We have been away since Friday afternoon. When we left town there had been no further rain during the day on Friday. We drove south down Highway 83 after dark Friday night and winds were quite variable. Near the USGS Barrel Canyon stream gauge winds were nearly calm around 7:30 pm. However, at the high spot a bit farther south (i.e., just east of the proposed Rosemont Cooper mine) winds were very strong from the west, blowing at an estimated 30 to 40 mph. When we returned home late yesterday (Saturday November 10th) there was an additional 0.05" in the rain gauge - making the storm total only 0.16". The low on Saturday morning here at house was 38F, but this morning it has dropped to 28F - making this the first below freezing morning here this Fall.
Above and below are two shots taken from Santa Rita Abbey at about 8 am MST Saturday morning. Heavy storm clouds were hanging on the Santa Rita mountains (view is to the west where clouds obscure the mountains). Still some Fall colors out there. There was also a bit of a morning rainbow present in the top photo.
Looks like tonight will be a bit of a challenge for forecasting low temperatures. Above is Atmo's early WRF-GFS forecast of surface conditions across the metro area at 6 am MST Monday morning. Dewpoint temperatures are very low and rapid cooling should occur after sunset. But the model forecasts some east winds after midnight. The temperature ranges from 52F in the northeast part of town, to 47F at the airport, to 35F at Green Valley. Here at the house I expect that conditions will remain calm during the early morning hours and that our low will be in the middle 20s, but other locations will be more difficult to call.
Today we remember all who have served their country in the military - Veterans Day - celebrated as a Holiday tomorrow.
