What are the right Weather Underground Stations?

Race I have coming up at 9.20pm in Brazil.
Currently it is raining in Brazil going by the station on weather underground but iGP practice is saying it is dry at the moment. I need someone to tell me what is the right station to be watching.

Never mind Station on site just changed. Saying it is cloudy now :D

Don't forget there is a 10/15m delay.

Now see why Jack wants an in-house weather system. wet, dry, wet, dry, wet, dry, wet.
variable weather conditions are just no fun and iGP has a 35minute delay to the real-time weather changes :|

I imagine the delayed weather information (aka stale info) is cheaper than real-time weather information.

I know in stocks trading, some websites display delayed stock prices in certain instances because the information is stale, therefore cheaper.

If you wanna find some, just type "Bahrain International Circuit" or "Sepang International Circuit" for example.

I've just started using the 6hr rain forecasts eg http://www.wunderground.com/cn/shanghai/zmw:00000.1.58362/precipitation

Live weather is a double edged sword

The biggest problem with the current system is it severely penalises those managers who can't/don't attend races.

But if you have a league with several managers online for the race and the weather is variable then it really adds to the tension and possibility to do well if your driver/car is less competetive.

Cant always go by the expected precipitation over the next six hours. Few times I have seen it not being right.
Like even the peoples on tv get the forecast wrong from time to time. :)

Here is a list of stations. Not sure if they are the right ones though.

I have never been too worried about finding the right station. It can be in the same geographical area as the race track and the weather information will be just as accurate.

Same as every other weather station guess work. Weather for my area today is wet and windy, but it's sunny and windy with clear skies :D
