Tucson Monsoon Weather – Is the Monsoon Returning? – 9/18/2018

In the first chart below you can see the last full month of data.  There was quite a spike in humidity and lightning earlier in the month, but unfortunately it dried up.  The daily humidity oscillation amplitude have decreased and the temperatures have increased slightly since that round of storms.

However… looking at the second chart, which focuses on the last week of data, we can see the humidity numbers increasing.  The sensor has been detecting small lightning events (they may/may not be real, but we have had cloud cover at times).  Are we going to have a return of the monsoon?
