It looks like a significant pattern change is coming this week with a stalling boundary that will extend back into Texas. Rounds of rain will move across the Mountains later this week and possibly into the weekend. I'm seeing a pesky trough building in and lowering pressure across the Gulf as a monsoonal trough begins to organize in the Western Caribbean. Our sensible weather suggests that we begin to see an El Nino pattern slowly become established and rain chances increase all across the SE Region. Keep an eye on an early tropical system slowly organizing somewhere in the Gulf at the end of May or early June.
