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?"

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.
