July 2012 — Hot and Dry

Wednesday, August 1st, 2012

I recorded 20 days during the month with a high temperature of 90° or higher(!). Max temperature for the month was 102°. In addition to the heat, the month was mostly very dry although we were lucky on a couple of occasions thanks to isolated thunderstorms. A gust to 51 mph was recorded during a thunderstorm on July 18. The total rain was 2.35 inches but only 2 days during the month had 0.50 inch of rain or more. So there were considerably more dry days then rainy ones. In addition, using the new CoCoRaHS Evapotranspiration gauge I recorded a monthly total ET of 6.38 inches meaning our net water balance was -4.03 inches.
