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.
And, I (ab)use the sites of local folk who have their weather stations and webcams available when I'm about to go for a bike ride.

Very intuitive and simple weather map

To excerpt the most recent (8:14PM EDT) NYC office's discussion:
"As a result, expect most precipitation to be focused mainly during the evening hours. Hi-resolution models have been suggesting that the overnight hours could be mainly if not entirely dry. This is due to 850 hPa warm front lifting to the north by around 6z and a dry slot moving in from the SW (DC/PHI area). For now, have just lowered pops to chance. If trends in the high resolution models hold, pops will need to be lowered further if not removed for the overnight hours with future updates."

Out of the scope of the question, my local TV news station gives the most accurate forecast of any other source. Also handy are top of hour terrestrial radio updates and NOAA Weather Radio.
Is great if you’re in the terminal.
Provides the means for me to look for myself :)
