Hosts Zack Guido and Mike Crimmins are kicking off 2026 with a look at this winter’s weird weather in this month’s Southwest Climate Podcast.  They do a recap of the last couple of months of precip and temps.  They do a review of large scale climate patterns - Madden–Julian Oscillation, Greenland Block - and get into a deep discussion about the Polar Vortex.  They cover the not-so-great coverage of snowpack and look at the forecasts through peak season going forward.  Rounding out the episode is the NOAA announcement on RONI (a topic of past episodes) and a preview of the AI focused episode that is in the works.
