Finally have data that reflects a decent rain event. The humidity intersects the temperature for the first time and the pressure is slightly elevated. This is one of the first medium rain events captured on this system. Pretty interesting.

Had much cooler weather yesterday with humidity and pressure up-trend. This coincided with lightning storms in the evening… some passed right over the house.

Here’s a 2 week view that captures the storms over the last few days as well as the intense heat wave from the start of the 2 week period. The swing between high and low temperature has flattened out due to the average humidity still being in the 20-30% range, even when the temperature is peaking up over 100.
Very interesting to note the difference in the humidity peaks (less pointed, a few dips at the top) when the storms are in place. Not sure if this is sampling the latent presence of clouds?

On the 23rd we see the humidity going away quickly and the temperature rising. Combined with falling barometer, we expect little chance of lightning!

Here are results of last night’s storm. A little bit of lightning at the house, but nothing like the power of the one a few weeks ago.

Updates. Lots of rain and lightning around Tucson yesterday, but only a small bit picked up at this location.
Had another round lf lightning in Tucson, but most of it was more than 20km away. Humidity is dropping a bit, and so temperature moving back up.

Lightning strike energy and distance for the last week plotted with humidity. Lightning strike energy is unitless, relative energy. Distance is in miles.
