Yesterday's high over 109 °F

Yesterday the Stonehill News weather station recorded a high of 108.1 °F but we lost power and Internet during the hottest part of the day. The mercury thermometer topped out between 109 °F and 110 °F (approximately 109.5 °F, but I don't want to state it too precisely as the mercury thermometer has lower resolution than the digital one).

ID	Location	High
KCAALTAD1	Top Of Lake Ave	108.3 °F
KCAALTAD2	Stonehill Dr	108.1 °F
KCAALTAD3	N. Mount Curve	104.1 °F
KCAALTAD7	Zane Grey	104.4 °F

The other three Altadena weather stations all seemed to have stayed online through the day yesterday. Above are yesterday's local highs as recorded on WUG.

Last year, July 22 is the day (not) to beat with a high of 112.5 °F recorded at Stonehill News.

It seems that we may have the dubious distinction of being the hottest place in Altadena =)

I considered the possibility that my temperature gauge was out of calibration, but it generally agrees with the mercury one. I guess it's possible they're both reading high, but not likely. They are both positioned in the shade on the north side of the garage, and never see direct sun. Assuming that the thermometers are reading correctly, I assume that there is some micro climate effect having to do with the orientation of the Gooseberry Canyon (watershed)
