Get Weather information using Yql query lat,long parms

I am using the following YQL query to get weather information

http://query.yahooapis.com/v1/public/yql?q=select%20item%20from%20weather.forecast%20where%20location%3D%2248907%22&format=json

Is there any way to get weather information using longitude, latitude as YQL query parameter.

You could use a sub-select to go from a latitude/longitude pair to a WOEID like

SELECT * FROM weather.woeid 
WHERE w IN (
    SELECT place.woeid 
    FROM flickr.places(1) 
    WHERE (lat,lon) in (55.948503,-3.198931)
);

(Try in YQL console)
