I've been using
Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground for years and there's a ton of good stuff on here. Good radar and you can see 24 hours of archived radar.
You can also find historical data for all major weather measurements in 1 hour increments. You can look at it by the hour, day or week. Helps to update the log book if you have't kept up with it.
I've found the marine forecast very reliable and you can access all of the local measurement stations to see the raw data. Decent mobil app too.
