*Premium* Storm Update – Wed 09/30/26 7:30AM | A Near‑Miss Yet Again as Soaking Storm System Only Grazes the Denver Area Today

A slow‑moving, high‑stakes storm has been creeping toward Colorado all week — a rare mash‑up of an autumn upper‑low and the juicy tropical remnants of Hurricane Polo — and for a moment, it looked like Boulder and Denver might finally score a true soaking. But as the atmosphere loves to do, the script flipped late. Today’s update breaks down how this once‑promising setup unraveled over the last couple days, why southern Colorado is now squarely in the bullseye, and what scraps of moisture the Front Range can still squeeze out as the system passes by to our south.

    Maybe on a slower weather day you can include a short layman’s explainer of the European vs US forecasting dynamic. And meaning of “ensemble” in meteorology.

    Greatly appreciate the newsletter!

      Thanks for the idea. Sometimes we do add those nuggets of info in separate posts or just tacked onto the end of the daily updates. Will consider increasing the frequency of those. Cheers.
