Here’s a view of the last month of weather. Last week we could see the drying up trend start. It’s possible that this is the start of the end for monsoons.
Tucson Monsoon Weather – 9/4/2018
Lots of weather over the last couple of days! You can see the buildup of the cloud cover, as sampled by the light spectrum measurements starting on 8/31. Humidity gradually increased over that period and pressure dipped slightly. The intersection of the humidity line and the temperature line on 9/2 is a typical indicator of rain. In this case, the rain lasted for around five hours or so. Lots of lightning captured and some of it quite close! All cleared up on 9/3 and we see the humidity drop quickly during the day.
Tucson Monsoon Weather for Sept 01, 2018 – small rainstorms
The system that passed through on September 1 was small but widespread. It brought some rain and lightning. You can see some of it captured here. Humidity stayed low despite the rain, unlike the events from August 23-25. Lightning strikes had smaller intensities too.
Tucson Monsoon Weather 8/6/18
Storms have abated and the humidity has fallen significantly. Slight downtrend on pressure and uptick in temperature. No hope for clouds and storms today, it appears.
