A meteorologist colleague informed me of https://www.yr.no/ and it has a version in English. It is what I usually use along with weather.gov. Their short and long-term World-Wide ECMWF forecasts are really nice as are the meteorograms. Yeah dump weather.com.
Edit: Ohh and one more: Jeff Masters and his crew at Weather Underground (wunderground.com). For example another nice meteorogram: https://www.wunderground.com/forecast/us/co/boulder/KCOBOULD...
