It’s now in the record books: for the first time ever, all 30 days in June were greater than 100 degrees in Tucson.
So if you thought it was unusually hot, you were correct.
Chapter II: The monsoon
Thanks to the position of high pressure, which also brought us the heat, moisture has already begun moving into the region.
Dew point’s at TIA are now near 50 degrees and forecasted to increase over the next few days.
You may recall that the dew point is the absolute measurement of how much moisture is in the lower levels of the atmosphere.
The following images are high-resolution depictions of projected rainfall across the region for the next 72 hours.

This image is our 72 hour RPM model indicating a noticeable uptick in our monsoon.
We like to look at other model runs to make sure that there is consistency among our forecasting tools.

Bottom line: The first week of July looks to be at least the beginning of what I hope is a great monsoon.
*Matt, * * * *I want to say a couple of things. First, I HOPE KVOA will make you their permanent meteorologist.
Secondly, I very much enjoy how you report the weather. Far too many ‘glamorize’ the weather and do the same with the way they report it as IF they are on stage or are a star.* * * *Your reporting is very straight forward, very clear, very comprehensive, but NOT glamorized. I appreciate that and I want you to know you are the ONLY weather person I watch for my weather.* * * *Thank you for your impressive style of weather reporting. I wish you much success at KVOA and with your return to Tucson. * * * *Jay Johnson*
Thanks Jay! Those are very kind words.
