Yes, I am using a handful of different APIs. My full terminal weather setup deserves its own blog post... but until then, here are some zsh snippets, scripts, and curls to get you started.

Rough weather information for next days and hours:

    # Find zone with curl https://api.weather.gov/points/40.5878,-103.0694
    ZONE=${ZONE:-CAZ508}
    echo "Forecast for zone $ZONE"
    curl -s -A MyWeather/1.0 https://api.weather.gov/zones/forecast/$ZONE/forecast \
        | jq -r '.properties.periods[] | [.name, .detailedForecast] | join("\t")' \
        | column -t -s $'\t'

    # Find grid with same curl
    GRID=${GRID:-MTR/93,131}
    echo ""
    echo "Next 24 hours for grid $GRID"
    curl -s -A MyWeather/1.0 https://api.weather.gov/gridpoints/$GRID/forecast/hourly \
        | jq --arg date $(date -Is) -r '.properties.periods[] | select(.startTime >= $date) | [(.startTime), ((.temperature|tostring) + " " + .temperatureUnit), (.windSpeed + " @ " + .windDirection), .shortForecast] | join("\t")' \
        | column -t -s $'\t' \
        | head -n 24

Some docs on the "DWML rest API" that provides the dewpoint/humidity forecasts that I mentioned earlier:

https://graphical.weather.gov/xml/docs/elementInputNames.php

Here's the script I use to access that API but it is still under active development and is pretty tailored for my situation. Please forgive jankiness. Give it LAT / LNG environment variables.

Bonus points, for CA fire season, here's a script that shows PM2.5 for AirNow stations near a certain LAT/LNG:
