What do you use for looking up weather? All the top results generally have tons of advertisements, or do not provide a weather map, or are a horrible user interface.
<a href="https://weather.gov" rel="nofollow">https://weather.gov</a><p>I live in a coastal area with highly localized weather, and weather.gov gives me by far the best forecast. Sites which only have city-level granularity don't work well when the temperature can be 5-10F different less than a mile away.
While it doesn't count for much if you're outside of Australia, the BOM (Bureau of meteorology) is probably the best I use.<p><a href="http://bom.gov.au" rel="nofollow">http://bom.gov.au</a>
I like Weather Underground for most things. The 10-day graph presents information in a way I find useful and easy to understand. However, for the weather <i>right now</i> I like AccuWeather's MinuteCast. It's eerily accurate. I use them to plan my runs on variable days, and I almost never get caught in the rain if they say it's supposed to be clear. On the other hand, if it says it's going to rain in 23 minutes and I decide to wait for a bit, it practically always <i>does</i> rain in exactly 23 minutes. Ditto for snow in the winter. The exact amounts might be off, but the timing is usually spot on.

When it comes to planning an alpine climb, I use <a href="http://www.mountain-forecast.com" rel="nofollow">http://www.mountain-forecast.com</a> to judge what sorts of gear I might need. Super niche use-case, but it's better than anything else I've found.
Weather Underground[1], I love their 10-day forecast view with the graphs of temperature, precipitation chance, pressure, and winds.<p>1) <a href="https://wunderground.com" rel="nofollow">https://wunderground.com</a>
