THE FORECAST MODEL SOUNDING MACHINE

This gives you a forecast sounding from the National Centers for Environmental Prediction (NCEP)'s operational RUC, WRF, GFS or UKMET models for any site that produces a METAR. A comprehensive list for the US, Canada and Mexico is here. Please note that only stations in the Western Hemisphere will work. Also, if you get no sounding or an incomplete one, data may still be coming in. Try 30 minutes later, or an hour later for the Aviation model. AVN comes in roughly at 8Z and 20Z. MRF comes in by 13Z.
