October Dryness Makes Headlines

This morning's headline in the Tucson Star newspaper highlighted the October dryness, and also warmth. However the story also shows how variable precipitation can be across metro Tucson. While the airport has only had  four years since 1948 with no rainfall, Here on the dry north side of the City, I have measured no October rainfall four times since 1999  (1999, 2005, 2010, and 2013). Quite a difference, perhaps the NWS stats included months with a Trace as having rainfall? Wettest October here at house was in 2000, with 5.06 inches - quite a range.

As for the rest of the month the forecasts are not good - above graphic shows QPF plumes for the airport through Monday evening (from SPC SREF - Short Range Ensemble Forecast system). There may be a weak system moving across Arizona on Halloween, which might bring a very slight chance of a treat.

Photos below are from the campus web cam hourly views of the Catalinas for the past week - I don't see a single bit of cloudiness.

As for the warm temperatures - our HVAC people are about to show up for the annual check of our heating systems, but the air conditioning continues to be running each afternoon - still!
