Brief Summary of July and Misc.




July 2010 Summary - Here at house rainfall totalled 3.26" - making it the 5th wettest July of the 12 years I've kept records. Rain of 0.10" or more fell on only 4 days and the bulk of the monthly total occurred on two days - the 29th and 30th. Thus what was mostly a very hot and dry month ended up wet. Shrubs and plants are quite happy with the soil moisture and higher humidity. Shown in top image is a Texas variety of purple sage. Mexican rain lilies are also bursting into bloom after the rains.
--------------------------------------------------
At TUS rainfall was 2.71" (the 36th wettest July since records were kept here); again with the bulk of the rain falling on just two days. PHX at Sky Harbor ended up with 1.97" (the 13th wettest July on record there); with virtually all of the rain falling on the last two days of the month. Out in Yuma, July brought a only a trace of rain; tied with other Julys having no measurable rainfall. So this month, particularly at low elevations, illustrates well the vagaries of daily weather within the highly variable desert climate regime.

After the wet ending of July, southeast Arizona was very suppressed on Sunday the 1st, with a slight uptick late yesterday on the 2nd. See bottom two regional radar charts from NCAR RAP.
