TUCSON (KVOA) - 1.62 inches of rain was recorded at the Tucson Airport making 2020 not only the hottest year on record for Tucson, but also the second driest.

The monsoon is the time of year where we see the vast majority of rainfall we can expect in a year. Usually we see about 6 inches of rain. This year we weren't even close. 

Meteorologist Shea Sorenson has been tracking the rain all summer and said this year is the worst she can remember growing up in Arizona.

Shea said, "It's a huge bulk of our rainfall for the whole year and when it's a really slow Monsoon like the one we've seen I'm sad. I hate going up in front of the 7-day forecast and saying no rain."

Chief Meteorologist Matt Brode says this year we never saw the early signs of monsoon and that prevented the momentum necessary for storms to build. 

Matt said, "In the old days we used to define the monsoon as three consecutive days with dew points of 54 and higher. That would build into dry thunderstorms. Then the dry thunderstorms would build into scattered thunderstorms around Santa Cruz and Cochise county. Then those thunderstorms would move into Tucson and become wet thunderstorms. We just did not have momentum building up. We did not have any consistency we did not have any easterly waves moving through."

2019 was also a slow Monsoon, but we also saw plenty of rain in late November and December to make up for it. It looks like we will be hoping for late year rain once again.
