I've been using weather.com for years for weather/forecast info but switched to AccuWeather about six months ago, partly because #Firefox was shoving it in my face on every new tab and partly because the former site was bombarding me with ads and sluggish web performance.
Recently, I've started using the National Weather Service, weather.gov. The wealth of information they provide upfront is great, too.
While there is some variation between all three sources, Accuweather.com has been, interestingly, the least accurate.
I was under the impression these 3rd party sites source their data from the NWS. But I guess this isn't the case?! 🤔
