Weather Whisperer v5 — Park Operations Weather Intelligence

Serverless GCP pipeline that ingests METAR, GOES-18 satellite lightning, upper-air soundings, and NWS forecasts/alerts into BigQuery; runs 6 purpose-trained ML models plus Gemini for 2-hour venue-specific nowcasts; and publishes a curated JSON API on an adaptive 1–15 minute cadence. Includes a working cross-cloud agentic extension (AWS Bedrock → Azure Function → BigQuery).

Click any component to explore it in the full case study.

Input A
METAR Surface Observations
aviationweather.gov API — 17 Florida stations every 10 minutes: temperature, humidity, precip, wind, pressure, visibility, wx codes (TS/FG/BR)
17 stations · 10-min cadence
Input B
GOES-18 GLM Lightning
Satellite lightning flashes within 20 mi of parks feed spatial storm-boost logic in the ML nowcasts. Dedicated proximity/closure-zone product detailed on the Lightning Tracker page.
GOES-18 · 10-min ingest
Input C
Upper-Air Radiosonde Data
University of Wyoming soundings (Station 72210 Tampa Bay) — CAPE, CIN, Lifted Index, K-Index, Total Totals, Showalter, PWAT for ML scoring.
UWY Soundings · every 12 hrs
Input D
NWS Forecast & Alerts
api.weather.gov 48-hr forecasts plus active alerts — feeds the 5-state storm severity engine and forecast-enhanced risk view.

Cross-Cloud Agentic Pattern
AWS Bedrock (Claude) agent calls weather "tools" implemented as Azure Function endpoints, which query these BigQuery views via a read-only, Key-Vault-secured service account — a hand-rolled precursor to MCP/A2A tool-calling standards.
