What's driving this forecast

ENSO: El Niño favored (99%)

The 2026-27 season is simulated by resampling Copper Mountain's historical seasons weighted toward El Niño analog years. NOAA CPC El Niño Advisory (June 11, 2026): El Niño conditions are present and expected to strengthen into winter 2026-27, with a 63% chance of a very strong event (Niño3.4 ≥ +2.0°C) during Nov-Jan. CPC DJF strength odds: very strong 46%, strong 33%, moderate 16%. IRI (June 22) concurs at 98% El Niño for DJF. Latest observed ONI (AMJ 2026): +1.0.

Regional ENSO signal: favorable (weak-moderate)

A north-south dipole: El Niño favors the southern ranges (+10-25%) via the southern storm track, is roughly neutral in the north. Statewide signal is modest. Applied as a +2% tilt at partial weight.

Pre-season: climate drivers only

Day-to-day weather models have no skill this far out, so the near-term forecast contributes 0% weight today. The simulation leans entirely on ENSO-conditioned climatology — exactly what an honest seasonal outlook should do in summer. Weighting shifts toward live forecasts as opening day approaches.

The regional readColorado · from the 2026-27 outlook

El Niño splits Colorado along a northwest-southeast axis: the energized subtropical jet favors the San Juans and Sangre de Cristos, while Steamboat and the northern mountains lose their La Niña edge. Strong-event analogs (1982-83, 1997-98, 2023-24) skew average-to-above statewide with storm-heavy springs, though 2015-16 was mixed. Play it as southern Colorado above average, the I-70 corridor near normal, and March-April loaded.
