I just have redirected YoWindow currrent weather (METAR) to new source.
Now METAR weather is received from this page
http://www.aviationweather.gov/adds/metars/
We did this because of the changes in NOAA
"On or about April 4th, 2012, request for METARS through this service will be redirected to..."
http://weather.noaa.gov/weather/metar.shtml
Let me know if you to experience any problems with the current weather today or tomorrow.
