A strong El Niño is forecast to shape winter 2026–27, and the pattern points at a familiar list of states. When El Niño shifts the storm track south, the Southwest and southern Rockies tend to see an active, wetter winter — and forecasters now favor above-normal snowfall across California, Utah, Arizona, New Mexico, and parts of Colorado, while Washington, northern Montana, and the Upper Midwest lean below normal.
This ranking translates the forecast into fleet terms: which states are most likely to see heavy snow, why, and what fleets there should stock before the first storm.
How this list was compiled. States are ranked by the strength of the above-normal snowfall signal in publicly available 2026–27 outlooks (NOAA CPC ENSO probabilities and OpenSnow’s winter forecast) as of late August 2026. Seasonal outlooks are probabilities, not guarantees; always check the latest CPC discussion before committing resources.
The 2026–27 Ranking: 5 States Most Likely to See Heavy Snow
1. California (Sierra Nevada)
Forecast lean: Above-normal snowfall favored across the Sierra Nevada.
Why it leads: Strong El Niños frequently deliver prolific snow to the Sierra, and the 2026–27 outlook favors that pattern. Mountain passes and highway routes face long seasons with heavy, wet snow events.
Fleet action: Stock carbide edges for abrasive pass routes, keep spare edges per plow, and expect changeout-heavy months. OpenSnow 2026–27 forecast
2. Utah (Wasatch Range)
Forecast lean: Above-normal snowfall favored across Utah.
Why it ranks here: The Wasatch Range is a classic El Niño beneficiary, with a strong above-normal signal in the 2026–27 outlook. Canyon routes and ski-area access roads mean frequent plowing on abrasive surfaces.
Fleet action: Verify skid shoes and wear bars early; carbide edges earn their cost on canyon and pass routes.
3. Colorado (Southern and Eastern Portions)
Forecast lean: Above-normal in the south and east, with a mixed signal in the north.
Why it ranks here: Southern and eastern Colorado sit in the El Niño storm track, and forecasters favor above-normal snowfall there while northern areas stay more uncertain. Interstate and mountain maintenance crews should plan for an active season.
Fleet action: Order before October; keep a changeout cadence for high-mileage interstate routes.
4. New Mexico
Forecast lean: Above-normal snowfall favored, strongest early and late in the season.
Why it ranks here: New Mexico is frequently highlighted as a strong El Niño snow winner, with the strongest chances for above-average snowfall early and late in the season. Events can be sharp and infrequent, which punishes unprepared fleets.
Fleet action: Even a short season needs ready edges; keep spare hardware kits for back-to-back events.
5. Arizona (High Country)
Forecast lean: Above-normal snowfall favored in higher elevations.
Why it ranks here: Arizona’s high country and mountain corridors are part of the favored Southwest zone, with snow events concentrated at elevation. Fleets that only occasionally plow need edges that do not degrade in storage.
Fleet action: Inspect edges before the first event; rubber-flex options suit mixed pavement and shoulder conditions.
Regions Leaning Below Normal (Notable)
Pacific Northwest and Upper Midwest: Forecasts lean below normal across Washington, northern Montana, and parts of the Upper Midwest. Lighter seasons still include sharp cold snaps and major single events — keep edges ready at lower changeout frequency.
Snowiest States at a Glance
| Rank | State | 2026–27 Lean | Fleet Priority |
|---|---|---|---|
| 1 | California | Above normal (Sierra) | Carbide edges, high changeout stock |
| 2 | Utah | Above normal (Wasatch) | Skid shoes, pass-route edges |
| 3 | Colorado | Above normal (south/east) | Pre-October ordering |
| 4 | New Mexico | Above normal (early/late season) | Back-to-back event kits |
| 5 | Arizona | Above normal (high country) | Storage-safe edges |
What a Heavy-Snow Year Means for Cutting Edges
More snow does not automatically mean faster edge wear — the type of snow and the surface underneath decide that. Heavy wet snow and ice events put more impact and abrasion on edges; more events mean more changeouts; and freeze–thaw cycles stress tip bonding. For the states above, plan for all three: stock spare edges, verify braze quality, and schedule changeouts by miles and events rather than by visible wear.

Frequently Asked Questions
Which states get the most snow in an El Niño winter?
El Niño typically shifts the storm track south, favoring above-normal snowfall across the Southwest and southern Rockies — California, Utah, Arizona, New Mexico, and southern Colorado are the usual leaders, and the 2026–27 outlook agrees.
Is this ranking a guarantee?
No. Seasonal outlooks are probabilities. Check the latest NOAA CPC discussion before committing fleet resources, and update plans as the outlook is revised.
What should fleets in heavy-snow states stock?
One spare cutting edge per plow, matched hardware kits, and carbide-tipped edges for abrasive and ice-contact routes. Order before October when lead times are shortest.
Do below-normal states need prep?
Yes. Below-normal leans still include sharp cold snaps and major single events. Keep edges and hardware ready at lower changeout frequency.
Ready Your Fleet for the Forecast
Whatever your state’s signal, edges decide your cost per storm. Compare carbide snow plow blades and replaceable carbide inserts, then contact the SENTHAI team with your state and fleet size for a pre-season recommendation.
