after finishing solar scan work. * There was a problem starting it at 1551 -(ignore sweeps 1551-1556)

1600	Stopped scan sequence and restarted ClimoShallow to sync up.  However no echoes are present in range...

1730	Mostly clear still...though some weak echoes are forming past 150km range to NE of radar.

1800	Nesbitt here -- Running ClimoShallow

1906	A few cells to NE at 150+km rainge moving NW.  Still no echo at 5.5deg elevation, so will stay in ClimoShallow.  Very supressed behind yesterday's wave passage.

1913	Sounding shows little shear + dry layer between 850-650mb. Only 350J of CAPE with 184J CIN. Tomorrow looks more promising as WV image shows a tropical wave approaching from SE.

1952	Barely topping one cell at 5.5deg at 120km range, 045 azimuth. Will examine next 5.5deg scan to see if still topped.

2009	Storms continue to pulse up and down in terrain above 7000ft.

2046	Lone cell popped up over Gulf, one cell on SBF NW at 100km range.  Another cell to SE along

2145	ClimoFar mode - cell along sea breeze finally broke cap to NW

2249	Another cell popped along 330 radial to replace previous cell -> other convection still limited to mountains.

2308	Noted second trip to SE - a large MCS is located along coast well south of Mazatlan.  May link up with convection in east part of domain -> stay tuned!
