But, it looks like we will get beautiful weather for the 4th of July weekend.
Alex will meander across Northern Mexico and slowly devolve. As it does, it will break up the monsoon pattern and draw moisture back to the south. Another sign of the break up of the pattern will be a return of dry southwest winds to the area.
This isn’t unusual. Hurricanes effect the weather for at least 1000 miles. Rita and Katrina dried out Northern Arizona as they went ashore near New Orleans in 2005. I think the moisture will linger to the south and make a quick return next week.
