A focused Sunday-through-Tuesday storm brings the only meaningful snowfall window, with the best accumulation in Canterbury and lighter spillover elsewhere. Guidance supports a regional high-elevation refresh around 20 cm-30 cm at the top end, while most other fields stay in a modest 1 cm-6 cm range. Expect mostly dense to moderate snow quality during the core burst, then a shift to quieter weather for the rest of the period with only low-confidence flurries later next week. Most fields are currently listed closed, so this cycle is mainly a snowpack-building event rather than an immediate lift-access cycle.
For Sunday afternoon through Tuesday, the individual guidance is converging on timing, with snow expanding Sunday, peaking Sunday night, and tapering through Monday night into early Tuesday. Intensity agreement is strongest in Canterbury, where Mt Hutt, Porters, and Mount Dobson consistently carry the core of the storm, while North Island volcanoes and Queenstown-area fields remain lighter. Intensity spread is moderate, with heavier solutions roughly one tier above the lighter set, so confidence is high on where snow falls but only moderate on exact storm depth outside the top three resorts. Snow-level guidance while precipitation is active clusters mostly around 900 to 1,700 meters, with brief pushes near 1,900 meters in warmer pulses, so upper-mountain coverage improves the most. Temperatures during snowfall generally run from -5 C to 1 C at elevation. Wind guidance also converges on a Sunday night to Monday peak, with exposed sustained speeds near 30 to 60 km/h and frequent gusts from 70 to 110 km/h, locally higher near the central North Island volcanoes.
Snow quality in the main wave trends dense to moderate rather than fluffy, with storm SLRs mostly 7-12 and occasional dips to 5-7 during warmer periods. That setup favors heavier snow at lower elevations and somewhat better quality aloft during colder overnight hours. After Tuesday, guidance converges on a mostly dry stretch with lighter winds and no organized storm signal through at least Friday. Beyond that point, the solutions diverge more sharply on timing, intensity, snow levels, and wind impacts, with one camp trying to form a weak weekend pulse while others keep New Zealand largely dry. Confidence is low in that extended signal, so the conservative expectation is limited change for most areas, with only a small chance of a light top-up around 2 cm-10 cm in favored higher terrain if the wetter scenario develops.
