If you goto https://www.windy.com/ and enable the Airports function by clicking on the aircraft icon in the bottom right panel, you will see airports as a small circle. Those circles which are green have a metar available by clicking on the green circle. You can then see whether you are likely to be able to use that airport with real-time weather.
Other useful items available in the menu (right-hand side of screen) are cloud base, weather radar, low clouds etc.
