Last week’s storm finally delivered the kind of soaking rain we’ve been waiting months to see, but don’t get used to it. The atmosphere is shifting back into a familiar pattern this week, with summer-like warmth, abundant sunshine, and another surge of tropical moisture headed toward the Southwest. The catch? Most of that moisture will never make it to the Front Range. In this week’s update, we look at the drought-improving impacts of last week’s storm, why the San Juans are poised to cash in yet again, and whether a late-week cold front can squeeze out a little bit of rain for us before temperatures finally start feeling a bit more like October.

12th Annual BoulderCAST First Snowfall Contest

Ready or not, snow season is lurking out there somewhere. Maybe you’ve already dusted off the skis, mounted the winter tires, or convinced yourself that buying an Epic Pass counts as meteorological preparedness. Now comes the big question: when will we see our first measurable snowfall of the season? If recent years have taught us anything, it’s that Mother Nature doesn’t always follow the script. We’ve experienced both the earliest and latest first snows on record within the last six years, proving that just about anything is on the table.

That’s why it’s time once again for the BoulderCAST First Snowfall Contest. Take a look at Boulder’s snowfall history within, then submit your prediction for the date of Boulder’s first measurable snow (0.1″ or greater) and how much will fall. The closest forecasts will earn prizes, bragging rights, and the satisfaction of being more accurate than your friends.

After months of drought, the Front Range is finally cashing in on a meaningful storm, with Boulder already topping an inch of rain and more moisture still to come. But are the best rains already behind us? A closer look at the storm’s evolving track suggests the answer may be yes, while a hard freeze waits on the other side of this long-overdue autumn gloom.
