About NashvilleWeather.Org

NashvilleWeather.Org is a free, community-focused live weather dashboard built for the people of Nashville and Middle Tennessee. It delivers real-time weather data, interactive radar, detailed forecasts, severe weather alerts, power outage tracking, and local emergency news — all in one place, with no app downloads, no subscriptions, and no paywalls.

What NashvilleWeather.Org Does

The dashboard provides a comprehensive, at-a-glance view of current and upcoming weather conditions for the Nashville metro area and surrounding Middle Tennessee counties. It combines data from multiple trusted sources into a single, fast-loading interface designed to be useful whether you're checking the morning forecast or tracking a severe storm.

Interactive Radar

Powered by RainViewer and displayed on an interactive Leaflet.js map, the radar offers three modes: past radar (animated loop of the last two hours), live (current conditions), and nowcast (short-term precipitation forecast up to two hours ahead). Full playback controls let you step through frames, adjust opacity, and zoom to any area in the region.

48-Hour Hourly Forecast

A detailed hour-by-hour forecast table showing temperature, weather conditions, precipitation probability, and wind speed for the next two full days. Data comes from Open-Meteo, a free, open-source weather API.

14-Day Daily Forecast

A 14-day outlook showing daily high and low temperatures with visual temperature range bars, weather conditions, and precipitation probability. Each day's forecast is presented as a compact card with color-coded temperature gradients that make it easy to spot trends at a glance.

Severe Weather Alerts

Real-time severe weather alerts from the National Weather Service Nashville office (OHX). Alerts are fetched from the NWS API, filtered to the NWS Nashville forecast area, and color-coded by severity — from minor advisories to extreme warnings. The most urgent alert appears as a sticky banner at the top of the page. Alerts auto-refresh every five minutes.

Nashville Power Outage Tracker

Live power outage data from Nashville Electric Service (NES), showing the number of active outage events, total customers affected, crews dispatched, and overall severity level. The tracker updates every five minutes and includes direct links to the NES outage map and the NES outage hotline (615-234-0000).

Weather & Emergency News

RSS feeds from Nashville's major local TV news stations (WKRN, WSMV, WTVF, and Fox 17) are filtered by keyword to surface only weather-related, storm-related, power outage, and emergency stories. The result is a focused news feed that cuts through the noise and shows you what matters when conditions are changing.

Social Updates

Quick links to the most important weather and emergency accounts on X (Twitter), including @NWSNashville, @NashSevereWx, @NESpower, @ABORANA (TEMA), and @NC5.

Who Made This

NashvilleWeather.Org is created by Nashua Labs, a Nashville-based development studio. The site is a community project — it's free to use, contains no paywalls, and is not affiliated with any government agency, news outlet, or commercial weather service.

Technical Details

The site is a static, single-page web application built with vanilla HTML, CSS, and JavaScript — no frameworks, no build steps. It uses Tailwind CSS for styling, Leaflet.js for the interactive map, and one optional serverless function (Netlify Functions) for RSS feed proxying and outage data aggregation. The entire site loads in under 400KB before radar tiles.

The site is deployed on Netlify and the source code is open source under the MIT license.
