Weather Nws

US weather forecasts via National Weather Service (NWS) with automatic fallback to global weather for non-US locations. Provides detailed accumulation data, watches/warnings, and actionable timing.

Automatically falls back to global weather via wttr.in for international locations.

File contents

Weather NWS Skill

Get detailed US weather forecasts from the National Weather Service with automatic global fallback.

When to Use

✅ USE this skill when:

"What's the weather in [US city]?"
"How much snow is expected?"
"Winter storm forecast for [location]"
"Will it rain tomorrow in [US city]?"
Any US-based weather query

🔄 Automatic fallback:

Non-US locations → wttr.in
NWS API unavailable → wttr.in
Both sources fail → clear error message

Quick Start

# Run the unified weather script
python3 ./scripts/get_weather.py "New York, NY"

# Force specific source if needed (normally auto-detected)
python3 ./scripts/get_weather.py "London, UK" --source wttr

Output Format

The script provides consistent output regardless of source:

Header: Location and current alert status Today → Tonight → Tomorrow: Structured timeline Accumulation: Specific snow/rain amounts when available Bottom Line: Actionable summary with timing

Implementation

The script handles:

Geocoding location to lat/long
Detecting if location is in US
Calling NWS API for US locations (detailed accumulation)
Falling back to wttr.in for non-US (basic forecast)
Formatting consistent output with emojis and structure

Limitations

NWS: US only, requires internet, rate limited
wttr.in: Global, less detail on accumulation, no official watches/warnings

Examples

US winter storm query:

python3 ./scripts/get_weather.py "Boston, MA"

→ Returns NWS data with accumulation estimates

International location:

python3 ./scripts/get_weather.py "Toronto, Canada"

→ Automatically uses wttr.in, notes it's non-US
