Daily high / low by model

Tap a day, or drag across a chart, to see that range hour by hour for each model. Precip is liquid-equivalent; snow is depth at Open-Meteo's fixed 7:1 ratio. Spread is the range of highs; amber means the models disagree by 8°F or more.

Temperature

Accumulated precipitation

Running total from the start of the window. Diverging lines = models disagree on timing or amount.

Accumulated snowfall

New snow, depth from water equivalent at 7:1. Real ratios run roughly 6:1 to 20:1+ depending on temperature.

Freezing level

Height of the 0 °C level. Below the dashed site-elevation line, precipitation at the site is likely snow; snow often reaches 1,000 ft or so below this level.

Wind gusts

WeatherNext 2 comes from the Ensemble API: its line is the mean of 64 members, the shaded band spans the 10th–90th percentile, its daily high/low is the median of member highs/lows, and it has no gust output. AI models (AIFS, AIGFS, WeatherNext) and some globals output 3- or 6-hourly steps that Open-Meteo interpolates to hourly, so their daily highs and lows are smoothed and tend to under-shoot extremes. Models drop out past their forecast horizon or outside their coverage (NBM is US-only).
