Dewpoints have remained fairly high all month. We broached 50F for the dewpoint on Saturday. The average dewpoint (from Tucson NWS Tracking site) for the day was in the low 40’s. The moisture is trying to stream up from the Gulf of Mexico and is saturating Northern Mexico. It hasn’t quite made it to Arizona in full force, yet. One of the components of the monsoon is the formation of a thermal low pressure system. We are probably missing some heat to cause the lifting of the are to form the low pressure system.
Dones’t it have to get hot before the monsoon starts?
