Right now, doesn’t look like the monsoon moisture is getting close to the US border yet… it takes a couple of weeks to move north out of Mexico.
Most years, the monsoon pattern gets here during the first week or two of July.
It was early the last 2 years.
Why is it late? Usually when we have a wet winter, things don’t set up right… and the upcoming El Nino is also changing things up a bit.
