Rain Wrap-up 2014

posted by Jeremiah 7/01/2014 07:02:00 PM

The Stonehill News weather station recorded 6.66 inches of precipitation for the rain season ending June 30, 2014. I have made a tradition of reporting what my neighbors Dan Gollnick and Bill Westphal recorded, going back to 1999 and 2003 respectively.

Here are the available seasonal totals:

Season    PacRad     KCAALTAD1   SHN
1999-2000  19.76"      --        --
2000-2001  21.22"      --        --
2001-2002   8.27"      --        --
2002-2003  24.47"      --        --
2003-2004  15.47"     14.72"     --
--------------------------------------
2004-2005  62.56"     56.66"    61.61"
2005-2006  24.06"     22.37"    23.35"
2006-2007   6.81"     6.52 "     6.15"
2007-2008  26.04"     24.66"    23.64"
2008-2009  16.34"     15.77"    15.09"
2009-2010  26.50"     25.55"    24.92"
2010-2011  34.49"     34.17"    30.70"
2011-2012  13.62"     13.66"    13.39"
2012-2013  11.58"     11.59"    11.39"
2013-2014   6.38"      6.82"     6.66"
--------------------------------------
(04+) Avg  22.84"     21.78"    21.69"


I've included averages from the 04-05 season to the present

I included lines on the map from both of the Stonehill stations to Bill's station. According to Google Maps, Bill is at 1640' and is approximately 1.25 miles WNW of here.

That puts him at the exact same elevation as PacRad, but he's on slightly flatter terrain (no canyon walls directly adjacent to him). I speculate that the shape of the terrain more than the elevation is causing microclimatic differences, but it does not seem to follow a predictable pattern.

We assume the variation is due to micro climatic differences, not calibration or placement problems. The fact that the percent difference is not consistent year over year supports this assumption.

Rain Wrap-up 2012

The rain season of July 1, 2011 to June 30, 2012 ended with 13.39 inches recorded on the Stonehill News weather station. I also have made a tradition of reporting what my neighbors, Dan Gollnick, at the top of Stonehill has recorded, going back to 1999, and Bill Westphal (Wunderground call sign, KCAALTAD1) over near Loma Alta Elementary School since 2003.

Here are the available seasonal totals:

That puts him at the exact same elevation as PacRad, but he's on slightly flatter terrain (no canyon walls directly adjacent to him). I speculate that the shape of the terrain more than the elevation is causing Dan to average almost 2" more than Bill and me about 3/4" more than Bill.

PacRad consistently logs a bit more rainfall, collecting 750 feet due North and 100 feet higher elevation. We assume this is due to micro climatic differences, not calibration or placement problems. The fact that the percent difference is not consistent year over year supports this assumption.

Unpoppable at the Folly Bowl

Yes, this is a free jazz quartet, jamming on rubber-band-sax, balloon-bass, guitar and drums. We saw them at the Folly Bowl in Altadena on Sept 10, 2011.

A Fine and Pleasant Misery: The Backyard Safari

posted by Jeremiah 9/15/2011 11:54:00 AM

The chapter titled The Backyard Safari from A Fine and Pleasant Misery by Patrick F. McManus was forwarded to me yesterday. I was reading it by myself in the SJC airport and couldn't contain my laughter. (It's only six pages long) Enjoy:

Snow in Altadena Feb 26, 2011

posted by Jeremiah 2/27/2011 02:17:00 PM




As the week progressed, and Saturday drew near, weather predictions of snow down to 500 feet persisted, leading many to hope it may actually come to pass. After a rainy night, morning broke Saturday, and it seemed like we might have missed our chance when some light brief hail and more rain started falling.

Then a strange thing happened late in the morning; the temperature dropped suddenly by about 10 degrees F, and an unusual kind of "soft hail" mixed with rain began falling. It was the source of much excitement. The entire neighborhood seemed to be out on their decks, judging from the periodic shrieks of excitement from various directions.

By my rough estimation, I think it started at around 11:45am. I've marked that approximate time with a yellow line on the various charts from the weather station. There are some very interesting and unusual patterns that came in with this system.
