SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quickly answers weather, severe weather, radar/model imagery, and verified thermodynamic calculations without users manually stitching multiple APIs and tools together.

Core Features & Use Cases

  • US Observations & Forecasts: Pulls current conditions, NWS forecasts, METARs, alerts, and quick briefings for a requested location.
  • Global Weather: Retrieves world-wide current weather via Open-Meteo for non-US locations.
  • Radar + Model Imagery: Generates radar images and model field PNG maps (including storm overlays) with optional region zoom.
  • Verified Calculations: Computes meteorological values (e.g., dewpoint, LCL, CAPE/CIN, shear, helicity) using metrust-backed functions.
  • Soundings + ECAPE: Downloads verified model pressure-level profiles, produces derived sounding parameters, and runs parity-verified ECAPE/NCAPE.

Quick Start

Ask for current conditions and a short forecast by requesting: "What is the weather in Norman, OK right now and what should I expect over the next several periods?"

Frequently Asked Questions about weather-plugin

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get current weather conditions and NWS forecasts for a specific location?

To get current weather conditions and NWS forecasts, you can ask for a quick briefing by location. The tool retrieves current conditions, forecasts, alerts, and METARs for US locations, and global observations via Open-Meteo for non-US areas.

Can I generate radar imagery and model maps with storm overlays?

Yes, you can generate radar imagery and model field PNG maps with optional region zoom and storm overlays. The tool renders radar and model maps directly, using Rust-backed bootstrapping for rendering if required binaries are not preinstalled.

How do I calculate CAPE, CIN, or helicity from model soundings?

You can calculate CAPE, CIN, helicity, LCL, and dewpoint using verified meteorological functions. The tool downloads model pressure-level profiles, produces derived sounding parameters, and runs parity-verified ECAPE and NCAPE calculations.

Do I need a specific environment to run meteorology calculations and radar rendering?

Yes, you need a Hermes environment with registered tool schemas to run meteorology calculations and radar rendering. The tool supports Rust-backed first-use bootstrapping to automatically execute radar rendering and ECAPE when binaries are not preinstalled.

Does this tool support decoding aviation METARs and retrieving SPC severe outlooks?

Yes, the tool supports decoding aviation METARs and retrieving SPC severe weather outlooks. It covers NWS-based conditions, alerts, and forecasts alongside specialized severe weather and aviation data retrieval for requested locations.

What is the best way to retrieve global weather observations outside the US?

The best way to retrieve global weather observations outside the US is using the Open-Meteo integration. It fetches worldwide current weather data, complementing the NWS-based observations and forecasts available for US locations.
